The austenitic stainless steel varieties used in the soda ash industry are the most widely used in high nickel molybdenum 904L (015Cr21Ni26Mo5Cu2) stainless steel and molybdenum containing 316L (022Cr17Ni12Mo2) stainless steel. 904L stainless steel not only has a very high chrome-nickel content, but also has a high molybdenum content, respectively, chromium 19%~23%, nickel 23%~28% and molybdenum 4%~5%, so in the production of soda ash, 904L stainless steel shows a good resistance to comprehensive corrosion and pitting resistance. In addition, 904L stainless steel has good cold and hot workability. In Europe, 904L stainless steel is considered to have excellent corrosion resistance comparable to titanium in soda ash equipment, and 904L stainless steel is widely used to replace titanium in soda ash industry applications in some titanium-poor countries. 904L stainless steel can not only be used as sheet metal to become the shell material of pressure vessels, but also as forgings and castings used in heat exchanger tubes and pumps. To 316L stainless steel here, both the alloy content ratio and corrosion resistance are significantly inferior to 904L stainless steel, but it can also be applied to soda ash equipment, pipelines, meters and valves. Anyway,no matter you need 904L or 316L ,HUA steel company can provide you very well, just share me your information!
