DC01 khoom yog dab tsi?
DC01: Feem ntau siv rau hauv cov ntawv thov uas cov qauv tsim tsis xav tau heev. Piv txwv li, nws yog siv rau hauv kev tsim cov khoom siv hauv lub cev uas muaj cov duab yooj yim, cov tso tsheb hlau luam, thiab qee qhov dav dav - cov khoom siv hlau.
DC03 steel qib yog dab tsi?
DC03 yog txias txias - dov qis - carbon steel qib uas yog European tus qauv EN 10130. Ntawm no yog cov lus qhia ntxaws:
1. Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm DC03 yog nruj me ntsis tswj kom ua tiav cov yam ntxwv tshwj xeeb.
Carbon (C): Nws muaj cov ntsiab lus carbon tsawg, feem ntau Tsawg dua lossis sib npaug li 0.08%. Cov ntsiab lus carbon tsawg yog qhov tseem ceeb rau kev txhim kho formability.
Manganese (Mn): Cov ntsiab lus manganese feem ntau tsawg dua lossis sib npaug li 0.40%. Manganese tuaj yeem txhim kho lub zog thiab hardness ntawm hlau mus rau qee yam.
Dab tsi yog qhov txawv ntawm DC01 thiab DC03 steel?
DC01 - Qib no tuaj yeem siv rau kev ua haujlwm yooj yim, xws li khoov, embossing, hlaws thiab kos duab. DC03 - Qib no tsim nyog rau kev tsim cov kev cai xws li kos duab sib sib zog nqus thiab nyuaj profileing. DC04 - Qib no yog tsim nyog rau kev tsim kom muaj siab.
DC01 B khoom yog dab tsi?
DC01 steel, yog ib qho tsis yog- alloy zoo steel nrog qis carbon. Ua raws li cov ntawv tiaj tus los ntawm txias dov, nws muaj qhov du thiab zoo formability. Hom muaj xws li DC01-A, DC01-B, thiab electro-galvanized DC01+ZE (1.0330+ZE) raws li EN 10152. Cov qauv muaj feem xyuam yog EN 10130 thiab EN 10131.
DC 04 khoom yog dab tsi?
Qib DC04 yog qhov sib sib zog nqus- kos duab hlau ntawm DC qib tsev neeg. Qib muaj qhov sib sib zog nqus zoo heev - kos duab hauv qab txhua hom deformation. DC04 yog qhov tsim nyog rau kev tsim cov kev xav tau siab.
