Kukanganisikandiko kukanganisika kwesimbi kungangoita billet ine nyundo kana kumanikidza muchina; zvinoenderana nemakemikari mamiriro, simbi inogona kukamurwa kuita carbon simbi uye alloy simbi

. Manganese silico chinhu chakashata chakawedzerwa kuCarbon Steel mune maitiro ekunzwa. Zvinoenderana neyakasiyana carbon zvirimo muCarbon Simbi, inowanzo kukamurwa mumhando dzinotevera mitatu:
Low Carbon Steel: Carbon Zviri Mukati 0.04% -0.25%;
Pakati pekaroni simbi: 0.25% -0.55% kabhoni yezvinyorwa;
Yakakwira kabhoni simbi: kabhoni zvemukati zvakakura kupfuura 0.55%
(2) Alloy Alloy inowedzera imwe kana akati wandei ezvinyorwa zvebhokisi uye nehasha dzakadai simbi molium Alloy Simbi ine Boron uye nitrogen E,S. NITROGE zvinhu zvinoenderana nehuwandu hwehuwandu hwehuwandu hwehukama hwehusimbi, hwakakamurwa muzvikamu zvitatu zvitatu:

Low Alloy Simbi: Iyo yakazara yakakwana element element yezvinyorwa isingasviki 3.5%;
Pakati peiyo Alloy Simbi: Iyo Yakazara Allying Element Zvemukati ndeye 3.5-10%;
Yakakwira Alloy Simbi: Iyo yakazara yakanyanya kujairika element yezvinyorwa zvinopfuura gumi muzana
Zvinoenderana nehuwandu hwezvakasiyana zvezviyero zvirimo mune zvekuswera, zvakare hunogona kukamurwa kuita binary ternary, chroron simbi, chroron simbi, chronese simbi, chronei Molybdenum, Tungsten Vanadium Steel uye zvichingodaro
