Q235 carbon steel phaj ua raws li ASTM A36 muab cov khoom lag luam zoo heev los ntawm kev tswj cov tshuaj kom raug (carbon ≤0.22% nruab nrab 0.18%, manganese 0.80-1.20%, phosphorus ≤0.04% ntsuas ≤0.035%, sulfur zog ≤0.05% tensile zog ≤0.05%) 400-550 MPa (kuaj los ntawm lwm tus nruab nrab 480 MPa), yield zog ≥250 MPa (qhov ntsuas qis tshaj 265 MPa, zoo tshaj tus nqi), elongation ≥20% (qauv ntsuas 23%), carbon equivalent Ceq ≤0.37% kom ua tau kev weldability zoo.
Hauv qhov chaw thiab kub li qub, nws lub neej siv tau mus rau ntau tshaj 10 xyoo (hauv chaw chaw lag luam dej, kuj tuaj yeem tshaj 5 xyoo, uas ntau dua li qee cov carbon steel tsis zoo li 2 xyoos). 3mm tuab Q235 carbon steel phaj tuaj yeem xaiv tau 4mm li qub low-carbon steel, thaum ua kom muaj zog, tuaj yeem khaws cov neeg siv nyiaj txog $800 ib ton hauv cov nqi khoom.
Peb muab sandblasting thiab painting nto kho. Qhov roughness Ra tom qab sandblasting yog ntawm 40-80μm, ua tau raws li SSPC-SP 10 nruab. Cov xim dub sib sib zog nqus, qhov qhuav film thickness tau 80-120μm, thiab adhesion qib tau 5B hauv ASTM D3359. Peb tuaj yeem ua precision plasma txiav, qhov kam rau ua yog tswj hauv ± 0.1mm, thiab shear straightness yog ≤1mm/3m, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv lub loj ntawm phaj.
Cov txheej txheem smelting sivrc furnace + LF furnace refining (nitrogen ntsiab lus ≤80ppm), nruab nrog advanced X-ray fluorescence spectrometer rau kev zoo nkauj muaj pes tsawg leeg, nrog rau cov ntsiab lus ntawm 0.001%.
Peev xwm txhua xyoo nco 30,000 tons, uas yog nyob rau theem ua nyob rau ntawm cov factories zoo ib yam hauv ntiaj teb teb. Ntawm lawv, tsis muaj ntau tshaj 10 lub factories uas tuaj yeem tsim tau ≥20,000 tons khoom; 500 tons nyob tas li, cover cov specifications li 3mm/6mm/10mm (ntawm cov khw tuaj yeem nrhiav los ntawm online system).
tag nrho pawg kho mob tensile (raws li ASTM E8
Kev txiav txim ib zaug 50 tons thiab siab dua tuaj tau txais luv nqi txog 8%, kev pab ua dawb thiab txo nqi rau me me rau ib feem. Peb lees tias yog tias cov khoom zoo ntawm Q235 carbon steel phaj tsis tau raws li ASTM A36, los yog muaj kev poob qis tsis yog neeg nyob hauv chaw siv li qub, peb yuav them tag nrho.

Cov Lus Nug Feem ntau
Q: Koj puas tau xaj xaj rau kuv?
A: Yog, peb tau txais kev xaj kuv. Txawm li cas los xij, peb yuav muab cov khoom zoo thiab kev pab zoo ib yam li kev xaj loj.
Q: Koj txhawb cov kev them nyiaj twg?
A: Peb txhawb T/T, L/C, thiab Western Union. Rau cov neeg siv li niaj hnub sib tham, peb tuaj yeem sib tham txog cov lus cog tseg yooj yim dua.
Q: Koj puas tuaj yeem muab daim ntawv qhia khoom kom haum?
A: Yog, peb yuav xa daim ntawv qhia digital nrog specifications, nqi, thiab duab los ntawm email. Cia peb paub koj cov kev xav tau kev vam meej.
Q: Koj ua li cas kom ntseeg tau tias cov specifications ntawm khoom yog raug?
A: Txhua yam khoom raug ntsuas los ntawm peb pab neeg QC siv cov ntsuas ntsuas raug, thiab peb muab MTC (Material Test Certificate) los lees paub cov specifications.
