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%
