- Corrosion resistance: Excellent in non-oxidizing acids like sulfuric acid, acetic acid, formic acid, and phosphoric acid
- Pitting corrosion resistance: Performs well in neutral chloride ion media
- Resistance to crevice corrosion and stress corrosion: Suitable for harsh corrosive environments
- Density: 8.0 g/cm3
- Melting point: 1300-1390 ℃
- Tensile strength: σ b ≥ 520Mpa
- Elongation rate: δ ≥ 35%
The low carbon content (≤0.020%) prevents carbide precipitation during heat treatment and welding, eliminating intergranular corrosion risk. The high chromium-nickel-molybdenum content with copper addition enables passivation even in reducing environments like sulfuric and formic acids.
Operating temperature reaches 40°C in 0-98% sulfuric acid and shows excellent resistance in 0-85% phosphoric acid. While limited to 1-2% concentration in hydrochloric acid, it outperforms conventional stainless steels. The high nickel content reduces corrosion in pits/crevices and provides exceptional stress corrosion cracking resistance in chloride solutions, concentrated hydroxide, and hydrogen sulfide-rich environments.
