Kuletsandikungoyikidwa pazachitsulo ku billet ndi makina a nyuzi kapena opanikizika; malinga ndi kapangidwe ka mankhwala, zitsulo zitha kugawidwa kukhala chitsulo chachitsulo ndi chitsulo

. Silico ya Manganese ndi chinthu chopangidwa ndi kateya chowonjezeredwa ndi chitsulo cha kaboni pokonzekera kukhazikitsa. Malinga ndi zomwe zili mu kaboni mosiyanasiyana mu chitsulo cha kaboni, nthawi zambiri limagawika m'mitundu itatu:
Chitsulo chotsika: Mitundu ya carbon ndi 0.04% -0.25%;
Pakatikati pa mpweya wabwino: 0.25% -0.55% kaboni.
Storm Carbon Steel: Mitundu ya Carbon wamkulu kuposa 0,55%
. ndi zowonjezera zapadziko lapansi zambiri. Kuphatikiza apo, calciamu zina za callon ndi Nitrogen zida zonse ziwiri za zitsulo, zimagawidwa m'magulu atatu otsatirawa:

Chitsulo chotsika: Zomwe zimapangitsa kuti zikhale zosakwana 3.5%;
Mitundu ya Internant Anoy: Kuyatsira kwathunthu kwazinthu ndi 3.5-10%;
Zithunzi zapamwamba za alloy: zomwe zimapangitsa kuti zinthu zonse ziziposa 10%
Malinga ndi kuchuluka kwa zinthu zosiyanasiyana za Aloya zomwe zili mu chitsulo chachitsulo, komanso titha kugawidwa kukhala chitsulo cholumikizira ndi mitundu yambiri ya ilooy zophatikizika zomwe zili mu chitsulo, zitha kugawidwa mu chitsulo cha mangane, chromium slide, boron steel, silicon steel, manganese steel, chromium manganese steel, molybdenum steel, chromium molybdenum, tungsten vanadium steel and so on
