Stainless Steel 316/316L Nuts

ASTM A193 316 Nuts, 316L Stainless Steel High Tensile Nuts, Stainless Steel 316 Serrated Flange Nut, Stainless Steel DIN 1.4401 Coupler Nuts Suppliers in India.

Ranfit Metal & Alloys is a prominent exporter of SS 316 / 316L Nuts, which has deep drawing quality. Stainless Steel 316 Nuts can be formed into a variety of shapes and can be used without annealing. The additional nickel makes Stainless Steel 316L Nuts a bit sturdier (meaning the tines of a fork are slightly more difficult to bend back and forth). Stainless Steel UNS S31600 Nuts is used in heavy gauge components for improved weldability. Stainless Steel UNS S31603 Nuts is readily brake or roll formed into a variety of components for applications in the architectural and transportation fields. 316 Stainless Steel Nuts is also used in all commercial, domestic and industrial fields because of its good corrosion and heat resisting properties. Some small parts such as clamps and mounting feet, constructed by 316L Stainless Steel Nuts are specifically marked.

Stainless Steel 316 Hex Head Nuts contains high nickel content that is typically between 8 percent and 10.5 percent by weight. Stainless Steel 316L Square Nuts drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. Stainless Steel 316 Lock Nuts has low temperature properties that respond well to hardening by cold working. Stainless Steel 316L Eye Nuts is widely used because of the ease in which it is formed into various shape. Stainless Steel 316 Wing Nuts is a sought after material for use in severely corrosive conditions.
