- Cov pa roj carbon steel: Cov qib carbon structural steel yog Q235A (F, b), Q235B (F, b), Q235C, thiab Q235D.Cov kev xav tau zoo ntawm cov qib no tau txhim kho nyob rau hauv kev txiav txim.Cov khoom txheem yog GB700.
- Cov pa roj carbon zoo siab: Cov sawv cev thiab cov cai ntawm cov pa roj carbon zoo yuav tsum ua raws li GB 221. Cov kev cai rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov pa roj carbon zoo yog muab rau hauv GB699 tus qauv.Cov txheej txheem teev 31 qib ntawm cov khoom siv ntawm 08F, 10F, 15F, 08, 10, 15, 20, 25, ····, 70Mn, Feem ntau siv cov qib seamless steel yeeb nkab thiab alloy steel yeeb nkab yog 08, 10 thiab 20. 08 thiab 10 steels feem ntau yog siv los ua hlau gaskets vim lawv cov ntsiab lus carbon tsawg, tsis tshua muaj hardness thiab zoo plasticity.20 steel feem ntau yog siv rau cov kav dej thiab fittings, GB 8163, GB 9948, GB 6479, GB 3087, GB 5310 thiab lwm yam qauv muab cov khoom tsim los ntawm cov khoom siv zoo carbon steel steel kav, uas feem ntau siv steel yeeb nkab qauv rau siab. Cov kav dej GB 710, GB 711, GB 713, GB 5681, GB 6654 thiab lwm yam qauv muab cov khoom tsim nyog ntawm cov pa roj carbon zoo, uas feem ntau yog siv cov qauv steel phaj rau cov kav dej siab.Thaum lub sij hawm xaiv, cov khoom tsim cov khoom tsim nyog ntawm cov pa roj carbon zoo hauv GB 12225, GB 12228 thiab lwm yam qauv yuav tsum tau txiav txim siab raws li nws daim ntawv thov.
- Cov cuab yeej hlau: T7 thiab T8 feem ntau yog siv rau kev tsim cov cua xaiv thiab xuas nrig ntaus ntawm stamping tuag, thiab T10 thiab T11 yog siv rau kev tsim cov reamers, thiab lwm yam.
- Alloy steel: Muaj ntau hom hlau alloy nrog dav siv.Nyob rau hauv pipeline engineering, stainless hlau thiab tsis tshua muaj alloy steel, quenched thiab tempered steel, kub resistant steel thiab tsis kub steel yog dav siv.
