Low-Alloy Steels Phau Ntawv Electrode E8015-G semi-submersible drilling platform vuam hlau kauj
Lub ntsiab tivthaiv yog 1.5% Ni, tsawg hydrogen sodium hom tes electrode, ntawm -50C kev khiav hauj lwm kub, qhov cuam tshuam toughness ntawm deposited hlau yog zoo heev.
Ruaj khov arc, tsis tshua muaj txaws, zoo molding, yooj yim slag tshem tawm
X-Ray kev ua tau zoo heev
