Low-Alloy Steels Phau Ntawv Electrode E7016-C2L Reactor Cheebtsam Weld
Lub ntsiab muaj pes tsawg leeg yog 3.5% Ni steel, tsawg hydrogen potassium hom tes vuam pas nrig, ntawm -75C kev khiav hauj lwm kub, nws melting
Qhov cuam tshuam toughness ntawm cov hlau yog zoo heev.
Arc ruaj khov, tsis tshua muaj txaws, zoo molding, yooj yim slag tshem tawm, X-Rav kev ua tau zoo heev.
