Dab tsi yog qhov tseem ceeb ntawm kev ua tau zoo ntawm Q235 steel kauj?
A: Zoo tag nrho kev ua tau zoo, tus nqi qis, weldability zoo heev, zoo plasticity thiab toughness, tsis muaj alloying ntsiab, yooj yim muaj raw cov ntaub ntawv, yooj yim ua technology, thiab tus nqi siab -effectiveness.
Dab tsi yog qhov ua tau zoo tshaj plaws ntawm Q235 steel kauj?
A: Lub zog tsis tshua muaj zog, tsis muaj kev tiv thaiv corrosion, lub zog ceev ceev poob ntawm qhov kub thiab txias, thiab tsis tshua muaj siab -kub toughness (A / B qib). Nws tsis tuaj yeem siv rau siab - zog, corrosion- tiv taus, lossis kev siv kub / qis.
Yuav ua li cas weldability ntawm Q235 steel kauj? Cov txheej txheem vuam dab tsi tuaj yeem siv tau?
A: Zoo heev weldability. Vim nws cov ntsiab lus tsis tshua muaj carbon, nws tsis tshua muaj siab tawv thaum vuam thiab tsis yooj yim rau vuam tawg. Txhua txoj kev vuam siv tau siv tau, suav nrog phau ntawv arc vuam, CO2 roj tiv thaiv vuam, submerged arc vuam, thiab roj vuam.
Q235 steel kauj puas tuaj yeem txias- ua haujlwm xws li stamping thiab dabtsi yog khoov? Cov kev cai tsim dab tsi tsim nyog?
A: Yog lawm, nws muaj cov yas zoo thiab tsim nyog rau kev yooj yim rau nruab nrab qhov txias txias (xws li khoov, ntiav stamping, thiab hemming), tab sis tsis yog rau kev sib sib zog nqus nqus (SPCC, DC01, thiab lwm yam txias- dov qis- cov pa roj carbon steel yog nyiam rau kev sib sib zog nqus nqus).
Q235 steel coils puas tuaj yeem ua kom sov- kho kom muaj zog? Vim li cas?
A: Tsis yog, vim tias nws tsis tshua muaj - carbon steel, kev kho cua sov (xws li quenching thiab tempering) tsis tuaj yeem hloov nws cov qauv metallographic lossis nce nws lub zog. Tsuas yog kev ntxhov siab -relieving annealing (tshem tawm kev ntxhov siab sab hauv tom qab ua haujlwm txias) tuaj yeem ua tau.
