Q235NH steel phaj

Nov 21, 2025 Tso lus

Hauv ntiaj teb ntawm kev tsim vaj tsev thiab kev tsim kho, xaiv cov khoom tsim nyog yog qhov tseem ceeb rau kev ua kom lub neej ntev, kev nyab xeeb, thiab tus nqi- ua haujlwm tau zoo. Ntawm cov huab cua array-cov hlau tsis muaj zog, Q235NH steel phaj sawv tawm raws li kev xaiv txhim khu kev qha rau cov qauv welded raug rau huab cua hnyav.

Tsim los rau Suav teb tus qauv GB / T 4172-2000 rau atmospheric corrosion-resisting steel rau welded lug, Q235NH muaj tshwj xeeb durability yam tsis tas yuav tsum tau rau nws kim heev tiv thaiv txheej.

GB / T 4172 tus qauv tshwj xeeb yog tsim los rau cov hlau siv hauv cov khoom siv welded uas yuav tsum tau ua haujlwm rau atmospheric corrosion. Tsis zoo li cov qauv hlau dav dav, cov ntaub ntawv no yog tsim los tsim kom muaj kev ruaj khov, tiv thaiv xeb txheej (patina) thaum raug rau cov ntsiab lus, uas ua raws li kev thaiv kev tiv thaiv ntxiv oxidation. Qhov no ua rau lawv zoo tagnrho rau ib puag ncig nrog cov av noo siab, raug ntsev, los yog muaj kuab paug.

Q235NH, ib qho ntawm cov qhab nia tseem ceeb raws li tus qauv no, muab nws lub npe los ntawm nws qhov tsawg kawg nkaus yield zog ntawm 235 MPa ("Q235") thiab "NH" npe qhia nws " atmospheric corrosion resistance" zog. Nws yog ib qho qis- alloy, siab - lub zog steel uas sib npaug ntawm cov nqi pheej yig nrog kev ua tau zoo, ua rau nws mus rau - rau kev xaiv rau pob nyiaj siv - cov haujlwm tseem ceeb yam tsis muaj kev cuam tshuam rau qhov zoo.
