Stainless steel.
Stainless steel is a steel that contains chromium at 10.5%. The content might have varied in different grades. Stainless steel included austenite steel, ferrite steel, duplex, and more than 100+ types.

SS fasteners
SS fasteners consist of varied grade but the major one is 304, 304L, and 304H since they are strongest than all grade.

Stainless Steel 304 Fasteners

SS 304 fasteners are manufactured from basic austenitic steel. It has 18% of chromium and 8% of nickel. They have up to 515mp tensile strength. It approximate percent of elongation is 40 with maximum strength. It can be utilized in a chloride-rich environment.

SS 304L Fasteners are composite of chromium and nickel. It protects itself from the most general corrosion. It can withstand high temperatures and pressure too. in special applications, they have proved to be applicable. They are mostly used in pressurized containers and high heat applications.

SS 304H fasteners are high in carbon as compared to SS 304L grade. The carbon content in this grade is between 0.04 to 0.1 percent. Because of this, it can tolerate high temperatures. in the nonreceptive atmosphere, they are used widely.

We are always working hard to develop competent quality products. We understand the need and requirements of the customers and provide them with the same. We customize the products as per the specification of the clients. We offer an affordable price. Along with products, we offer the best service to them because we value them.
