Let me show you about S32750 material

S32750 material is a super duplex stainless steel designed for applications requiring excellent strength and corrosion resistance.

S32750 alloy contains 25% chromium, 4% molybdenum and 7% nickel. This high molybdenum, chromium and nitrogen content leads to excellent resistance to chloride pitting and crevice corrosion. The dual phase structure makes S32750 excellent resistance to chloride stress corrosion cracking.
