Uamea u'amea 422, X20CrMoWV12-1, 1.4935, SUH 616, UNS 42200, ASTM A437 Vasega B4B fa'ama'i fetolofi u'amea uamea fa'aopoopo mea fa'afefiloi u'amea mamafa e maua ai le malosi lelei ma le ita i le maualuga o le vevela e o'o atu i le 1200 F, fa'apipi'i austenitic ta'avale. Alloying faaopoopoga o molybdenum, vanadium ma tungsten faateleina levevela vevela. E tutusa ma le 410 stainless lenei vasega o loʻo i ai le malosi e faʻafefe ai le vevela i le tele o tulaga malosi eseese. Ona o le tete'e o le ita, e masani ona fa'aogaina lenei u'amea i lemaketi gaosiga eletise e pei o vaega ausa ma gas turbine po'o isi vaega vevela maualuga, aemaise lau turbine ma fasteners. B50A125E o se lauiloa Creep tetee sila leae faʻamaʻa ma faʻafefe e tuʻuina atu ai le faʻalagolago tele i le maualuga o le vevela faʻatasi ai ma le faʻatapulaʻaina o le vevela faʻaauau i luga ole 580℃., 422 Stainless, UNS S42200, B50A, AISI 616,AMS 5655, ASTM A 565 GRD 616, MIL S 861, B50A125, B50A951A1, BS 970 442S19, EN61 Mai Saky Steel.
