Duplex Stainless Steel

Super duplex stainless steel with PREN>40, containing 25% Cr and high molybdenum (>3.5%), high nitrogen (0.22%~0.30%) duplex steel, the main grade is UNS S32550 (UR52N+) developed by French CLI company , S32750 (SAF 2507) developed by the Swedish SANDVIK company and S32760 (Zeron 100) developed by the British company MATER+PLATT are the main grades. Their deformable materials came out in 1990 and 1991 and entered the market in recent years. The composition of these three grades of super duplex stainless steel is similar, but the difference lies in the content of tungsten and copper.

2205 duplex stainless steel plate

2507 duplex stainless steel plate

  • Duplex Stainless Steel 2205 has twice the compressive strength of austenitic stainless steel, allowing designers to reduce their weight compared to 316L and 317L. The 2205 alloy is especially suitable for use in the -50° F/ + 600° F temperature range and can be used for lower temperatures under severe restrictions.
  • 2507 duplex stainless steel plates are classified according to their chemical composition and can be classified into four types: Cr18 type, Cr23 (excluding Mo) type, Cr22 type and Cr25 type.
