Chanchai Stainless supplies Stainless Steel 904L Pipes in Bangkok, Thailand. These pipes are engineered for excellent corrosion resistance in harsh environments. As a low-carbon, high-alloy austenitic stainless steel, 904L offers strong protection against pitting, crevice corrosion, and stress corrosion cracking. With copper added to the mix, they resist strong reducing acids like sulfuric acid. These pipes combine toughness, strength, and ease of welding, making them suitable for demanding chemical and industrial uses. Chanchai Stainless guarantees high-quality production, providing 904L Pipes that perform reliably in industries that need long-lasting, high-performance stainless steel solutions in corrosive and chloride-rich conditions.
Stainless Steel 904L pipes include chromium (19-23%), nickel (23-28%), molybdenum (4-5%), and copper (1-2%). This blend enhances resistance to reducing acids and attack from chlorides. They have a tensile strength of around 490-710 MPa and yield strength near 220 MPa. With an elongation rate of 35% or more, they offer toughness and ductility. The alloy remains oxidation-resistant at temperatures up to 870°C. Corrosion resistance is better than 316L, especially against chlorides and sulfuric acid, making 904L a dependable choice for industries that need strong stainless steel with excellent chemical stability.
