High Carbon steels SAW vuam hlau F7A / P6-ECG thiab vuam flux weld fabrication khoom
Siv rau -50C tej yam yuav tsum tau muaj ib puag ncig, feem ntau yog siv rau shipbuilding, pipeline, siab nkoj vuam.
Dab tsi yog characieristics?
●Hlau hmoov core submerged arc vuam hlau rau 480MPa qib siab zog steel; Nrog GXL-121 flux vuam, vuam arc combustion yog ruaj khov, yooj yim tshem tawm slag, vuam dhau txoj kev zoo nkauj.
●Lub vuam hlau muaj cov khoom siv zoo heev, cov ntsiab lus tsis tshua muaj P thiab S, thiab kev ua haujlwm kub tsis zoo.
