SS 904L Stainless Steel Sheets Manufacturer
What are SS 904L Stainless Steel Sheets?
SS 904L stainless steel sheets are made from a non-stabilized austenitic stainless steel alloy with high levels of chromium, nickel, molybdenum, and copper. This composition offers exceptional resistance to acids, chloride-induced stress corrosion, and pitting/crevice corrosion—making it ideal for sulfuric acid handling, seawater exposure, and pharmaceutical-grade processing.
