Qhov txawv ntawm Q235 kub dov steel phaj thiab txias dov steel phaj

Kub dov phaj muaj tsawg hardness, yooj yim ua, thiab zoo ductility. Txias dov phaj muaj siab hardness, kuj nyuaj ua, tab sis tsis yooj yim rau deform, thiab muaj zog dua. Kub dov phaj muaj lub zog qis, me ntsis tsis zoo ntawm qhov zoo (tsis tshua muaj oxidation brightness), tab sis zoo plasticity, feem ntau nruab nrab tuab phaj. Txias dov phaj: siab zog, siab hardness, siab nto brightness, feem ntau nyias phaj, yuav siv tau raws li stamping phaj. Kub dov steel phaj muaj cov khoom siv kho tshuab tsis zoo rau kev ua haujlwm txias, thiab tsis zoo rau kev ua haujlwm, tab sis muaj qhov zoo toughness thiab ductility. Txias dov steel phaj muaj qee qhov kev ua haujlwm hardening, tsis tshua muaj zog, tab sis tuaj yeem ua tiav cov txiaj ntsig zoo zog, siv rau lub caij nplooj ntoos hlav txias thiab lwm yam. Nyob rau tib lub sijhawm, vim tias qhov taw tes tawm los yog ze rau lub zog tensile, tsis muaj kev twv ua ntej ntawm kev txaus ntshai nyob rau hauv cov txheej txheem ntawm kev siv, thiab kev huam yuaj yuav tshwm sim thaum lub load tshaj qhov tso cai load. Kub dov yog dov steel phaj rau hauv ib lub phaj nyias nyias ntawm qhov kub siab dua; txias dov yog dov steel phaj raws li qhov kub thiab txias. Feem ntau, kub dov yog ua ntej, tom qab txias dov. Thaum lub phaj steel yog tuab, tsuas yog kub dov tuaj yeem siv tau. Tom qab dov mus rau hauv nyias daim hlau, txias dov yog nqa tawm. Kub dov steel phaj muab faib ua cov phaj tuab (thickness ntau dua 4mm) thiab nyias daim hlau (thickness ntawm 0.35 ~ 4mm); txias dov steel phaj tsuas yog nyias daim hlau (thickness ntawm 0.2 ~ 4mm).
