High Carbon steels SAW vuam hlau F7A / P4-EH14 thiab vuam flux weld fabrication jointing
Siv rau -40C tej yam yuav tsum tau ib puag ncig, shipbuilding, pipeline, steel qauv, hnyav machinery thiab lwm yam khoom siv vuam.
Dab tsi yog characieristics?
●Submerged arc vuam hlau rau 480MPa qib siab zog hlau; Nrog GXL-101 flux vuam, vuam arc combustion yog ruaj khov, yooj yim tshem tawm slag, zoo nkauj vuam dhau txoj kev.
●Cov hlau welded muaj cov khoom siv zoo thiab qhov siab dhau ntawm X-ray.
