Product information

Grade: SUS447J1 
SUS447J1 stainless steel (corresponding to the Chinese grade 008Cr30Mo2) is a high-performance ferritic stainless steel in accordance with the Japanese JIS standard. It possesses excellent corrosion resistance and mechanical properties, making it suitable for demanding industrial environments. ‌
Corrosion Resistance
This material achieves significant reduction in intergranular corrosion risk by strictly controlling the carbon (≤0.01%) and nitrogen (≤0.015%) contents. The combination of high chromium (28.5% - 32%) and molybdenum (1.5% - 2.5%) effectively inhibits chloride stress corrosion cracking and pitting corrosion, especially in scenarios such as wastewater treatment with chloride ions and seawater desalination.
Mechanical Properties
The tensile strength of the as-received state is ≥ 450 MPa, the yield strength is ≥ 295 MPa, and the elongation is ≥ 20%; after cold rolling, the tensile strength can reach 600 MPa, while still maintaining an elongation of 15%. It has excellent high-temperature stability, with an anti-tensile strength of ≥ 320 MPa at 600°C and a creep rupture life of up to 100,000 hours (650°C/60 MPa).
Typical Applications
It is mainly used in organic acid production equipment such as acetic acid and lactic acid, as well as in alkali production equipment such as caustic soda (sodium hydroxide) and in scenarios requiring anti-chloride corrosion in the chemical and energy sectors.

Chemical composition 
The chemical composition of SUS447J1 stainless steel is as follows:
‌Carbon (C): ≤ 0.01% ‌
‌Silicon (Si): ≤ 0.40% ‌
‌Manganese (Mn): ≤ 0.40% ‌
‌Sulfur (S): ≤ 0.020% ‌
‌Phosphorus (P): ≤ 0.030% ‌
‌Chromium (Cr): 28.5% - 32.0% ‌
‌Molybdenum (Mo): 1.50% - 2.50% ‌
‌Copper (Cu): ≤ 0.20%
‌Nickel (Ni): ≤ 0.50% ‌
‌Nitrogen (N): ≤ 0.015% ‌
This steel type belongs to high-purity ferritic stainless steel. Through ultra-low carbon, nitrogen design and high chromium-molybdenum composition, it combines corrosion resistance, stress corrosion cracking resistance and thermal stability, and is widely used in pharmaceutical equipment, chemical containers and other harsh environments.
