Raws li ib tus neeg muab kev ntseeg siab rau cov tuam txhab tsheb tuam txhab tsheb, peb tshwj xeeb hauv SPCC / SGACC / SGAHC txias- dov steel coil cov kev daws teeb meem kom haum rau siab - lub zog automotive Cheebtsam. Rau cov lag luam nrhiav cov khaub thuas dov steel lag luam wholesale, nkag siab txog cov qib no, lawv cov tshuaj pleev ib ce, thiab CRC steel nqe qauv Tuam Tshoj yog ib qho tseem ceeb rau optimizing cov nqi ntau lawm thiab zoo. Phau ntawv qhia no rhuav tshem cov khoom tseem ceeb, kev siv, thiab cov kev xav tseem ceeb rau kev tsim cov khoom siv tsheb.
SPCC, SGACC, thiab SGAHC yog kev lag luam -qib txias- dov steel (CRC) qib tsim los rau nruab nrab mus rau siab formability- zoo tagnrho rau stamping thiab dabtsi yog khoov tsheb brackets. SPCC yog tus qauv dav dav- hom phiaj qib, thaum SGACC muaj kev txhim kho corrosion, thiab SGAHC muab lub zog tensile ntau dua rau kev thauj khoom- cov ntawv thov kev siv cov kabmob. Raws li ib tug ua lag luam wholesale txias dov steel tsum, peb xa cov coils rau Nyab Laj lub Haiphong Chaw nres nkoj (CIF cov nqe lus) nrog zoo ib yam zoo thiab kev sib tw nqi raws li CRC steel nqe qauv Tuam Tshoj.
Txias-Rolled Steel Coils
Ntsiab Specifications & Chemical Composition
| Qib | SPCC txias dov steel tshuaj muaj pes tsawg leeg(max, %) | Tensile zog (MPa) | Elongation (%) |
|---|---|---|---|
| SPCC | C: 0.15, Mn: 0.60, P: 0.045, S: 0.050 | 270–410 | Ntau dua lossis sib npaug li 26 |
| SGACC | C: 0.12, Mn: 0.60, P: 0.040, S: 0.040 (ntxiv rau corrosion inhibitors) | 270–420 | Ntau dua lossis sib npaug li 25 |
| SGAHC | C: 0.12, Mn: 0.80, P: 0.040, S: 0.040 (siab-lub zog alloyed) | 320–450 | Ntau dua lossis sib npaug 22 |
Txhua qib ua raws li JIS G3141 thiab cov qauv tsheb thoob ntiaj teb, ua rau lawv sib haum nrog kev tsim khoom.
Khoom nta rau Automotive Brackets
- Formability: SPCC / SGACC / SGAHC muab cov ductility zoo heev, ua rau txoj kev sib tw ntawm cov bracket geometries tsis tawg.
- Lub zog & Durability: SGAHC lub zog tensile siab dua txhawb nqa hnyav - lub luag haujlwm tsheb thauj khoom - cov ntawv thov kev coj tus kheej.
- Corrosion Resistance: SGACC txoj kev kho saum npoo txuas ntxiv lub neej kev pabcuam ntawm cov hlua khi hauv qhov chaw ua haujlwm hnyav.
- Nqi Efficiency: Astxias dov steel lag luam wholesalecov khoom, cov qib no sib npaug kev ua tau zoo thiab pheej yig, ua raws li qhov ruaj khovCRC steel nqe trend China.
- Kev sib raug zoo: Tight dimensional tolerances kom precision nyob rau hauv bracket fabrication, txo cov khoom pov tseg.
Kev siv hauv Automotive Bracket Parts
Cov khaub thuas no - dov steel coils tau dav siv hauv:
- Chassis brackets thiab lub rooj txhawb nqa cov khoom siv rau cov tsheb
- Cav mount brackets thiab ncua kev kawm ntawv qhov system
- Qhov rooj hinge brackets thiab kev txhawb nqa sab hauv
- Exhaust system brackets xav tau kev tiv thaiv corrosion (SGACC)
CRC Steel Nqe Nqe Tuam Tshoj (2026 Hloov Kho)
Tam sim noCRC steel nqe trend Chinaqhia tau hais tias tus nqi ruaj khov rau tsheb- qib coils, nrog kev hloov pauv nruab nrab uas tau tsav los ntawm cov nqi raw khoom thiab nqi zog. Rautxias dov steel lag luam wholesalexaj (20 tons / hli, 240 tons / xyoo) xa tawm mus rau Nyab Laj Chaw nres nkoj Haiphong, cov nqi tseem muaj kev sib tw, nrog rau ntev - cov ntawv cog lus kaw rau hauv cov nqi kom txo qis kev hloov pauv.
Cov lus nug nquag nug (FAQ)
1.Dab tsi yog SPCC txias dov steel tshuaj muaj pes tsawg leeg?
SPCC txias dov hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.15%, manganese 0.60%, phosphorus 0.045%, thiab sulfur 0.050%, optimized for general formability.
2.Yuav ua li cas txias dov steel lag luam wholesale nqe ua hauj lwm rau automotive qib?
Tus nqi lag luam wholesale yog ntim-raws li: kev txiav txim loj (Ntau dua lossis sib npaug li 20 tons / hli) tsim nyog rau cov nqi luv nqi, ua raws liCRC steel nqe trend Chinathiab CIF Haiphong cov ntsiab lus.
3.Qhov qib twg yog qhov zoo tshaj rau siab - lub zog tsheb kauj vab?
SGAHC yog qhov zoo tagnrho rau kev thauj khoom-cov kabmob, muab lub zog tensile ntau dua (320–450 MPa) piv rau SPCC thiab SGACC.
4.Dab tsi tsav CRC steel nqe qauv Tuam Tshoj xyoo 2026?
Cov ntsiab lus tseem ceeb suav nrog cov nqi hlau hlau, tus nqi hluav taws xob, thiab kev xav tau tsheb thoob ntiaj teb, nrog cov nqi xa tawm ruaj khov rau cov lag luam Esxias sab hnub tuaj xws li Nyab Laj.
5.Cov qib no puas tuaj yeem siv rau kev xeb- cov khoom siv hauv tsheb?
Yog lawm, SGACC nta txhim khu kev tiv thaiv corrosion, ua rau nws tsim nyog rau kev siv cov pa hluav taws xob thiab cov khoom siv hauv qab.
