Inkcazo yensimbi ekhethekileyo ayichazwanga ngokucacileyo ngamazwe ngamazwe, kwaye ulwahlulo lokubala lwensimbi ekhethekileyo kumazwe ahlukeneyo alufani.
Ishishini elikhethekileyo lentsimbi eTshayina ligubungela iJapan neYurophu.
Iquka iintlobo ezintathu zentsimbi ye-carbon ephezulu, i-alloy steel, kunye ne-high-alloy steel.
Ivulwa ngokubanzi njengentsimbi ekumgangatho ophezulu wekhabhoni yentsimbi, intsimbi yokwakha ingxubevange, intsimbi yesixhobo sekhabhoni, intsimbi yentsimbi, isixhobo esinesantya esiphezulu, intsimbi yentsimbi, intsimbi yasentwasahlobo (intsimbi yentsimbi yekhabhoni kunye nentsimbi yasentwasahlobo), ukumelana nobushushu. kunye nentsimbi engenasici.
Ngenxa yokuba i-alloys ephezulu yokushisa kunye ne-alloys emihle iveliswa kwiintsimbi ezikhethekileyo zetsimbi, ezi zimbini zifakwe ekubalweni kwamaqela akhethekileyo ensimbi. Kwinqanaba elikhethekileyo lensimbi, ngaphandle kwekhwalithi ephezulu ye-carbon structural steel, i-carbon tool steel kunye ne-carbon spring steel, ezinye ziyi-alloy steels, ezithatha malunga ne-70% yeentsimbi ezikhethekileyo.
Okwangoku, kukho phantse ama-2,000 amabakala ensimbi ekhethekileyo emhlabeni, malunga neentlobo ze-50,000 kunye neenkcukacha, kunye namakhulu emigangatho yokuhlola.
