DX51D khoom sib npaug yog dab tsi?
SGCC
DX51D yog tus qauv European, galvanized nrog 51 steel coil raw khoom, sib npaug rau SGCC. DX51D yog hais txog kev khoov thiab tsim qib galvanized steel kauj daim ntawv, cov hlau qib serial tooj yog 51, nrog cov pa roj carbon tsawg yog cov khoom siv hauv paus.
Cov ntsiab lus carbon:
DX51D: Feem ntau muaj cov pa roj carbon ntau dua piv rau DX52D. Cov ntsiab lus carbon ntau dua tuaj yeem ua kom lub zog ntawm cov hlau mus rau qee qhov.
DX52D: Feem ntau muaj cov ntsiab lus qis dua, uas ua rau muaj kev ua tau zoo dua.
Lwm yam Alloying Elements: Cov nqi ntawm lwm yam xws li manganese, phosphorus, thiab sulfur kuj txawv me ntsis. Cov ntsiab lus no raug kho kom ua tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv. Piv txwv li, qis qis ntawm phosphorus thiab sulfur yog qhov zoo rau kev txhim kho cov ductility thiab weldability ntawm cov hlau.
DX51 txhais li cas?
DX51 yog ib hom kub - dip galvanized steel khoom qib, thiab nws yog feem ntau txhais nyob rau hauv European tus qauv EN 10346. Ntawm no yog ib tug ncauj lus kom ntxaws qhia txog dab tsi nws sawv cev:
1. Kev faib tawm dav dav
Nws belongs rau qeb ntawm tsis tu ncua kub - dip galvanized ca khoom ntawm steel rau txias sib sau. Qhov no qhia tau hais tias cov hlau tuaj yeem ua tau los ntawm txias - txoj kev ua haujlwm tom qab kub - dip galvanizing txheej txheem.
Dab tsi yog qhov txawv ntawm DX51D thiab DC51D?
DX51D: Nws tau txhais nyob rau hauv European tus qauv EN 10346. Nws yog hais txog qhov kub tsis tu ncua - dip galvanized ca cov khoom ntawm cov hlau rau txias sib sau. Qhov "D" thaum kawg qhia tias nws tau kub - dip galvanized, uas muab cov zinc txheej tiv thaiv ntawm cov hlau nto los tiv thaiv corrosion.
DC51D: Qib steel no tau txhais nyob rau hauv European tus qauv EN 10130. Nws sawv cev rau txias - dov qis - carbon steel ca cov khoom rau txias forming, kuj nrog ib tug kub - dip galvanized txheej (tus "D" denoting lub galvanized kho).
Dab tsi yog steel qib DX51D?
DX51D steel yog ductile heev thiab hloov tau. Nws yog siv nyob rau hauv complex dep -draught Cheebtsam thiab ua raws li BS EN 10346: 2015 tus qauv. Classification: Ductile thiab saj zawg zog structural steel. Khoom: Nruam kub -dip coated steel.
