You 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.
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.
MAKING CONDITIONS FAVORABLE FOR GALVANIC CORROSION
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.
