Incazelo yensimbi ekhethekile ayichazwanga ngokucacile emhlabeni wonke, futhi ukuhlukaniswa kwezibalo zensimbi ekhethekile emazweni ahlukene akufani.
Imboni ekhethekile yensimbi eChina ihlanganisa iJapan neYurophu.
Ihlanganisa izinhlobo ezintathu zensimbi yekhwalithi ephezulu ye-carbon, i-alloy steel, ne-high-alloy steel.
Ivamise ukuvulwa njengensimbi yesakhiwo sensimbi yekhwalithi ephezulu, i-alloy structural steel, i-carbon tool steel, i-alloy tool steel, insimbi yethuluzi lesivinini esikhulu, i-bearing steel, i-spring steel (i-carbon spring steel ne-alloy spring steel), insimbi engashi. kanye nensimbi engagqwali.
Ngenxa yokuthi ama-alloys aphezulu okushisa kanye nama-alloys amahle akhiqizwa ezigayweni ezikhethekile zensimbi, lezi zingxube ezimbili nazo zifakwe ekubalweni kwamaqembu ensimbi akhethekile. Esigabeni sensimbi esikhethekile, ngaphandle kwensimbi yesakhiwo sekhabhoni yekhwalithi ephezulu, insimbi yensimbi yensimbi ye-carbon ne-carbon spring steel, okusele ama-alloy steels, ahlanganisa cishe u-70% wezinsimbi ezikhethekile.
Njengamanje, kunamabanga acishe abe ngu-2,000 ensimbi ekhethekile emhlabeni, izinhlobo ezingaba ngu-50,000 kanye nokucaciswa kwawo, kanye namakhulu ezindinganiso zokuhlola.
