Kev ua tau zoo ntawm S420N siab yield zog steel phaj
S420N siab zog phaj yog lub siab muaj zog qis alloy steel phaj, teej tug mus rau European tus qauv EN10025 series ntawm cov qauv hlau, nrog rau cov yam ntxwv zoo heev thiab ntau yam kev siv.
S420N siab zog alloy steel kev ua tau zoo yam ntxwv
Zoo weldability: S420N siab zog phaj muaj vuam zoo thiab tuaj yeem txuas tau los ntawm ntau txoj kev vuam, xws li arc vuam, roj vuam, thiab lwm yam.
Kev ua haujlwm txias thiab kub zoo heev: S420N cov hlau tsis tshua muaj hlau qhia tau zoo thaum lub sijhawm ua haujlwm txias thiab kub, thiab yooj yim rau kev ua haujlwm xws li khoov, curling, thiab shearing .
S420N siab zog tsawg alloy steel daim ntawv thov thaj chaw
Cov nkoj loj: siv los tsim cov khoom tseem ceeb xws li keels thiab tav ntawm cov nkoj.
Cov choj thiab cov khoom siv fais fab chaw nres tsheb: xws li cov choj loj, kev tsheb ciav hlau, thiab cov khoom thauj khoom ntawm cov chaw nres tsheb fais fab, thiab lwm yam.
Nruab nrab thiab siab siab boilers thiab cov hlab ntsha siab: siv los tsim cov thawv thiab cov khoom siv uas tiv taus siab thiab kub.
