Stainless Steel 904L Bars are made from a high-alloy austenitic stainless steel containing approximately 20–23% chromium, 25–28% nickel, 4–5% molybdenum, and small amounts of copper. This composition provides outstanding corrosion resistance against acids, chloride solutions, and oxidizing environments. The alloy also offers excellent toughness, dimensional stability, and moderate hardness. Typical tensile strength ranges from 500–700 MPa, with a yield strength around 200–350 MPa. These bars are highly durable, resistant to pitting and stress corrosion, and suitable for applications demanding reliability in harsh chemical and marine environments.
