Product Application

Kushandiswa kwe42CrMo alloy seamless pombi: simbi yakakosha inoshandiswa kumabhiriji "42CrMo", simbi yakakosha yemagidhi emotokari ndi "42CrMo", uye simbi yakakosha yemidziyo yekumanikidza ndi "42CrMo".Rudzi urwu rwesimbi runonatsiridza mashandiro esimbi nekugadzirisa kabhoni (c) zvirimo.Saka, maererano nekabhoni, rudzi urwu rwesimbi runogona kukamurwa kuita: low carbon steel -- kabhoni yemukati kazhinji iri pasi pe0.25%, senge 10 uye 20 simbi;Medium kabhoni simbi -- iyo kabhoni yemukati kazhinji iri pakati pe0.25 ne0.60%, senge 35 uye 45 simbi;Yakakwira kabhoni simbi -- iyo kabhoni yemukati kazhinji yakakura kupfuura 0.60%.Mhando iyi yesimbi haiwanzo shandiswa kugadzira pombi dzesimbi.

Typical Application
Inokodzera kugadzira hombe uye yepakati-saizi epurasitiki mold inoda imwe simba uye kuoma.
