super duplex stainless hlau astm qib
Super duplex stainless steel refers to duplex steel with PREN>40, containing 25% Cr and high molybdenum (>3.5%) thiab nitrogen siab (0.22% ~ 0.30%). Cov qib tseem ceeb yog UNS S32550 (UR52N+), S32750 (SAF 2507) thiab S32760 (Zeron 100) tau tsim los ntawm cov tuam txhab xws li Fabkis CLI, Swedish SANDVIK thiab British MATER + PLATT feem. Lawv cov ntaub ntawv deformable tau tshwm sim nyob rau xyoo 1990 thiab 1991, thiab nkag mus rau hauv kev lag luam hauv xyoo tas los. Qhov sib xyaw ntawm peb cov hlau no zoo sib xws, qhov sib txawv nyob hauv cov ntsiab lus ntawm tungsten thiab tooj liab.
