Q235 thiab Q355 yog ob txoj kev sib txawv ntawm cov qauv siv hlau sib txawv hauv Suav teb, txhua tus nrog cov khoom sib txawv thiab cov ntawv thov:
Q235 STEEL
- Composition: Q235 steel yog cov hlau qauv hlau, uas cuam tshuam los ntawm nws lub zog siab, muaj zog zoo, thiab tawv.
- Tshuaj lom neeg muaj tshuaj: feem ntau muaj tsawg dua 0.3% carbon, 0.3% rau 0.7% manganese, 0.15% rau 0.35% silicon, thiab kab ntawm lwm yam ntsiab lus.
- Cov Khoom: Nws muaj cov tshuaj weldability thiab machinability zoo heev, kev siv vaj tse, thiab cov ntawv thov uas yuav tsum muaj tab sis tsis tas yuav muaj siab heev.
Q355 Hlau
- Composition: Q355 steel yog lub siab- muaj zog tsawg {} aliece} all lub zog thiab lub zog siab thiab cov neeg kho kom zoo nkauj.
- Tshuaj lom neeg tshuaj lom neeg: muaj ntau ntau cov roj carbon, manganese, silicon, thiab tej zaum lwm yam alloying, chromium, lossis tooj liab piv rau Q235.
- Cov khoom: Q355 steel muaj lub zog zoo dua thiab kev nruj sib piv rau cov neeg xav tau ntau xws li txuas ntxiv txuas ntxiv xws li cov choj, thiab cov cuab yeej siv hnyav.
Qhov sib txawv
- Lub zog thiab tawv: Q355 tau ua kom muaj zog dua siab dua thiab tawv dua Q235 vim nws cov ntsiab lus dav dav thiab cov ntsiab lus muaj roj carbon ntau dua.
- Cov Ntawv Thov:Q235 yog siv qhov uas muaj lub zog nruab nrab thiab cov weldability zoo yog qhov uas xav tau lub zog siab dua, ua kom muaj kev tawm tsam thiab rhuav.
- Nqi:Q355 feem ntau kim dua Q235 vim nws cov khoom siv txhim kho thiab cov ntsiab lus alloy.
Cov kev sib txawv no ua Q355 haum rau cov ntawv thov kev xav ntau dua uas muaj zog dua thiab ua tau zoo. Nyob rau tib lub sijhawm, Q235 yog siv nyob rau hauv cov ntawv thov tseem ceeb tsawg dua uas raug nqi- cov qauv tsim nyog thiab cov qauv dav dav txaus.

Cov FAQ
Q: Dab tsi yog Q355 steel?
A: Q355 steel yog lub siab-}} Lub zog steel uas yog feem ntau siv hauv kev lag luam ntau yam thiab kev siv. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias tsis muaj ib qho tshwj xeeb "ntawm Q355 steel raws li nws tsis tau muab tso cai siv cov qauv ib txwm muaj xws li Q235 lossis Q345.
Q: Dab tsi yog qhov txawv ntawm Q235 thiab Q355 steel?
A: Cov ntawv thov: Q235 yog siv qhov uas muaj lub zog nruab nrab thiab cov weldability zoo yog qhov xav tau lub zog siab dua, kav ntev, thiab kev tawm tsam thiab kua muag. Tus nqi: Q355 feem ntau kim dua Q235 vim nws cov khoom siv txhim kho thiab cov ntsiab lus alloy.
Q: Suav hlau qib Q355?
A: Q355 yog ib qib tshiab ntawm Suav hlau tshiab uas tau tsim los hloov Q345. Nws cov ntaub ntawv ceev yog 7.85 g / cm3 thiab muaj qib peb tau zoo, suav nrog Q355B, Q355C, thiab Q355d. Nws muaj cov kws kho tshuab thiab kub thiab txias cov txheej txheem.
