Bir aan miridh lahayn 422, X20CrMoWV12-1, 1.4935, SUH 616, UNS 42200, ASTM A437 Heerka B4B ee birta aan miridh lahayn ee u adkaysta martensitic creep steep steel oo leh walxo bir culus oo dheeraad ah oo siiya xoog wanaagsan iyo iska caabin heerkulka heerkulka sare ilaa 1200 F, birta Chrome-nickel oo leh qaab-dhismeed austenitic ah oo leh carbides. Ku darista walxaha molybdenum, vanadium iyo tungsten waxay kordhisaaheerkulka dhalaalka. Sida 410 oo ah birta aan lahayn, heerkani wuxuu awood u leeyahay in lagu daaweeyo kulaylka heerar xoog oo kala duwan. Sababtoo ah iska caabbinta heerkulka, daawadan waxaa badanaa loo isticmaalaa gudahasuuqa korontada oo ah qaybo ka mid ah marawaxadaha uumiga iyo gaaska ama qaybo kale oo kuleyl sare leh, gaar ahaan daabyada marawaxadaha iyo qalabka lagu xidho. B50A125E waa bir caan ah oo u adkaysta creep kaas oowaa la adkeeyaa oo la hagaajiyaa si loo siiyo isku halayn muhiim ah codsiyada heerkulka sare leh oo leh heer kul hawlgal oo joogto ah oo caadi ah oo ah 580℃., 422 Aan miridh lahayn, UNS S42200, B50A, AISI 616,AMS 5655, ASTM A 565 GRD 616, MIL S 861, B50A125, B50A951A1, BS 970 442S19, EN61 Laga soo bilaabo Saky Steel.
