Nascent Pipe & Tubes is one of the well-known exporting house and dealer of high quality Stainless Steel 317 Fasteners (Bolts / Nuts), which contain sufficient chromium to undergo passivation, forming an inert film of chromium oxide on the surface. Since iron oxide has lower density than Stainless Steel 317 Hex Head Bolts, the film expands and tends to flake and fall away.
This layer prevents further corrosion by blocking oxygen diffusion to the surface of Stainless Steel 317 Hex Head Nuts and stops corrosion from spreading into the bulk of the metal. Passivation in Stainless Steel 317 Square Bolts occurs only if the proportion of chromium is high enough and oxygen is present in it.

Resistance to corrosion and staining, low maintenance, and familiar lustre make Stainless Steel 317 Square Nuts an ideal material for many applications. Stainless Steel 317 Eye Bolts is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment (for example, in sugar refineries). Storage tanks and tankers used to transport orange juice and other food are often made of Stainless Steel 317 Eye Nuts, because of its corrosion resistance.

High oxidation resistance of Stainless Steel 317 U-Bolts in air at ambient temperature is normally achieved with addition of a minimum of 13 % (by weight) chromium, and up to 26 % is used for harsh environments. Stainless Steel 317 Wing Nuts is also used as an automotive and aerospace structural alloy and construction material in large buildings.
