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%
. uye zvisingawanzo zvepasi zvinhu nezvimwe.

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 zvezvigadzirwa zvebhandi Boron Steel, Silishon Steel, Manganese Steel, Chromium Manganese Steel, Molybdenum Simbi, Chromium Molybdenum, Tungsten Vanadium Steel uye zvichingodaro
