Austenitic Stainless Steel 321
Petroinox Pipes and Tubes Private Limited is a leading Manufacturer of Austenitic Stainless Steel 321 Pipes and Tubes in India. The 400 series in the Austenitic Stainless Steel 321 products have about 11-12% Cr and 12% Mn. The grain structure of Austenitic stainless steel is BCC (body centred cubic) in comparison to stainless steel, which has its grain structure as FCC (face centred cubic). The alpha iron in Austenitic stainless steel is what gives it very high magnetic properties. The 10-12% Cr in the Austenitic SS 446 makes the metal corrosion-resistant. Though it has lesser resistance than other alloys in the series, it possesses excellent dimensional stability, suitable welding properties, appropriate pitting resistance, and low cost. The alloy is principally used in the lining of pressure vessels. It has a maximum of 0.08% carbon content, which prevents it from getting brittle at allowable temperatures. It has a shear modulus of 76 GPa, making it suitable for dynamic applications and require shear strength. The alloy is typically furnished in the annealed condition. Electric resistance as well shielded fusion welding methods are normally used in its production.
