Intsimbi engagqwaliyo 422, X20CrMoWV12-1, 1.4935, SUH 616, UNS 42200, ASTM A437 Grade B4B martensitic stainless resistant creep steel ezongezelelweyo izinto ze-alloying zesinyithi esinzima ezisinika amandla amahle kunye nokumelana nobushushu kumaqondo obushushu aphezulu ukuya kuthi ga kwi-1200 F, intsimbi ye-Chrome-nickel enesakhiwo se-austenitic esinee-carbides. Ukongezwa kwe-alloying ye-molybdenum, i-vanadium kunye ne-tungsten kwandisaubushushu bokunyibilika. Njenge-stainless 410, olu hlobo lunamandla okulungiswa ngobushushu kumanqanaba ahlukeneyo amandla. Ngenxa yokumelana nobushushu, olu hlobo lwentsimbi lusetyenziswa rhoqo kwi-imakethi yokuvelisa umbane njengezixhobo zeturbine zomphunga kunye negesi okanye ezinye izinto ezishushu kakhulu, ikakhulu iiblade zeturbine kunye neziqhoboshi. I-B50A125E yintsimbi edumileyo enganyangekiyo neCreep esetyenziswa kakhulu.iqinisiwe kwaye ithambile ukuze inike ukuthembeka okubalulekileyo kwizicelo zobushushu obuphezulu kunye nomda oqhelekileyo wobushushu obuqhubekayo obuphezulu obuyi-580℃., 422 Stainless, UNS S42200, B50A, AISI 616,I-AMS 5655, ASTM A 565 GRD 616, MIL S 861, B50A125, B50A951A1, BS 970 442S19, EN61 Ukusuka kwiSaky Steel.
