Stainless Steel Fasteners

 

 

 

 

One of the most commonly used and favoured alloys used across the globe, any SS Bolt manufacturer would be able to find you the most suitable grade for the application these fasteners are to be used for. According to SS Nut Bolt Manufacturer in Mumbai, the most utilized stainless steel grade to produce fasteners is grade 304.

Not only is alloy grade 304 cheaper in comparison to most SS alloys, but it also provides resistance to corrosion. In general, chromium containing Passivated SS Fasteners offer good resistance to oxidation corrosion. This is because the chromium from the surface of these fasteners reacts with oxygen in the atmosphere to form a passivating oxide layer, which prevents oxidation corrosion. Typically stainless steel bolts manufacturers in India offer the passivated fasteners to those industries which deal with oxidizing conditions.

 

Moreover, high temperature steel grades such as grade 321 Self-Drilling SS Fasteners are able to perform superbly despite being in extremely heated temperature settings. Coated / Coloured/ Polished SS Fasteners offer some levels of protection against corrosion. On the other hand alloy 316 is a material which can be used to produce Stainless Steel Marine Fasteners. For those Heavy Duty Stainless Steel Snap Fasteners which require good corrosion resistance after being welded, buyers are given a choice of low carbon containing alloys. Low content of carbon in the stainless steel nut bolt prevents intergranular corrosion.

Difference between grade A2 and A4 in Stainless steel fasteners

Fasteners are components used to connect pieces of pipes together or other fasteners together. They are produced in different grades of metals. The stainless steel is one of the most used categories of metals for fasteners. The A2 fasteners are made from 304 type steel which has 18% chromium and 8% nickel in the composition. The A4 fasteners are made from 316 type steel which has 18% chromium, 8% zinc and 2-3% molybdenum. So that the A4 grade fasteners have high corrosion resistance than the A2 grade fasteners due to the addition of molybdenum in the composition.
