Qhov no tso cai rau cov hlau siv ncaj qha rau hauv cov txheej txheem tshuaj feem ntau hauv kev ua -welded mob yam tsis tas yuav tsum tau ua haujlwm nyuaj- vuam cua sov.
Zoo heev Resistance rau Localized Corrosion
Cov nyhuv synergistic ntawm ntau dua molybdenum (4-6%) thiab tungsten (1.5-4%) cov ntsiab lus muab kev ua haujlwm zoo rau pitting thiab crevice corrosion. Nws ua haujlwm ruaj khov hauv cov cheeb tsam acidic uas muaj halide ions xws li chloride thiab fluoride, ua haujlwm tau zoo dua ntau cov hlau tsis huv.
Zoo Formability thiab Weldability
Nws tuaj yeem tsim los ntawm cov txheej txheem ua haujlwm kub thiab txias thiab nthuav dav weldability zoo (tsim rau GTAW, GMAW, SMAW, thiab lwm yam). Nrog rau kev tswj vuam kom zoo, tom qab- vuam vuam tsis tas yuav tsum tau kho, ua kom yooj yim rau kev tsim cov khoom siv.
