DC05 yog cov ntawv txias-carbon hlau tau teev nyob rau hauv European txheem (thiab siv 10130), feem ntau siv rau cov ntawv thov stamping thiab sib sau ua lag luam (piv txwv li siv tsheb). Nws cov tshuaj lom neeg muaj pes tsawg leeg yog feem ntau hlau (FE), nrog rau lwm cov ntsiab lus kom ntseeg tau zoo heev thiab muaj peev xwm. Cov hauv qab no yog ib txwm muaj tshuaj lom neeg muaj pes tsawg leeg thiab ua haujlwm ntawm cov hlau stainless:
1. Cov tshuaj lom neeg muaj pes tsawg leeg (feem pua
Qeb ntsiab lus ntau (%) muaj nuj nqi
C (carbon) tsawg dua los yog sib npaug rau 0.02 - 0.06 tsis muaj cov pa hluav taws kub hloov kho thiab tiv thaiv kev sib tsoo stamping
Mn (manganese) tsawg dua lossis sib npaug rau 0.25 - 0.40} Lub zog ferrite thiab txhim kho cov haujlwm ua haujlwm
P (phosphorus) tsawg dua los yog sib npaug rau 0.025 - 0.035}} ntau dhau
S (sulfur) tsawg dua los yog sib npaug rau 0.025 - 0.035}}} Cov nyiaj kwv yees, cuam tshuam rau kev ua haujlwm
Al (Aluminium) ntau dua lossis sib npaug rau 0.015 - 0.060 deoxidizer, rov qab tuav loj
Si (silicon) tsawg dua lossis sib npaug rau 0.03 - 0.05 residual keeb; Ntau dhau ntawm kev txo cov vixentity
NCO TSEG: Cov ntsiab lus tshwj xeeb yuav txawv me ntsis nyob ntawm cov qauv khoom (xws li EN 10130, DIN 1623).
2. Cov Khoom Siv Khoom Siv
Tsawg lub zog, siab plhaw: haum rau cov txheej txheem ua tiav xws li kev sib sib zog nqus thiab dabtsi yog khoov.
High nto rolled thiab me me-dov thiab annealed rau ib tug du nto (piv txwv, DC04, DC05, thiab DC06 muaj nce zuj zus).
3. Cov Ntawv Thov Tib Neeg
Automotive panels (qhov rooj, roj tso tsheb hlau luam)
Khoom siv hauv tsev (tshuab ntxhua khaub ncaws, tub yees ntoo
General stamping ntu (ntim, nkhaus)
4. Piv ntawm cov qhab nia zoo sib xws
Qib (En) C (%) Cov Txwv Hla Sab SCENT (Mpa) Elongation (%)
DC {01 0.10 270 - 410 Ntau dua lossis sib npaug 28
DC 04 0.08 260 - 380 Ntau dua lossis sib npaug rau 34
DC 05 0.06 250 - 360 Ntau dua lossis sib npaug 38
DC 06 0.02 240 - 350 Ntau dua lossis sib npaug rau 42
Lub ntsiab
DC05 tsis yog tshuaj lom neeg, tab sis theej cov pa roj carbon, txias-cov hlau ntim hlau. Nws cov ntsiab lus tseem ceeb yog FE, thiab nws cov ntawv txheej txheem yog optimized los ntawm nruj me ntsis tswj cov C thiab MN cov ntsiab lus. Rau cov ntawv sau meej cov ntaub ntawv, nws raug pom zoo los sab laj cov qauv txheem tshwj xeeb lossis cov khoom lag luam ntawv xeem.
