ASTM A240 904L NO8904 Stainless Steel Plate Sheet Coil
The execution standard for 904L seamless steel pipe is ASTM A240/ASME
904L belongs to austenitic stainless steel， with physical and mechanical properties: density: 8.24g/cm3. Tensile strength: σ B ≥ 520Mpa. Elongation: δ≥ 35%.It has good resistance to spot corrosion and Crevice corrosion， high resistance to stress corrosion cracking， good resistance to intergranular corrosion， good workability and weldability.
904L is a low-carbon austenitic stainless steel that can be used under severe corrosion conditions. It contains 25% nickel and 4.5% molybdenum， and has good resistance to chloride stress corrosion cracking. Compared with 316L and 317L， 904L has excellent corrosion resistance. Due to the addition of Cu， the alloy exhibits excellent corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid.
Common applications include the production and transportation of sulfuric acid， metal pickling in sulfuric acid， papermaking and related industries， and the chemical and pharmaceutical industries.
