Product Description
Hot Rolled 321 Stainless Steel Plate Stock S32168
Available in 3-14mm thickness with titanium stabilization for high-temperature applications
Product Overview
321 stainless steel is a titanium-stabilized grade specifically designed for service in the 1000-1600°F temperature range. For optimal performance at temperatures up to 1600°F, a stabilizing treatment at 1550-1650°F with air cooling is recommended to provide maximum resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
Manufacturing & Processing
321 stainless steel is readily weldable using all common methods including submerged arc welding. Recommended weld fillers include 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.
