Product Description
S32168 Stainless Steel Plate Hot Rolled SS 321 Plate
Grade 321/321H Stainless Steel Sheet UNS S32100 is a titanium-stabilized austenitic stainless steel designed for high-temperature service in the 1000-1600°F range. This grade offers excellent resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
Product Overview
321 stainless steel is readily weldable by 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, it offers similar machinability to 304 stainless steel.
Available Forms
- Sheet, Plate, Coil, Strip
- Wire, Pipe, Tube, Bar
- Profile, Round, Flat, Square, Hexagonal
