Indana Steel Guide – Think Before using stainless steel fasteners


ssfastenerYou might be aware of the fact that the use of stainless steel fasteners is quite popular. This is not without reason. One primary reason for the same is that stainless steel fasteners are corrosion-resistant and at the same time have recyclable properties. A major advantage is also the fact that they offer resistance against any level of usage severity.

Besides they also have great load-bearing characteristics in both hot as well as cold weather. However, if you are not able to handle these fasteners properly; your entire set up could get damaged. Here are few mistakes you certainly cannot afford to make while using stainless steel fasteners.

Grade selection

One of the most important thing you must take note of while using stainless steel fasteners is to check the grading of the steel.  Generally you might know that grade 304 and 316 are the two most commonly employed stainless steel grades.

These are the ones which offer greater resistance to corrosion better than any other grade available in the market.  On the other hand you must also know that for an environment that is highly susceptible to corrosion, the 316 stainless steel is a perfect choice, given the resistance it provides against the effect of metal oxidization.

Atmosphere is susceptible to contamination

When it comes to using stainless steel fasteners, the bare part of the stainless steel exposed to the atmosphere is susceptible to contamination by metallic dust. This is what can ultimately lead to formation of rust on the surface and thereafter ultimately causing gradual decay of the material, internally.

A very general common example is that of the sticking of iron fillings that result from grinding of steel.  Experts in the field recommend for covering this exposed parts with stainless steel fasteners during the period of operation.


The fact that needs to be taken note of is that galvanic corrosion occurs when two different metals and alloys come in electrical contact with each other to apply corrosive effect. This can not only affect the stainless steel fasteners, but at the same time could also lead to adversely affect the metal that comes in physical contact with the particular fastener.

It is of utmost importance that you closely investigate if there is a possible situation of a galvanic corrosion taking place and to what extent it can be inhibited. This can be prevented by using tools made of stainless steel. It is indeed a  a smart choice, since similar electro potentials do not trigger corrosion. You could also o use nylon washers as a barrier to isolate the metals from touching each other.

having a higher percentage of manganese

You must take note of the fact that stainless steel fasteners of the 200 series are chromium deficient. This is apart from having a higher percentage of manganese and lower proportion of nickel. These type of combinations is generally very unsuitable to resist the action of rusting, as compared to the corrosion-resistant properties offered by 316 stainless steel studs.

Greater durability of the stainless steel fasteners

In order to ensure greater durability of the stainless steel fasteners you need to ensure that regular cleaning schedules employed for the equipment. You must not also allow the contaminants to settle over a long period of time. If this happens it does not only become difficult to carry out cleaning practices, but also to restore the distorted appearance of stainless steel. It is also advisable that you expose the surface to rainwater, so that all the dust particles wash off and there is no damage done to the protective layer of the steel.


You need to realize that uneven finishing of stainless steel fasteners can leave space for entrapment of dusty particles that can destroy the protective layer of chromium oxide. This in turn provides the necessary resisting action against corrosion.   A smoother finish would eliminate the possibility of particle settling. It also allows for easier cleaning practices.

To conclude we hope that while or using stainless steel fasteners you would avoid making the above mentioned mistakes. In case you are looking for the best quality flange guards, stainless steel fasteners please get in touch with us at Indana Steel.


Simple Ways to Reduce After Effects of Leakage and Mist Formation


If your business involves transportation of hazardous chemicals through pipes, then you would know that it involves considerable risks. With time the pipes gets damaged and become weak and vulnerable especially at the joints.

This might lead to leakages and spray outs and mist formation which could cause major industrial accidents. So efforts must be made to prevent them at all costs. However we at Indana Steel being one of the leading suppliers of flange guards suggest some simple steps which you can follow to prevent such major accidents. These are very cost effective as well. Let us see what they are.

Know how to prevent accidental spray outs and leakages

Flange Guards

Flange guards are safety shields which can be installed at the joints and at the valves. These shield the joints where they are installed against any spray outs and leakages and thus prevent any direct contact with the personnel and also with the surrounding equipment.

Even if there is a leak therefore the catastrophic impact gets much limited as a result. These may be made from different types of materials which you can use to suit your requirement bases on the budget you allocate for the purpose. Out of them the PTFE flange guards are very effective as they can sustain high pressures and temperatures.

Using PTFE Ring Gaskets

Apart from flange guards you could also make use of the PTFE ring gaskets to minimize the effects of any leaks or mist formation. These help since they create a static seal between two mechanical members of the flange joints. PTFE material is one which remains unchanged even in extreme conditions.

So they can provide the adequate protection in most conditions even when there is very high temperature or under extreme pressures. Thus any dangerous accidents might easily be averted from happening with their use.

