Kupangandikupangira zitsulo zachitsulo mu billet ndi nyundo kapena makina okakamiza; Malinga ndi kapangidwe kake, chitsulocho chikhoza kugawidwa kukhala chitsulo cha carbon ndi alloy steel.

(1) Kuwonjezera chitsulo ndi carbon, mankhwala zikuchokera mpweya zitsulo mulinso zinthu monga manganese siliko, sulfure ndi phosphorous, amene sulfure ndi phosphorous ndi zoipa zonyansa. Silico ya manganese ndi chinthu chopangidwa ndi deoxidized chomwe chimawonjezeredwa kuzitsulo za carbon popanga zitsulo. Malinga ndi zomwe zili mu carbon zitsulo, nthawi zambiri zimagawidwa m'magulu atatu awa:
Chitsulo chochepa cha carbon: Zomwe zili ndi carbon ndi 0.04% -0.25%;
Sing'anga mpweya zitsulo: 0,25% -0.55% mpweya;
Mkulu wa carbon zitsulo: mpweya wambiri kuposa 0.55%
(2) aloyi zitsulo ndi kuwonjezera chimodzi kapena zingapo alloying zinthu mu carbon zitsulo ndi chitsulo chotentha zitsulo monga silicon manganese aloyi zinthu kapena zinthu olimba, mulinso zinthu zina aloyi, monga faifi tambala chromium molybdenum vanadium titaniyamu tungsten cobalt zotayidwa zirconium niobium. ndi osowa dziko zinthu etc. Komanso, ena kashiamu aloyi zitsulo lili boroni ndi asafe etc. Zinthu zopanda zitsulo malinga ndi kuchuluka kwa zomwe zili muzitsulo za alloy, zimagawidwa m'magulu atatu awa:

Chitsulo chochepa cha alloy: zonse zomwe zili ndi alloying ndizochepera 3.5%;
Chitsulo chapakati cha aloyi: zonse zomwe zili ndi alloying ndi 3.5-10%;
Chitsulo chachikulu cha alloy: zonse zomwe zili ndi alloying ndizoposa 10%
Malinga ndi kuchuluka kwa zinthu zosiyanasiyana aloyi zili mu aloyi zitsulo, komanso akhoza kugawidwa mu bayinare ternary ndi Mipikisano chinthu aloyi zitsulo kuwonjezera, malinga ndi mitundu ya zinthu aloyi zili zitsulo, akhoza kugawidwa mu manganese chitsulo, chromium chitsulo, Boron chitsulo, silicon chitsulo, manganese chitsulo, chromium manganese chitsulo, molybdenum chitsulo, chromium molybdenum, tungsten vanadium zitsulo ndi choncho
