Ob leeg cov ntaub ntawv yog txias- dov nyob rau hauv chav tsev kub thiab annealed rau optimize ductility, tab sis lawv metallurgical designs yog haum rau kev daws teeb meem txawv manufacturing.
Chemical Composition & Mechanical Properties: Sab -los ntawm -Side Comparison
Qhov sib txawv tshaj plaws ntawm DC01 thiab DC05 yog nyob rau hauv lawv cov tshuaj tswj nruj nruj thiab cov khoom siv tshuab, uas ncaj qha txiav txim siab lawv cov formability. Hauv qab no yog tus kws tshaj lij, tus qauv- ua raws cov lus sib piv lawv cov ntsiab lus tseem ceeb, ua raws li EN 10130: 2006:
| Yam khoom | Parameter | DC01 Specification txwv | DC05 Specification txwv |
|---|---|---|---|
| Tshuaj muaj pes tsawg leeg | Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.12% | Tsawg dua lossis sib npaug li 0.008% |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 0.60% | Tsawg dua lossis sib npaug li 0.30% | |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.045% | Tsawg dua lossis sib npaug li 0.020% | |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.045% | Tsawg dua lossis sib npaug li 0.02% | |
| Txhuas Txhuas (Alt) | Ntau dua lossis sib npaug li 0.010% | Ntau dua lossis sib npaug li 0.015% | |
| Mechanical Properties | Yield zog (Rp0.2) | 140 ~ 280 MPa | 120 ~ 180 MPa |
| Tensile zog (Rm) | 270 ~ 410 MPa | Ntau dua lossis sib npaug li 270 MPa | |
| Elongation tom qab tawg (A80mm) | Ntau dua lossis sib npaug li 28% | Ntau dua lossis sib npaug li 38% (siab tshaj txog 46%) | |
| Formability Rating | Sib sib zog nqus-Kev muaj peev xwm kos duab | Basic (lub teeb stamping nkaus xwb) | Ultra-siab (qhov tob tob heev) |
Cov lus no qhia txog qhov sib txawv ntawm cov hlau metallurgical: DC05 muaj qhov ultra- cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.008% vs. DC01's Less dua lossis sib npaug li 0.12%), uas ua rau muaj zog ductility thiab txo cov yield zog. DC05 qhov siab tshaj plaws elongation ntawm 46% yog 64% siab dua DC01 qhov tsawg kawg nkaus 28%, ua rau nws tuaj yeem tiv taus qhov deformation uas yuav ua rau DC01 poob tam sim ntawd.
Qhov tseem ceeb ntawm kev ua tau zoo sib txawv
1. Formability & Deep-Kev muaj peev xwm kos duab
DC01 tsuas yog txwv rau qhov yooj yim, qis- deformation stamping kev ua haujlwm, thaum DC05 yog tsim los rau kev sib sib zog nqus nqus thiab sib sau ua ke.DC01 qhov nruab nrab elongation (Ntau dua lossis sib npaug li 28%) ua rau nws tsim nyog rau qhov ntiav ntiav, khoov, thiab yooj yim blanking, tab sis nws tsis tuaj yeem tuav hnyav ncab lossis cov duab sib txawv yam tsis muaj cracking lossis wrinkling. Hauv qhov sib piv, DC05's 46% qhov siab tshaj plaws elongation thiab lub zog tsis tshua muaj zog (120-180 MPa) tso cai rau nws los tsim rau hauv qhov sib sib zog nqus, nyuaj geometries nyob rau hauv ib qho kev lag luam stamping, ua rau nws zoo tagnrho rau qhov chaw uas yuav tsum tau ua ntau theem.
2. Surface Quality & Dimensional Accuracy
Ob lub DC01 thiab DC05 muab cov khaub thuas- dov du nto, tab sis DC05 yog tsim los nrog kev tswj xyuas nruj dua rau siab - thov kev thov.DC01 feem ntau yog muab rau hauv FB (Higher Qib) qhov zoo ntawm qhov tsis yog- pom cov khoom, thaum DC05 muaj nyob rau hauv peb qib hwm (FB, FC, FD), suav nrog FD (Super High Grade) rau qhov tsis zoo sab nrauv tsheb thiab cov khoom siv vaj huam sib luag. DC05 kuj muaj nruj dua thickness kam rau ua tswj, kom ntseeg tau raws li qhov ntev ntawm qhov raug rau precision manufacturing, whereas DC01 muaj looser kam rau ua rau dav dav - hom phiaj siv.
3. Weldability & Processability
DC01 muaj qhov zoo tshaj plaws weldability rau general daim ntawv thov, thaum DC05 muaj kev sib txuas zoo dua rau siab - ntim, kev sib dhos precision.Ob leeg yog tsawg- carbon steels sib xws nrog cov txheej txheem vuam txheej txheem (qhov chaw vuam, MIG, TIG), tab sis DC05's ultra- cov ntsiab lus qis carbon thiab impurity txo qhov kev pheej hmoo ntawm vuam tsis xws luag, ua rau nws zoo tagnrho rau cov tsheb thiab cov khoom siv sib dhos uas yuav tsum tau ua kom zoo ib yam, siab - lub zog welds. DC05 kuj tseem txhawb nqa ntau yam ntawm kev ua haujlwm theem nrab (slitting, leveling, galvanizing, painting) nrog cov khoom siv tsawg tsawg, thaum DC01 tsuas yog siv rau kev ua haujlwm yooj yim.
4. Tus nqi & khoom siv tau zoo
DC01 yog tus nqi -kev nkag tau zoo- cov khoom siv qib, thaum DC05 yog tus nqi hwm- cov khoom qib nrog tus nqi siab dua tab sis qis dua - cov nqi tsim khoom.DC01 yog qhov pheej yig dua li DC05, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev yooj yim, qis - cov ntsiab lus kev ntxhov siab. Txawm li cas los xij, DC05's superior formability txo cov seem seem, tshem tawm cov txheej txheem thib ob, thiab txuas ntxiv lub neej tuag, ua rau txo qis tag nrho cov nqi tsim khoom rau kev sib sib zog nqus sib sib zog nqus- cov khoom kos. Rau cov tuam txhab tsim cov khoom lag luam siab - ntim cov khoom sib xyaw, DC05 tus nqi khoom siv ntau dua yog offset los ntawm kev txo cov khib nyiab thiab txhim kho kev ua haujlwm.
