Ho qapake ho etsoa ha tšepe ea tšepe ka har'a billet ka hamore kapa mochini oa khatello; Ho ea ka sebopeho sa lik'hemik'hale, tšepe e ka aroloa ka tšepe ea carbon le alloy steel.

(1) Ho phaella ho tšepe le k'habone, lik'hemik'hale tsa carbon steel li boetse li na le likarolo tse kang silico ea manganese, sebabole le phosphorus, tseo har'a tsona sebabole le phosphorus e leng litšila tse kotsi.Manganese silico ke ntho e nang le deoxidized e kentsoeng ho tšepe ea carbon nakong ea ho etsa tšepe.Ho ea ka likarolo tse fapaneng tsa khabone ka har'a tšepe ea carbon, hangata e arotsoe ka mefuta e meraro e latelang:
Tšepe e tlaase ea carbon: Likahare tsa carbon ke 0.04% -0.25%;
Bohareng ba carbon steel: 0.25% -0.55% carbon content;
High carbon steel: dikahare tsa carbon tse fetang 0.55%
(2) motsoako oa tšepe o kenyelletsa ntho e le 'ngoe kapa tse' maloa tsa motsoako ka tšepe ea carbon le tšepe e halefileng e na le likarolo tse ling tsa silicon manganese alloy kapa likarolo tse tiileng, hape e na le likarolo tse ling tsa motsoako, joalo ka nickel chromium molybdenum vanadium titanium tungsten cobalt aluminium zirconium niobium. le lintho tse sa tloaelehang tsa lefatše joalo-joalo Ho phaella moo, tšepe e 'ngoe ea tšepe e nang le khalsiamo e na le boron le naetrojene joalo-joalo.

Tšepe ea alloy e tlase: kakaretso ea likarolo tsa alloying e ka tlase ho 3.5%;
Tšepe ea alloy e bohareng: kakaretso ea motsoako oa motsoako ke 3.5-10%;
Tšepe e phahameng ea alloy: kakaretso ea likarolo tsa alloying e feta 10%
Ho ea ka palo ea likarolo tse fapaneng tsa alloy tse nang le tšepe ea alloy, le tsona li ka aroloa ka tšepe ea ternary le multi-element alloy, ho ea ka mefuta ea lisebelisoa tsa alloy tse nang le tšepe, e ka aroloa ka tšepe ea manganese, tšepe ea chromium, boron tšepe, silicon tšepe, manganese tšepe, chromium manganese tšepe, molybdenum tšepe, chromium molybdenum, tungsten vanadium tšepe joalo-joalo.
