904L grade stainless steel is a stainless steel grade containing very high amounts of chromium, nickel and molybdenum. This grade, also called super austenitic stainless steel, has very good corrosion resistance. This stainless steel grade is particularly resistant to sulfuric acid and heavily chlorinated environments. This stainless steel quality, which has a much better corrosion resistance than 1.4462 duplex quality stainless steel material, has a very good antimagnetic structure.
904L quality stainless steel is a stainless steel quality that is frequently used in highly corrosive environments where there are very difficult conditions. 904L (1.4539) quality stainless steel material is preferred in acidic environments that normal stainless steel cannot withstand, in the petro-chemical industry where excessive rusting and corrosion occur, in paper mills, purification facilities, gas production and filling facilities, medical applications, in short, wherever corrosion resistance must be at a high level. is being done.