You could also use Bolt Protection caps

Apart from the above two mentioned you can also make use of bolt protection caps which can ensure the safety of your employees and equipment at your plant. The bolt protection caps prevent the bolts from coming in direct contact with the hazardous liquids which might lead to corrosion and ultimately lead to spray outs. So these are also quite effective or preventing any major damages from such spray outs.

In conclusion we can say that when it comes to your business safety is definitely one of your top priorities. This is more so keeping in view the strict statutory requirements in regard to meeting the safety standards of the various authorities.

You might have had the impression that upkeep of meting these standards is a very expensive affair which involves many hassles. However we hope that with the points mentioned above you can make your plant or factory a much safer place and there is no major cost involved as well.

This might determine the strength and durability of tan entire structure.

Thus we at Indana Steel being one of the leading suppliers of various kinds of bolts and fasteners thought of informing you about the type of steel used for bolts. This will help you to decide would suit your purpose.

Factors on which the selection of bolts and fasteners depend

There are many considerations which need to be taken before you decide on the bolts or the fasteners which are to be used. Selecting the material must be made of factors like environment (corrosive or temperature extremes), weight, magnetic properties reusability and expected life.

Types of Steel bolts

Steel is the most commonly used material for the production of fasteners. It constitutes nearly 90 percent of all fasteners manufactured annually. This popularity of this material stems from its high degree of formability.

This is again coupled with tensile strength and they are also much more durable. In comparison to other metals , steel  also is comparatively inexpensive to fabricate. It is often processed with zinc or chrome plating. These  can also be formed without any surface treatments. Carbon steel is the most widely used type of steel.

There are various grades of steel which are used .Grades 2, 5, and 8 are typically the standard for carbon-steel based screws and bolts. With alloyed carbon steel is  a higher-end variation on these metals. The mechanical strength of this is very high .

Grades of carbon steel – 4 Gread


Grade 2 carbon Steel: This is a low carbon category and is also the least expensive. However they are also the least durable, types of steel. This grade 2 steel materials is much is widely used.

Grade 5: Grade 5 steels are produced from unalloyed medium carbon groups. These are  type 1038. They are mostly work-hardened to improve their strength. This type of carbon steel is mostly used in automotive applications.

Grade 8: These grades of steels are typically medium carbon alloys. These are types 4037 and 4340. They are also work-hardened to a high degree. This is what makes them stronger and better-suited for mechanically straining applications. These may be used in vehicle suspension systems.

 Alloy Steel: This is an alloy formed with high-strength carbon steel that is thermally treated. Alloy steel has low corrosion resistance. Thus it benefits from additional coating. These steels are extremely strong. However they can  can be rigid and brittle at the same time.

To conclude we hope that we have been able to give you a fair idea of the types of materials used for steel bolts and fasteners. In case you are looking to procure steel bolts and fasteners, then do it from Indana Steel.

Pipes and Flange Correlation between them

Pipes form an important part of many industries. Industrial pipes are often used to transport fluids and solids according to the needs of the industry. There may be various types of industrial pipes which may be used in terms of its shape, material, etc. They may at times carry hazardous material as well.

In such cases extra care is to be taken as if these get sprayed out from such pipes it can be a great threat to humans, equipment and environment at large. This is why extra safety precautions are supposed to be taken. Here is where the flanges become important. Let us first understand what flanges are and why they are so important for pipes.

What are pipe flanges? What is their role? 

Pipe flanges can be described as protruding rims, edges, ribs, or even collars used to make a connection between two pipes. They can also be used between a pipe and any type of fitting or equipment component. They are generally used for dismantling piping systems which may be temporary or mobile installations.

Pipe flanges usually are simple mechanical connectors. They are usually used in places where there are high pressure piping applications, where there may be extreme temperatures as well. These may be made from different materials depending on the needs of the customers.

Types of Pipe flange guards

Piping flanges may be made up of different materials. These may be made up with stainless steel which are meant for those sectors where there is requirement of very high strength. Apart from this they may also be  Polypropylene Strap Type ( PP ) Flange Guards . 

Along with this there are pipe flange guards which are made up from PTFE or Polytetrafluoroethylene . This is a synthetic material that has a large number of uses. They offer low friction and are contaminant free. It is non flammable and also non reactive. Thus this makes it ideal work connecting pipes and providing extra protection. In case you are looking for less expensive pipe flange guards there are such types as well.

So we can see that there is a strong correlation between industrial pipes and flange guards. Flange guards help to connect different sections of pipes and also provide extra protection. This becomes necessary in many   industries like petrochemicals, etc. To ensure maximum safety for your plant, equipment and humans at large you must use the best quality flange guards.
