Alloy Steel Peev Casting

Kev piav qhia

Kev nqis peev casting yog ib qho txheej txheem casting. Cov hom alloys uas tuaj yeem tsim los ntawm peev casting yog carbon steel, alloy steel, tshav kub-resistant alloy, stainless hlau, precision alloy, ruaj hlau nplaum alloy, bearing alloy, tooj liab alloy, aluminium alloy, titanium alloy thiab ductile hlau. Cov txheej txheem casting peev yog complex thiab nyuaj rau kev tswj, thiab cov ntaub ntawv siv thiab noj yog kim, yog li nws yog tsim nyog rau zus tau tej cov me me qhov chaw nrog complex zoo, siab precision yuav tsum tau, los yog nyuaj rau nqa tawm lwm yam kev ua.

Nta

No Alloy Steel Peev Casting yog ib hom nruab nrab hardened steel nrog zoo processability, me deformation thiab zoo qaug zog kuj. Tom qab kev kho cua sov, cov khoom lag luam muaj lub zog zoo thiab cov khoom siv txhua yam. Nws qhov siab tshaj plaws ua haujlwm kub yog 427 degree C. Cov khoom muaj lub zog siab, siab quenching muaj peev xwm, zoo toughness, me deformation, siab creep zog thiab kub endurance zog. Nws yog siv los tsim cov forgings nrog lub zog siab dua 35CrMo steel thiab siab dua ntu ntu zoo, xws li cov iav loj, lub zog tsav lub zog, lub qag nram qab, cov kabmob txuas thiab lub caij nplooj ntoos hlav clip, nrog rau cov pob qij txha, cov cuab yeej nuv ntses thiab khoov tshuab tuag rau qhov tob. qhov dej hauv qab 2000m.
