Cov yeeb nkab hlau alloy feem ntau yog siv rau hauv cov chaw tsim hluav taws xob, lub zog nuclear, lub boiler siab, lub tshuab cua sov kub siab thiab lub tshuab cua sov dua thiab lwm yam kav dej siab thiab kub siab thiab cov khoom siv, nws yog ua los ntawm cov hlau carbon zoo, cov hlau alloy thiab cov hlau tsis xeb uas tiv taus cua sov, los ntawm kev dov kub (extrusion, expansion) lossis dov txias (rub).

Qhov zoo tshaj plaws ntawm cov yeeb nkab Alloy Steel yog tias nws tuaj yeem rov ua dua 100%, uas yog raws li lub teb chaws txoj kev tiv thaiv ib puag ncig, txuag hluav taws xob thiab txuag cov peev txheej. Txoj cai hauv teb chaws txhawb kom nthuav dav ntawm daim ntawv thov ntawm cov yeeb nkab siab Alloy. Tam sim no, kev siv cov yeeb nkab alloy hauv Suav teb tsuas yog ib nrab ntawm tag nrho cov hlau siv hauv cov teb chaws tsim kho. Kev nthuav dav ntawm kev siv cov yeeb nkab alloy muab qhov chaw dav dua rau kev txhim kho kev lag luam. Raws li kev tshawb fawb ntawm pawg kws tshaj lij ntawm cov yeeb nkab alloy ceg ntawm Tuam Tshoj Tshwj Xeeb Steel Association, qhov kev thov rau cov yeeb nkab alloy siab hauv Suav teb yuav nce ntxiv 10-12% txhua xyoo yav tom ntej. Cov yeeb nkab alloy yog cov yeeb nkab hlau raws li kev tsim khoom ntawm cov khoom siv (uas yog, cov khoom siv) los txhais, raws li lub npe qhia yog cov yeeb nkab alloy; Thiab cov yeeb nkab seamless yog cov yeeb nkab hlau raws li cov txheej txheem tsim khoom (seamless) los txhais, sib txawv ntawm cov yeeb nkab seamless yog cov yeeb nkab seam, suav nrog cov yeeb nkab vuam seam ncaj thiab cov yeeb nkab kauv.

Cov khoom siv ntawm cov hlau alloy yog roughly li nram no:

16-50Mn, 27SiMn, 40Cr, 12-42CrMo, 16Mn, 12Cr1MoV, T91, 27SiMn, 30CrMo, 15CrMo, 20G, Cr9Mo, 10CrMo910, 15Mo3, 15CrMoV, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, thiab lwm yam.
