Stainless Steel (Super) Duplex Steel

Duplex stainless steel means that ferrite and austenite each account for about 50%, generally the content of less phase also needs to reach at least 30% of stainless steel,

Cr content is 18% to 28%, Ni content is 3% to 10% , containing Mo, Cu, N and other alloying elements. Duplex stainless steel not only has the characteristics of

both austenitic stainless steel and ferritic stainless steel materials, but also has high strength, chloride stress corrosion resistance, pore corrosion resistance, pit pitting ability,

such as: S31803 material resistance to pitting ( PREN32-33)

The S32750 material is resistant to pitting (PREN>40). Widely used in offshore oil, seawater desalination, chemical pipelines, reactors, heat exchangers, etc.

Material characteristics

  1. Balanced two organizations – with a balanced two-phase organization with excellent overall performance.

2, Good corrosion resistance – excellent resistance to pitting, chloride corrosion resistance.

3, Excellent mechanical properties – yield strength is about 2 times that of ordinary austenitic stainless steel,

the allowable stress is about 1.5 times that of ordinary austenitic stainless steel.

4, High and low temperature environment adaption – use temperature -50 °C ~ 300 °C
