Round steel yog hais txog ib tug ntev steel bar nrog ib ncig cross-section. Nws specifications qhia nyob rau hauv txoj kab uas hla nyob rau hauv millimeters (mm). Piv txwv li, "50mm" txhais tau hais tias ib puag ncig steel nrog txoj kab uas hla ntawm 50 hli.
Round steel muab faib ua peb hom: kub dov, forged thiab txias kos. Cov specifications ntawm kub dov round steel yog 5.5-250 hli. Ntawm lawv: me me puag ncig steel ntawm 5.5-25 hli feem ntau yog muab rau hauv cov kab ncaj nraim thiab pob khoom, thiab feem ntau yog siv los ua steel tuav, bolts thiab ntau yam khoom siv; round steel loj dua 25 hli yog siv los tsim cov khoom siv kho tshuab thiab seamless steel yeeb nkab blanks. tos.
Kev faib tawm los ntawm cov tshuaj muaj pes tsawg leeg: Carbon steel tuaj yeem muab faib ua cov pa roj carbon tsawg, cov pa roj carbon nruab nrab thiab cov pa roj carbon siab siab raws li nws cov tshuaj muaj pes tsawg leeg (piv txwv li, cov ntsiab lus carbon). (1) Tsawg carbon steel kuj hu ua me me hlau. Cov ntsiab lus carbon yog los ntawm 0.10% mus rau 0.30%. Tsawg carbon steel yog ib qho yooj yim los txais ntau yam kev ua xws li forging, vuam thiab txiav. Nws yog feem ntau siv los tsim cov chains, rivets, bolts, shafts, thiab lwm yam.
