SAE4140, SAE4130 thiab SAE4340 puag ncig cov khoom siv yog cov khoom siv hlau alloy, koom nrog Asmeskas tus qauv ASTM A29 qib, uas sib haum rau 40CrNiMo, 40CrNiMoA thiab 40CrNi2Mo hauv Suav teb tus qauv GB / T 3077-20.

Cov pa roj carbon steel puag ncig bar muaj ntau yam kev siv hauv thaj chaw xws li kev tsim kho, kev tsim khoom siv tshuab thiab kev lag luam tsheb vim nws lub zog siab, puas thiab corrosion kuj. Nws yog ua tiav nyob rau hauv ntau txoj kev, nrog rau kev txiav, drilling thiab kev kho cua sov.

Anti slip hlau grating yog dav siv nyob rau hauv ntau yam ntub dej, greasy los yog icy ib puag ncig, xws li zaub mov ua zaub mov, tshuaj tuam txhab uas muag, chaw nres nkoj terminals thiab lwm yam muaj kev pheej hmoo.

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.

Steel bar yog cov khoom siv hlau cylindrical dav siv hauv ntau qhov chaw. Raws li cov ntaub ntawv sib txawv thiab lub hom phiaj, cov kab puag ncig tuaj yeem muab faib ua ntau hom, txhua tus nrog nws cov kev thov tshwj xeeb thiab cov yam ntxwv.

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.

Kub dov round steel bar yog ib lo lus metallurgical rau ib hom round steel bar, uas yog ib hom kev tsim steel.
