Aditya Stainless stands out as a top manufacturer and supplier of Stainless Steel 321 Flanges, proudly based in Kolkata, India. These flanges are made from titanium-stabilized austenitic stainless steel, which gives them remarkable resistance to intergranular corrosion and high-temperature stress. Perfectly designed for high-temperature applications, SS 321 flanges boast exceptional weldability and mechanical stability. They’re crafted to meet international standards like ASTM A182 and come in various types, including weld neck, slip-on, blind, socket weld, and threaded flanges. Our flanges are extensively used in power generation, chemical processing, thermal plants, and other heat-intensive industries.
Stainless Steel 321 Flanges are composed of chromium (17–19%), nickel (9–12%), and titanium (at least five times the carbon content), which helps stabilize the structure against carbide precipitation. With a tensile strength ranging from 515 to 620 MPa, a yield strength of 205 MPa, and an elongation of about 35%, these flanges hold their mechanical integrity even in high-heat settings. The addition of titanium ensures they maintain strength and resist corrosion after welding, particularly in heat-affected zones. This alloy is particularly well-suited for applications that experience repeated temperature cycling and long-term exposure to corrosive environments.
