Dc04

Dc04
DC04 yog txias -}} rolled steel ntawv qib teev teev nyob rau hauv German Din tus qauv (tam sim no tus neeg European en txheem). Nws yog txias - dov qis - cov ntawv hlau ua hlau. Nws cov yam ntxwv tseem ceeb thiab cov ntaub ntawv muaj raws li hauv qab no:
Kev Ua Tau Zoo: Qhov no tob - Teeb cov khoom txias thiab stamping cov khoom lag luam, ua kom haum rau cov ntawv siv stamping uas yuav tsum muaj kev sib txawv. Nws cov formability surpasses uas ntawm General - lub hom phiaj dc01 thiab tus qauv DC01 thiab cov rooj sib tham hauv nruab nrab- qhov tob stamping yuav tsum tau.
Tshuaj lom neeg tshuaj lom neeg (cov carbon) feem ntau tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug lossis ntau dua lossis 0.015% (acid {5} {soluble aluminium). Cov muaj pes tsawg leeg yog tsim los kom ntseeg tau tias ductility zoo heev thiab weldability. Feem ntau cov khoom siv cov khoom siv: tawm lub zog feem ntau ntawm 120-250 mpa, thiab elongation tom qab pob txha (A80mm) ntau dua lossis sib npaug ntawm 38%. Nws cov txiaj ntsig tsawg kom lub zog thiab elongation siab pab txhawb cov khoom siv yas ua haujlwm thaum lub thwj.
Cov ntawv thov: feem ntau siv hauv kev ua cov khoom siv hauv lub cev, xws li cov khoom siv hauv lub cev thiab cov khoom siv hluav taws xob hauv kev lag luam hauv tsev, thiab lwm yam khoom lag luam hlau uas yuav tsum tau ua siab ntev.
Kev Sau Ntawv: nws kwv yees li sib raug zoo sib xws rau lwm cov qauv, xws li Spce (ze rau tus qauv Japer) thiab 08al (sib sib zog nqus kos duab. Txawm li cas los xij, kev ua tsis tau tshwj xeeb yuav sib txawv me ntsis nyob ntawm cov txheej txheem ntau lawm thiab lwm yam.
