I-1.Insimbi yensimbi luhlobo lwensimbi yensimbi eyenzelwe ukusetyenziselwa izixhobo ezahlukeneyo kunye namacandelo omatshini.Ukubunjwa kwayo kulungiselelwe ukubonelela ngokudityaniswa kobunzima, amandla, kunye nokuxhatshazwa kokugqoka.Iintsimbi zesixhobo ngokuqhelekileyo ziqulethe ixabiso eliphezulu lekhabhoni (0.5% ukuya kwi-1.5%) kunye nezinye izinto ze-alloying ezifana ne-chromium, i-tungsten, i-molybdenum, i-vanadium, kunye ne-manganese.Ngokuxhomekeke kwisicelo, iintsimbi zesixhobo zinokuqulatha ezinye izinto ezahlukeneyo, njenge-nickel, i-cobalt, kunye nesilicon.
2.Ukudibanisa okuthe ngqo kwezinto ezisetyenziselwa ukwenza isixhobo sensimbi kuya kuhluka ngokuxhomekeka kwiipropati ezifunwayo kunye nesicelo.Ezona ntsimbi zisetyenziswa ngokuqhelekileyo zihlelwa njengentsimbi enesantya esiphezulu, intsimbi yokusebenza ebandayo, kunye nentsimbi yokusebenza eshushu.”
