Stainless Steel 316l Bolts And Nuts

Astm A193 UNS S31603 Fasteners manufacturer in India


Stainless steel has a variety of grades that have a high carbon content. High content of carbon is vulnerable to corrosion during welding. The weld zone can also have carbide precipitation due to the heat and presence of carbon. One can avoid this by reducing the carbon content in the alloy used while manufacturing bolts, nuts, and tubes. 316L Stainless Steel Fasteners are amongst those whose carbon content has been reduced and has an added content of nitrogen to it. Hence stainless steel 316l bolts and nuts are said to be a nitrogen enhanced variety of 316 grade and have the letter L mentioned in front of it due to the reduction of carbon.

The reduction of carbon from Stainless Steel 316l Nuts makes it weaker as compared to the original alloy. Therefore infusion of SS DIN 1.4404 Fasteners restores the lost strength in it. Though 316l stainless steel threaded rod does not display strength equivalent to the original alloy, yet it has similar properties. 

Furthermore, the infusion of nitrogen to 316l Stainless Steel hex head screws increases the resistance of the product to pitting. Overall in terms of corrosion resistance 316L and 316 grade display similar properties in SS UNS S31603 Fasteners. Hence they are also referred to as marine grade. 316l stainless steel bolts are used in marine construction, saltwater desalination, and other applications in the sea.

We provide you the best quality Astm A193 316l Fasteners at a competent price and ensure timely delivery of our product without giving you a single reason to complain.
