30CRMOV9 / 1.7707 URUBUGA RWA ALLOY

30CrMoV9 nicyuma muri rusange kigenewe guhimba ibice byazimye kandi bifite ubushyuhe, mubisanzwe bikozwe hanyuma bigahita bitangwa. Amavuta 30CrMoV9 mubusanzwe akorwa na EAF / VD / LF ikurikirwa no gutunganya amashanyarazi (ESR) nibiba ngombwa kubwintego idasanzwe. Utubari kandi, aho bibaye ngombwa, kwibagirwa gukorerwa ibizamini bya ultrasonic ukurikije urwego rutandukanye ukurikije ibyo abaguzi basabwa. Ubusanzwe utubari dutangwa neza muburyo bwa annealed, cyangwa urumuri rwihariye.
