SS400 cov pa roj carbon phaj li cas?
SS400 STEEL PHAJ yog cov qauv siv roj carbon tsawg uas tau ntsib Japanese tus qauv JIS G3101. Nws muaj qhov tsawg kawg tensile lub zog ntawm 400 MPA thiab yog tus cwj pwm los ntawm kev ua ib qho kev lag luam thiab cov khoom siv dav dav. Ua tsaug rau nws lub zog siab, lub zog ruaj khov thiab nws yog dav siv hauv kev tsim kho, txuas hniav, txua nkoj thiab cov kev siv tshuab ua lag luam.
Dab tsi yog S235JR cov pa roj carbon hlau?
S235JR yog ib qib ntawm cov qauv hlau teev hauv European Cov Qauv Kev Kawm Ntawv EN 10025-2.
Tsab ntawv "S" qhia tias "cov qauv hlau."
Tus lej "235" yog hais txog qhov tsawg kawg nkaus los lub zog muaj zog ntawm 235 MPa.
Lub "Jr" Suffix txhais tau tias cov khoom tau dhau ib qho kev sib tw charpy cuam tshuam thaum 20 degrees.
Qhov no txo cov pa roj carbon, no tsis-alloy steel muaj cov qauv weldability zoo heev xws li nws feem ntau siv nyob rau hauv cov ntawv thav duab thiab cov tsheb ciav hlau thiab cov tsheb ciav hlau dav dav.
Qhov sib txawv ntawm SS400 thiab S235JR
