Txias-rolled steel
Txias-rolled steel yog tsim los ntawm kev txo cov kub-rolled steel nyob rau hauv chav tsev kub, ua rau ib tug ntau dua - cov khoom muaj zog nrog superior nto zoo thiab qhov ntev precision. Nyob rau hauv qeb no,dc01 uathiabdc03 uayog ob qib thov dav uas ua haujlwm tsim thiab sib sib zog nqus-kev lag luam kos duab.
Ua ntej muab piv rau lawv, nws yog ib qho tseem ceeb kom nkag siab txog lub luag haujlwm ntawmdc01 ua, uas ua raws li lub hauv paus- qib steel zoo hauv DC series.
DC01 Steel yog dab tsi?
DC01 yog qib qis- carbon txias- dov steel qib tsim los rau khoov, shaping, thiab nruab nrab stamping. Nws nta:
- Zoo heev nto rau txheej thiab painting
- Stable mechanical zog
- Muaj peev xwm tsim tau zoo
- High precision nyob rau hauv thickness thiab dav
Nws versatility ua rau nws nrov nyob rau hauv automotive qhov chaw, industrial khoom vaj tse, thiab cov neeg siv khoom tsim khoom.
Chemical Composition thiab Alloying Strategy
EN tsev neeg DC0x txhob txwm tsis tshua muaj cov ntsiab lus ntawm cov alloy kom ua kom lub cev muaj zog thiab tswj qhov zoo. Kev sib xyaw ua ke tseem ceeb yog txo qis carbon, silicon, phosphorus thiab sulfur (impurities) es tsis yog ntxiv dag zog rau cov ntsiab lus alloying.
Cov lus: Cov ntsiab lus tseem ceeb hauv kev sib xyaw ua ke (qhia; sab laj tus qauv qauv lossis daim ntawv pov thawj tus neeg muag khoom kom muaj kev txwv meej)
| Element | DC01 (qhov tseem ceeb) | DC03 (qhov tseem ceeb) |
|---|---|---|
| C (carbon) | Tsawg; tswj kom ua kom txias dov thiab nruab nrab formability (DC01 siab dua li DC03) | Tsawg dua DC01 txhawm rau txhim kho kev kos duab sib sib zog nqus thiab txo qis kev ua haujlwm hnyav |
| Mn (zeeg) | Ntxiv me me rau kev tswj lub zog thiab dov (tswj qib) | Zoo ib yam li DC01 (siv rau lub zog / ci zog tswj) |
| Si (silicon) | Tsawg (deoxidation theem; nyhav kom txwv rau kev tswj saum npoo thiab sib sau) | Khaws cia sib npaug qis los yog qis dua los txhim kho drawability |
| P (phosphorus) | Khaws qis (impurity) | Khaws qis (zoo ib yam li DC01) |
| S (sulfur) | Khaws qis (impurity) | Khaws qis (zoo ib yam li DC01) |
| Cr, Ni, Mo, V, Nb, Ti, B | Tsis txhob txwm muab ntxiv rau qhov tseem ceeb; nthuav tawm ntawm residual/traces yog tias muaj | Tsis txhob txwm ntxiv (tsuas yog seem) |
| N (nitrogen) | Tswj kom tsis txhob embrittlement; feem ntau qis | Tswj tau; tsis tshua muaj kev txhawb nqa formability |
Mechanical Properties
Cov lus: Kev coj tus cwj pwm sib piv (zoo li - qhov tseem ceeb nyob ntawm qhov kub, tuab, thiab tus neeg muag khoom)
| Khoom | dc01 ua | dc03 ua | Saib |
|---|---|---|---|
| Tensile zog (ntau daim ntawv ntau) | Nruab nrab | Nruab nrab mus rau qis dua | DC03 feem ntau muab softer kom nyiam drawability |
| Yield zog | Siab dua DC03 (me ntsis) | Tsawg dua DC01 | Tsawg tawm los txo qhov yuav tsum tau muaj zog punch thiab txo qhov kev pheej hmoo springback |
| Elongation (txhim kho) | Zoo | Zoo tshaj DC01 | DC03 optimized rau ntau dua niaj hnub elongation rau sib sib zog nqus nqus |
| Impact toughness | Tsim nyog ntawm chav tsev kub | Zoo sib xws los yog me ntsis zoo dua | Tsis yog thawj qhov sib txawv; ob leeg yog ductile ntawm ambient temps |
| Hardness | Me ntsis siab dua (nyob ntawm qhov ua tiav) | Tsawg me ntsis | Hardness qhia txog kev ua haujlwm txias / anneal mob; DC03 softer nyob rau hauv ib txwm mob |
Summary and Recommendation
Table: Kev sib piv ceev
| Yam ntxwv | dc01 ua | dc03 ua |
|---|---|---|
| Weldability | Zoo | Zoo me ntsis (marginally) |
| Lub zog-Toughness balance | Lub zog nruab nrab nrog zoo ductility | Tsawg tawm los thiab siab dua uniform elongation - zoo formability |
| Nqi | Feem ntau qis dua | Feem ntau me ntsis siab dua |
| Zoo tshaj rau | General stamping thiab panels | Sib sib zog nqus daim duab thiab complex forming |
