Plus molybdenum, corrosion resistance than 304 strong, especially for seawater and chemical media, more corrosion resistance and pitting resistance.

Note:

1) If the nickel content is less than 8%, the minimum content of manganese must be 5%
2) When the nickel content is more than 8%, the minimum content of copper is not limited
3) If the chromium content is less than 17%, then the minimum nickel content of 12%
4) For the maximum 0.03% carbon content of austenitic stainless steel, nitrogen content of up to 0.22
5) For larger diameter products, in order to achieve the specified mechanical properties in the manufacturer\'s instructions, may have a higher carbon content, but martensitic steel should not exceed 0.12%
