Cov khoom siv nruab nrab thiab qis qis-cov hlau tsis muaj zog feem ntau muaj cov tshuaj lom neeg xws li silicon, manganese, chromium, molybdenum, vanadium, tungsten, npib tsib xee, titanium, boron, tooj liab, tsis tshua muaj ntiaj teb, thiab lwm yam. Cov ntaub ntawv ntawm ntau qhov nruab nrab thiab loj pob zeb hauv Tebchaws Meskas yog ua los ntawm chromium-molybdenum-silicon-manganese lossis chromium-molybdenum steel. Cov pob zeb sib tsoo feem ntau hauv Asmeskas yog ua los ntawm nruab nrab- thiab siab -carbon chromium-molybdenum steel. Rau workpieces ua hauj lwm nyob rau hauv abrasive hnav tej yam kev mob ntawm kub siab (xws li 200 ~ 500 degree) los yog workpieces raug rau saum npoo kom kub ntau dua vim kev sib txhuam ntawm tshav kub, alloy hnav-resistant steels xws li chromium-molybdenum-vanadium, chromium{18}}molybdenum-vanadium-nickel lossis chromium-molybdenum-vanadium-tungsten tuaj yeem siv tau.
