Kev kho cua sov ntsig txog
- Annealingntawm 20CrNiMo Alloy qauv steel
Maj mam rhuab mus rau 850 degree thiab cia lub sij hawm txaus, cia cov hlau kom huv si, ces txias maj mam nyob rau hauv lub qhov cub. 20CrNiMo alloy steel yuav tau MAX 250 HB (Brinell hardness).
- Hardening ntawm 20CrNiMo Alloy qauv steel
Tshav kub maj mam mus rau 880-920 degree , Tom qab txaus soaking ntawm no kub quench nyob rau hauv roj. Kub kom sai li sai tau thaum cov cuab yeej ncav cuag chav sov.
