Tsika Chrome Molybdenum 42CrMo4 alloy simbiinvestment casting productsyekukiya chirauro chemota neelectrophoresis pamusoro kurapwa.
42CrMo4 (1.7225) kubva kutsanangudzo ye EN 10083-3, iyo inowanzo kupisa kupisa neQT (Queching + Tempering), inoshandiswa zvakanyanya kugadzira mari yekukanda. Iine simba repamusoro, kusimba kwepamusoro, kuomarara kwakanaka, kushatirwa, kukwirira kuneta, kugadzikana kwakanaka kwekudzivirira mushure mekudzima uye kudziya, uye yakanaka yakaderera tembiricha inokanganisa kuoma. Iwo akaenzana giredhi re42CrMo4 ari 4140 (ASTM, USA) uye 42CrMo (GB/T 3077, China)

Kushandisa theinvestment casting process, RMC casting foundry inokwanisa kusangana nezvinhu zvinoenderana neASTM, SAE, AISI, ACI, DIN, EN, ISO, uye GB zviyero. Tine anopfuura zana akasiyana ferrous uye asiri-ferrous alloys ayo isu tinokandira zvikamu tichishandisa yakaoma dhizaini maitiro. Yedu dimensionally uye geometrically yakaoma investment castings inogadzirwa kune mambure chimiro, kuderedza kudiwa kwechipiri machining.
Chromium-molybdenum cast simbi inoshandiswa zvakanyanya muminda yemaindasitiri ine yakakwira michina zvivakwa. Kuwedzerwa kwe molybdenum kune chromium simbi kunogona kuwedzera kusimba kwesimbi yekukandira pasina kuve nekukanganisa kwakakosha pakusimba kwekusimba kwesimbi yakakandwa. Uyezve, chromium-molybdenum yakakandwa simbi ine yakanyanya kunaka tembiricha yekuita uye inokambaira kuramba. Mushure mekudzima uye kudzikisira kana kujaira kupisa kurapwa, chromium-molybdenum yakakandwa simbi inogona kuwana yakanakisa mechaniki zvivakwa.
Molybdenum inogona kuvandudza kuoma kwesimbi yakakandwa uye kuderedza hasha brittleness yesimbi yakakandwa. Chromium-molybdenum cast steel inoshandiswa kune yakakura-chikamu castings uye simbi castings inoda kuomeswa kwakadzama.
