Mechanical properties Tensile strength:

 

σb≥690Mpa Elongation: δ≥35%

 

 

 

 

 

Advantages

1. Corrosion resistance is better than 316L and 317L stainless steel, which can be exposed to the atmospheric environment above the sea for a long time. In the quiet seawater environment, corrosion resistance is slightly better than Monel 400 alloy.

 

2. Double the tensile strength of 304 and 316 stainless steel.

 

3. In the environment of thermal chloride, it will be affected by stress corrosion cracking, and its anti-cracking performance is between 304 and 316.

 

4. Excellent mechanical performance at 629℃

 

5. Good mechanical properties and extremely low permeability under low temperature conditions.
