Product Introduction

SS 321H Plate is a higher carbon version of 321 (0.04 - 0.10). UNS S32109 has higher creep resistance and higher strength at temperatures above 1000°F (537°C). AISI 321H stainless steel is an alloy consisting of chromium, nickel and titanium that has excellent corrosion and heat resistance and will not deform or harden at extreme temperatures. We are an ASTM A240 Type 321H supplier with 15+ export experience, contact us for more information and free quotes!

Alloy 321 Vs. 321H

SS321 and 321H stainless steel plates have different strength and corrosion resistance. 321 is a non-heat-treatable stainless steel that is often used in applications that require weldability and toughness. 321H is a heat-treated version of 321 stainless steel that exhibits higher strength at elevated temperatures and offers better formability.
