ASME SA240 2000mm Width Alloy 321/S32168 Heat Resistant Stainless Steel Plate
Grade 321 / 321H Stainless Steel Sheet UNS S32100 Overview
Grade 321 stainless steel is a titanium-stabilized alloy designed for service in the 1000-1600°F temperature range. For optimal resistance to intergranular corrosion and polythionic acid stress corrosion cracking at temperatures up to 1600°F, a stabilizing treatment at 1550-1650°F followed by air cooling is recommended.
This grade is readily weldable using all common methods, including submerged arc welding, with appropriate fillers such as AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, it offers similar machining characteristics to 304 stainless steel.
Available Forms: Sheet, plate, coil, strip, wire, pipe, tube, bar, profile, round, flat, square, hexagonal
