Dab tsi yog high manganese steel?

High-manganese hlau yog melted los ntawm ib tug induction melting rauv, thiab melting kub yog siab li 1800 ° C. Tom qab casting, nws yog cam khwb cia rau hauv hnav-resistant qhov chaw ntawm ntau yam duab. Nws muaj li ntawm 1.2% carbon thiab 13% manganese. Tom qab quenching hauv dej ntawm 1000-1050 ° C, tag nrho cov qauv austenite tuaj yeem tau, yog li nws tseem hu ua austenitic siab manganese hlau.

High manganese steel muaj zoo toughness thiab muaj zog nyiam ua hauj lwm hardening, thiab qhia superior hnav tsis kam nyob rau hauv tej yam kev mob. High manganese steel yog tsuas yog siv los ua lub puab tsaig crusher hniav phaj, excavator thoob hniav thiab railway turnout.
