Stainless Steel 304L EFW Pipes is a low-carbon austenitic stainless steel grade that contains chromium (18–20%), nickel (8–12%), and a reduced carbon content (≤0.03%), along with trace elements like manganese, silicon, sulfur, and phosphorus. This unique composition gives it outstanding corrosion resistance, particularly against intergranular corrosion. Its mechanical properties include good tensile and yield strength, high ductility, and reliable toughness, even in low temperatures. The low-carbon structure enhances its weldability and reduces carbide precipitation, ensuring strong performance in environments that require clean welds and consistent structural integrity.
