1.Tool steel imhando yesimbi yakagadzirwa kuti ishandiswe kune zvakasiyana-siyana zvezvishandiso uye michina yakagadzirwa.Kuumbwa kwayo kwakagadzirirwa kupa musanganiswa wekuoma, simba, uye kupfeka kuramba.Maturusi emidziyo anowanzo aine huwandu hwakawanda hwekabhoni (0.5% kusvika 1.5%) uye zvimwe zvinosanganiswa zvinhu zvakaita sechromium, tungsten, molybdenum, vanadium, uye manganese.Zvichienderana nekushandiswa, masimbi emidziyo anogona zvakare kunge aine akasiyana ezvimwe zvinhu, senge nickel, cobalt, uye silicon.
2.Iyo chaiyo kusanganiswa kwealloying zvinhu zvinoshandiswa kugadzira simbi yemidziyo ichasiyana zvichienderana nezvinodiwa uye kushandiswa.Masimbi emidziyo anonyanya kushandiswa anotsanangurwa sesimbi inomhanya-mhanya, simbi inotonhora, uye simbi inopisa.
