麻豆视频445M
Ni-free high corrosion-resistance 22Cr 1Mo stainless steel
<Composition> 22Cr - 1Mo - Nb - ultra-low (C, N) (equiv. to SUS445J1)
comparison of corrosion resistance
Weldability
Corrosion resistance
- Higher chromium content of 22% and addition of 1% molybdenum for exellent corrosion resistance equivalent to SUS316 and SUS444.
- No risk of stress corrosion cracking.
- Totally free of nickel, so cost is not impacted by the price fluctuations of nickel.
- Designed to be eco-friendly and economical, by limiting the quantity of added molybdenum compared to SUS316 and SUS444.
Applications
Hot water heater body, water storage tanks, solar water heaters, hot water dispensers, roofing materials, architectural exteriors, heat exchangers, food equipment
