Hlau tsis xeb 422, X20CrMoWV12-1, 1.4935, SUH 616, UNS 42200, ASTM A437 Qib B4B martensitic creep resistant stainless hlau ntxiv cov hlau hnyav alloying ntsiab lus muab nws lub zog zoo thiab temper tsis kam ntawm qhov kub siab dua txog li 1200 F, Chrome-nickel hlau nrog lub qauv austenitic nrog carbides. Alloying ntxiv ntawm molybdenum, vanadium thiab tungsten ua rau kom muajkub yaj. Zoo ib yam li 410 stainless no qib muaj peev xwm ua kom sov kho rau ntau qib sib txawv. Vim yog qhov kub tsis kam, cov hlau no feem ntau siv rau hauvkev lag luam tsim hluav taws xob raws li cov khoom siv pa thiab roj turbine lossis ntau yam khoom siv kub siab, feem ntau yog cov hniav turbine thiab cov khoom siv txuas. B50A125E yog cov hlau uas tiv taus Creep nrov uasyog hardened thiab tempered kom muab kev ntseeg siab tseem ceeb hauv kev siv kub siab nrog rau qhov kub thiab txias tas mus li ntawm 580 ℃., 422 Stainless, UNS S42200, B50A, AISI 616,AMS 5655, ASTM A 565 GRD 616, MIL S 861, B50A125, B50A951A1, BS 970 442S19, EN61 Los ntawm Saky Steel.
