Ukuqulunqakukwenziwa kwentsimbi yentsimbi kwibillet ngehamile okanye ngomatshini woxinzelelo; Ngokokwakheka kweekhemikhali, intsimbi inokwahlulwa ibe yintsimbi yecarbon kunye nealloy steel.

(1) Ukongeza kwi-iron kunye nekhabhoni, ukubunjwa kweekhemikhali ze-carbon steel nazo ziqulethe izinto ezifana ne-manganese silico, isulfure kunye ne-phosphorus, phakathi kwayo isulfure kunye ne-phosphorus yinto engcolileyo eyingozi. I-Manganese silico yi-deoxidized element eyongezwe kwi-carbon steel kwinkqubo yokwenza intsimbi. Ngokomxholo wekhabhoni owahlukileyo kwintsimbi yekhabhoni, ihlala yohlulwe ngokwezi ntlobo zintathu zilandelayo:
Insimbi ye-carbon ephantsi: Umxholo wekhabhoni ngu-0.04% -0.25%;
Intsimbi yekhabhoni ephakathi: 0.25% -0.55% umxholo wekhabhoni;
Intsimbi yekhabhoni ephezulu: umxholo wekhabhoni omkhulu kune-0.55%
(2) ingxubevange yentsimbi yongeza enye okanye ezininzi zezinto ezixubekileyo kwikhabhoni yentsimbi kunye nentsimbi epholileyo efana nentsimbi enje iqulathe zombini njenge-silicon manganese ingxubevange izinto okanye izinto eziqinileyo, ikwaqulathe ezinye izinto ezixubekileyo, ezifana nickel chromium molybdenum vanadium titanium tungsten cobalt aluminiyam zirconium niobium kunye nentsimbi nitrogen enqabileyo kunye nentsimbi ye-nitrogen enqabileyo njl. Izinto ezingezizo ezentsimbi ngokwesixa somxholo we-alloy element kwintsimbi, zahlulwe ngokwazi ndidi zintathu zilandelayo:

Insimbi ye-alloy ephantsi: umxholo wento edibeneyo yokudibanisa ingaphantsi kwe-3.5%;
Insimbi ye-alloy ephakathi: umxholo we-alloying element ngu-3.5-10%;
Intsimbi ephezulu ye-alloy: umxholo wento ehlanganisiweyo iyonke ingaphezulu kwe-10%
Ngokwenani lezinto ezahlukeneyo zealloyi eziqulethwe kwintsimbi yealloyi, nazo zinokwahlulwa zibe yintsimbi yokubini kunye ne-multi-element alloy steel ukongeza, ngokweentlobo zezinto eziqulethwe yintsimbi, zinokwahlulwa zibe yintsimbi yemanganese, intsimbi yechromium, intsimbi ye-boron, isinyithi sesilicon, intsimbi yemanganese, intsimbi ye-chromium manganese, isinyithi se-molybdenum, intsimbi ye-molybdenum, isinyithi se-molybdenum, i-molybdenum. njalo njalo
