DIN 30CrNiMo8 karfe

DIN 30CrNiMo8 karfe karfe ne wanda aka tsara don ƙirƙirar samfuran farko.

• DIN 30CrNiMo8 abu ne guda tsarin karfe tare da matsakaita taurin da aka ƙera don kayan aikin nauyi mai nauyi, wanda ke da girman elasticity da kaddarorin ƙarfi wanda ya kai 1560 N / mm2 a ƙananan diamita. Lokacin da aka yi laushi, taurin ya kai max. 248 HRB.
• Hakanan ana siffanta ta  juriya ga mabambantan nauyi da tasiri.
• Duk da haka, ba shi da kyau don waldawa kuma yana buƙatar ƙarin preheating.

Gnee yanzu yana haja 30CrNiMo8 karfe zagaye mashaya don jigilar kaya kai tsaye tare da ingantaccen inganci da samun diamita gama gari. Zafafan birgima ko zafi da aka yi wa zagaye mashaya duka suna samuwa. Ga wasu cikakkun bayanai na 30CrNiMo8:
