Sintering carbon loss usually at the level of 0.15~0.25wt% for these alloy powder materials.
- Sintered surface is very smooth by using HJ’s MIM powder material design.
- With very fine and uniform crystal structure, sintered grain size can reach or higher than grade 7.
440C 烧结态,烧结密度:7.73g/cm3 ,晶粒度>7级 440C 热处理后,晶粒度>7级
