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.
