Stainless Steel 904L Welded Pipes are crafted from a high-alloy austenitic stainless steel that includes Chromium (19–23%), Nickel (23–28%), Molybdenum (4–5%), and Copper (1–2%) to boost corrosion resistance. The low carbon content (≤0.02%) helps prevent carbide precipitation, enhancing weldability and resistance to intergranular corrosion. These pipes offer a tensile strength of around 490 MPa, yield strength of 220 MPa, and an elongation of 35%. SS 904L maintains excellent toughness and formability, even at cryogenic temperatures, and effectively resists pitting and crevice corrosion in harsh acidic and chloride-laden environments.
