30CRMOV9 / 1.7707 Alloy simbi

30CrMoV9 isimbi iyo kazhinji inogadzirirwa kugadzirwa kwezvikamu zvakadzimwa uye zvine hasha, izvo zvinowanzogadzirwa uye zvinozoitwa nitrided. Iyo alloy 30CrMoV9 inowanzogadzirwa neEAF /VD /LF ichiteverwa ne electroslag refining (ESR) kana zvichidikanwa kune chinangwa chakakosha. Mabhawa uye, pazvinoshanda, forgings inoitwa ultrasonic bvunzo zvichibva padanho rakasiyana zvinoenderana nezvinodiwa nevatengi. Mabhawa anowanzo kupihwa anopenya mu annealed condition, kana kupenya annealing kunyanya.
