Cov Qauv Hlau (xws li, GB / T 700 Q215A)
Nyob rau hauv Suav qauv (GB / T 700), Q215A yog cov hlau txheem cov hlau txheem.
Q: "Tawm los," qhia tau lub zog zog.
215: Yam tsawg kawg nkaus tuaj lub zog muaj zog ntawm 215 MPA.
A: Qib zoo (A yog qib pib, nrog cov kev cuam tshuam qis dua yuav tsum muaj dua B, C, lossis D).
Siv rau kev tsim kho dav dav, cov kav dej piping, lossis qis - kev siv kev ntxhov siab.
1. Kev faib tshuaj ntawm cov roj carbon hlau
(1) Kev faib tawm los ntawm cov ntsiab lus carbon
Hom cov ntsiab lus carbon (%) cov yam ntxwv thiab kev siv
Cov roj carbon qis 0.05 ~ 0.25 zoo plasticity, yooj yim rau weld, siv rau cov phiaj colled, steel tuav, tsheb lub cev, thiab lwm yam.
Nruab Nrab Carbon Steel 0.25 ~ 0.60 siab zog, siv rau cov khoom siv kho tshuab (zog, thiab lwm yam)
Siab carbon hlau 0.60 ~ 2.10 siab tawv, siv rau cov cuab yeej, springs, ntsia, thiab lwm yam.
(2) Kev faib tawm los ntawm daim ntawv thov
Cov hlau qauv: siv rau cov tsev thiab cov choj (xws li Q235, A36).
Cuab Steel: siv rau cov cuab yeej thiab cov pwm (xws li T8, T10).
Tshwj xeeb hom phiaj hlau: xws li boiler steel, nkoj hlau, thiab lwm yam.
(3) kev faib tawm los ntawm txoj kev smelting
Bos steel: xws li cov pa roj carbon (Q Series).
EAF Steel: xws li high - Zoo Carbon Hlau (45 #) {3 #) {3 #)}
