Product Details of 321 Stainless Steel Round Bars:

321 UNS S32100(AISI 321,1.4541) Stainless Steel Round Bars:321 stainless steel has excellent high temperature stress rupture performance and high temperature creep resistance stress and mechanical properties. Due to the addition of Ti element inside, it has better resistance to grain boundary corrosion and high temperature strength. Processing capacity is similar to 304.

The process flow of the 321 stainless steel bar production line: 

billet acceptance → heating → rolling → double-length cutting → cooling → cutting → inspection → packaging → measurement → storage.

Product Description

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

321 stainless steel is widely used in outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts for building materials, and parts with difficult heat treatment.
