16MnCr5 kub dov steel puag ncig tuav

16MnCr5 steel yog alloyed case hardening engineering steels rau qhov chaw uas yuav tsum tau core tensile zog ntawm 800 - 1100 N / mm² thiab zoo hnav tsis kam. Nws yog cov khoom siv engineering feem ntau siv los tsim cov piston bolts, camshafts, levers thiab lwm yam tsheb thiab cov khoom siv tshuab engineering.
EN 1.7131 steel (16MnCr5 khoom) yog ib qho European txheem carburized steel (cov ntaub ntawv hardening steel) nrog zoo hardenability thiab machinability. Rau qhov loj hla ntu, qhov tawv tawv tawv thiab hnav tsis kam tuaj yeem tau txais tom qab kev kho cua sov, thiab qhov kub tsis tshua muaj kev cuam tshuam toughness kuj siab. Rau specification thiab datasheet, thov mus saib cov lus hauv qab no.
16MnCr5 steel feem ntau yog siv tom qab carburizing thiab quenching, thiab feem ntau yog siv rau kev tsim cov iav, worms, sealing bushings thiab lwm yam khoom.
