321 Stainless Steel Sheet

321 Stainless Steel Sheet  

Type 321 stainless steel is Ni - Cr - Ti austenitic stainless steel,321 stainless steel plate used in demanding outdoor in the field of chemical, coal, petroleum industry machinery, building materials heat-resistant parts and heat treatment are difficult parts.

321 stainless steel of Ti as a stabilizing element exists, but it is also a hot steel, in terms of high temperature is better than 316 l. 321 stainless steel in different concentration and temperature of organic acid and inorganic acid, especially in oxidizing medium has good abrasion resistance, used in the manufacture of the lining of wear resistant acid containers and equipment and pipelines.

321 stainless steel plate in stainless steel plate is the difference between other:
321 contains ti,316 contains molybdenum
Neither 304 nor molybdenum containing titanium
Mo2Ti molybdenum and containing titanium, 316 l, the optimal performance, 321/304

Austenitic stainless steel is equal to the domestic 1 cr18ni9ti
