Product Description
ASTM A240 ASME SA240/SA240m S32168 321 Stainless Steel Plate
Grade 321 / 321H Stainless Steel Sheet UNS S32100 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 followed by air cooling is recommended to provide maximum resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
This grade is readily weldable using all common methods, including submerged arc welding. Appropriate weld fillers include AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, 321 stainless steel offers similar machining characteristics to 304 stainless steel.
