Forgingndiko kuumbwa kwesimbi ingot mubillet nesando kana muchina wekumanikidza; Zvinoenderana nekugadzirwa kwemakemikari, simbi inogona kukamurwa kuita kabhoni simbi uye alloy simbi.

(1) Kuwedzera kune iron uye kabhoni, iyo kemikari yekabhoni simbi inewo zvinhu zvakaita semanganese silico, sarufa uye phosphorus, pakati peiyo sarufa uye phosphorus inokuvadza tsvina. Manganese silico i deoxidized element inowedzerwa ku carbon steel mukuita simbi. Zvinoenderana neyakasiyana kabhoni yemukati mune kabhoni simbi, inowanzo kupatsanurwa mumhando nhatu dzinotevera:
Low carbon steel: Carbon content is 0.04% -0.25%;
Medium carbon steel: 0.25% -0.55% carbon content;
Yakakwira kabhoni simbi: kabhoni yemukati inopfuura 0.55%
(2) simbi alloy inowedzera imwe kana akati wandei ealloying element mucarbon simbi uye simbi yakapfava simbi yakadaro ine zvese sesilicon manganese alloy element kana solid elements, inewo zvimwe zvinhu zvinosanganisa, senge nickel chromium molybdenum vanadium titanium tungsten cobalt aluminium zirconium niobium. uye zvisingawanzoitiki zvepasi zvinhu etc. Mukuwedzera, imwe calcium alloy simbi ine boron nenitrogen etc. Nonmetal elements maererano nehuwandu hwehuwandu hwehuwandu hwealloy element musimbi, yakakamurwa muzvikamu zvitatu zvinotevera:

Yakaderera alloy simbi: iyo yakazara alloying element yemukati iri pasi pe3.5%;
Medium alloy simbi: iyo yakazara alloying element yemukati ndeye 3.5-10%;
Yakakwira alloy simbi: iyo yakazara alloying element yemukati inodarika 10%
Zvinoenderana nehuwandu hweakasiyana alloy zvinhu zviri mualloy simbi, zvakare inogona kukamurwa kuita mabhinari ternary uye akawanda-element alloy simbi mukuwedzera, zvichienderana nemhando dzealloy zvinhu zviri musimbi, zvinogona kukamurwa kuita manganese simbi, chromium simbi, boron simbi, nesilicon simbi, manganese simbi, chromium manganese simbi, molybdenum simbi, chromium molybdenum, tungsten vanadium simbi uye zvichingodaro.
