Muaj ntau ntau qib ntawm cov hlau rods, thiab cov qib sib xws yog Q195, Q215, Q235, Sae1008, Sae1006 thiab lwm yam. Cov xov hlau no feem ntau yog siv rau hauv kev tsim kho, tshuab thiab hluav taws xob kev lag luam, xws li kev tsim cov hlua khi, hlau mesh, xov hlau thiab cables.

1022, tseem hu ua AISI 1022 lossis SAE 1022, yog cov khoom siv carbon steel.

Kev siv cov hlau rods feem ntau yog categorized rau ob hom: ib qho rau cov khoom siv hauv tsev thiab lwm yam rau cov khoom siv raw rau hlau kos duab.

Hlau pas nrig rau lub tsev belongs rau ib tug me me txoj kab uas hla profiled steel los yog kub dov steel hlau, txoj kab uas hla feem ntau yog siv ntawm 5-22 hli.

Hlau pas nrig rau kev tsim kho yog ib hom kub dov puag ncig steel nrog me me txoj kab uas hla, uas yog tsuas yog siv nyob rau hauv kev tsim kho tej hauj lwm.

Hlau pas nrig yog cov khoom siv hlau uas feem ntau muaj qhov me me hla ntu thiab tuaj yeem dov.

SAE 1010 hlau pas nrig yog cov khoom siv hlau me me. Nws yog ib feem ntawm American Society of Automotive Engineers (ASAE) cov qauv, uas yog siv los qhia cov tshuaj muaj pes tsawg leeg thiab cov khoom siv ntawm cov hlau me me.

SAE1008 hlau qws yog ib tug me me steel hlau pas nrig nrog siab malleability, machinability thiab zoo welding zog.

Sae1006 hlau pas nrig yog cov khoom siv qis carbon steel nrog cov yas zoo heev, weldability thiab zoo nto zoo.

Q195 thiab Q235 yog ob qho tib si qib ntawm carbon structural steel, thiab lawv yog ob qho tib si carbon structural steels, piv txwv li, lawv tsis muaj lub hom phiaj ntxiv alloying ntsiab.

Dub annealed hlau, tseem hu ua dub high-temperature hlau, yog cov khoom siv filamentary ua los ntawm cov hlau molybdenum, tungsten thiab lwm cov ntaub ntawv kub.

Galvanized hlau feem ntau yog siv los khi thiab kho hauv kev tsim kho, kev ua liaj ua teb, tsev neeg thiab lwm yam kev lag luam, thiab ua tau zoo hauv kev tiv thaiv corrosion thiab kav ntev.
