Description

321 stainless steel sheet and plate

321 stainless steel sheets and plates are used in applications up to a temperature range of about 900°C. It combines high strength, anti-oxidation and peeling, and subsequent phase stability against corrosion by aqueous solutions.

Product Introduction

Ti in 321 stainless steel plate exists as a stabilizing element, but it is also hot-strength steel, which is much better than the 316L stainless steel plate in terms of high temperature.321 stainless steel plate is in organic acid and inorganic acid of different concentrations and different temperatures, especially It has good abrasion resistance in oxidizing media and is used to manufacture the lining and conveying pipeline of wear-resistant acid containers and wear-resistant equipment.

The 321 stainless steel plate is a Ni-Cr-Mo austenitic stainless steel plate. Its performance is very similar to that of the 304 stainless steel plate. However, due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high-temperature strength. Due to the addition of titanium, it effectively controls the formation of chromium carbide.
