Stainless Steel 904L Rectangular Bars are made up of about 19–23% chromium, 23–28% nickel, 4–5% molybdenum, and 1–2% copper, all while maintaining a low carbon content (≤0.02%). This high-alloy austenitic stainless steel is known for its exceptional corrosion resistance, particularly against strong acids and environments rich in chlorides. Its mechanical properties include a tensile strength ranging from 490–710 MPa, a yield strength of at least 220 MPa, and an elongation of 35% or more. The alloy also boasts excellent toughness, good weldability, and strong resistance to pitting, crevice corrosion, and stress corrosion cracking, making it a great choice for demanding industrial applications.
