Dab tsi yog qib ntawm txias yob steel?
Txias- cov qib steel dov raug cais los ntawm lawv cov ntsiab lus carbon thiab daim ntawv thov, suav nrog qib kev lag luam xws li CS (Kev Lag Luam Zoo) thiab DQ (Drawing Quality), uas yog siv rau kev tsim qauv thiab cov ntawv thov uas xav tau kev kos duab sib sib zog nqus, feem. Cov qauv qib zoo li CR220 thiab HSLA yog siv rau kev thauj khoom- cov ntawv thov kev coj tus kheej, thaum lwm tus zoo li 1018 thiab 1020 tau muab faib ua cov qib carbon nruab nrab.
1.DC07 Sib npaug Steel Qib nyob rau hauv International Standards
Table 1. International Equivalent Grade Overview
| Qhov system | Qib | Zoo sib xws | Ntsiab nta |
|---|---|---|---|
| JIS (Nyiv) | SPCE-SD / SPCE | Siab | Haum rau kev sib sib zog nqus & ntxiv - kos duab sib sib zog nqus |
| ASTM (USA) | A1008 UAS | Nruab nrab | Ntxiv -sib sib zog nqus hlau |
| ISO | CR4 / CR5 | Nruab nrab | High ductility thiab tob drawability |
| Tuam Tshoj GB | DC06 (qib ze tshaj hauv tsev) | Nruab nrab -High | Tsawg yield zog & zoo heev formability |
| Korea KS | SPCE | Siab | Dav siv nyob rau hauv automotive stamping |
Nrhiav qhov tseem ceeb:
ThaumDC07 tsis muaj qhov zoo sib xws 1: 1, JIS SPCEthiabASTM EDDSyog cov kev xaiv ze tshaj plaws rau cov tuam txhab nrhiav kev ua haujlwm zoo sib xws.
2.DC07 vs Equivalent Qib - Kev sib piv
Table 2. Mechanical Property Comparison
| Khoom | dc07 ua | SPCE | EDDS | dc06 ua |
|---|---|---|---|---|
| Yield zog | Tsawg dua lossis sib npaug li 140 MPa | Tsawg dua lossis sib npaug li 160 MPa | Tsawg dua lossis sib npaug li 170 MPa | Tsawg dua lossis sib npaug li 160 MPa |
| Tensile zog | 240-310 MPa | 260-330 MPa | 260-340 MPa | 270-330 MPa |
| Elongation | Ntau dua lossis sib npaug li 38% | Ntau dua lossis sib npaug li 36% | Ntau dua lossis sib npaug li 36% | Ntau dua lossis sib npaug li 37% |
| Deep Drawing Muaj peev xwm | ★★★★★ | ★★★★☆ | ★★★☆☆ | ★★★★☆ |
| Thickness Ntau | 0.3-3.0 hli | Zoo sib xws | Zoo sib xws | Zoo sib xws |
Qhov kev sib piv no pab cov neeg yuav khoom nkag siab tias lwm qib twg yuav siv tau thaum DC07 tsis muaj lossis thaum txhim kho tus nqi yam tsis muaj kev cuam tshuam kev ua haujlwm.
Vim li cas thiaj xaiv GNEE STEEL rau DC07 Cov Khoom Siv Zoo?
Raws li tus thawj coj txias-khoov steel xa khoom:
✔ 20+ xyoo export kev
