Txheej txheem cej luam ntawm Galvanized Oval Hlau
Raws li lub siab tensile lub zog qauv, uas yog corrosion, cov xeb, ruaj khov thiab siv khoom siv, cov khoom lag luam, cov khib nyiab thiab cov neeg cog lus. Nws yog qhov tseem ceeb li nyuj laj kab xaim hluav taws xob ua liaj ua teb tshwj xeeb, kev ua liaj ua teb, cov vaj tswv teb, kev ua liaj ua teb, thiab cov huab cua, thiab lwm yam.
Galvanized Oval hlau tau muab faib ua kev faib ua si

Hom Carbon Hlau Hlau
Cov pa roj carbon hlau tsis muaj peev xwm paub tias yog hlau me, cov ntsiab lus carbon los ntawm 0.10% rau kev zam ntawm cov saw hlau, rivets, bolts, polts, shafts thiab Yog li ntawd.
(2) Nruab Nrab Carbon steel carbon hlau nrog cov ntsiab lus carbon nrog 0.25% rau 0.60%. Muaj ntau cov khoom lag luam xws li tua cov hlau, ib nrab tua hlau, hlau npau npau. Ntxiv rau cov pa roj carbon, nws yuav muaj ib qho me me ntawm manganese (0.70% rau 1.20%).
(3) Cov pa roj carbon ntau feem ntau xa mus ua cuab yeej hlau, cov ntsiab lus carbon, tuaj yeem ua tau zoo thiab tempered. Hammers, Crowbars, thiab lwm yam yog ua los ntawm cov hlau nrog cov ntsiab lus carbon ntawm 0.75%; tej cuab yeej xws li tho qhov, hlau cov kais dej, reamers, thiab lwm yam yog ua los ntawm cov ntsiab lus carbon nrog 0.90% mus rau 1.00%
