Product Description

321 Stainless Steel Plate Hot Rolled for Pressure S32168

Alloy 321/321H Heat Resistant Stainless Steel Plate

Product Overview

Grade 321/321H stainless steel is a titanium-stabilized alloy designed for high-temperature service in the 1000-1600°F range. This material offers optimal resistance to intergranular corrosion and polythionic acid stress corrosion cracking when properly stabilized.

This stainless steel grade is readily weldable using common methods including submerged arc welding, with recommended fillers being AWS ER347 bare wire and E347 covered electrodes. It features a machinability rating of 45% relative to AISI B1112.
