Stainless steel 321 Round Bar

ASTM A276 Type 321 Rod, Flat and Hex Bar manufacturer in India

Stainless steel is the most used steel in the world. Great Steel & Metals is a well-known supplier and Stainless Steel 321 Round Bar Manufacturer. We have served a large customer base for several years. The 321 stainless steel is an austenitic steel stabilized with titanium. The addition of titanium makes the steel more corrosion resistant to general corrosive agents.

It also makes the material greatly resistant to intergranular corrosion because of the reduction in carbide precipitation while welding. Our 321 Stainless Steel Rod can be used in place of 304 stainless steel when the need for much corrosion resistance is needed. But the heat treatment is not possible on the 321 material. However, it could be cold worked to improve the strength if necessary. The applications of the material could be seen in waste treatment plants, petroleum refineries, food processing equipment, aerospace industry and others. There are also other types of bars in this range of products. We produce the WERKSTOFF NR. 1.4541 Stainless Steel Flat Bar which is used in frames and lattices such as door and window frames. The flat bars could also be used in structural applications as supporting elements such as the construction industries. There are other shapes such as the SS 321 Hex Bar which are mainly used for high tensile strength. The UNS S32100 Round Bar produced by us is of high quality. Our ASTM A276 Stainless Steel 321 Flat bar could also be supplied in any different size. Contact us for further details.
