Ngokungeza izinto ezifana ne-tungsten, i-molybdenum kanye ne-vanadium, ubunzima bungafinyelela ku-90-95HSD, kanti impilo yokusebenza ingama-2-3 izikhathi kunezindandatho ze-Cr5 ezijwayelekile. Ibonisa ubunzima obuphezulu, ukumelana nokugqoka okuphezulu kanye nokuzinza okuhle kokushisa. Insimbi esheshayo iqukethe inani elikhulu lezinto zokuhlanganisa ezifana ne-tungsten, i-molybdenum, i-chromium kanye ne-vanadium, zakha ama-carbides ayinkimbinkimbi, okwenza ikwazi ukugcina ubunzima obuphezulu namandla ezingeni eliphezulu lokushisa futhi ibekezelele izinga eliphezulu lokugijima namandla okugijima.
2. Umkhawulo wokusetshenziswa: Ikakhulukazi isetshenziswa ekugudlweni kwemikhiqizo ephakeme-ukunemba kanye nekhono eliphezulu (njengensimbi yemoto enamandla aphezulu), njengensimbi ye-strip ethinnyi kakhulu, insimbi ye-alloy enembile, njll. Ikhethekile ekugudlweni okusheshayo nasekugudlweni kwezinto ezinzima ukujika.
