Different kinds of cutting agent containing 0.4% of FC0205 powder were added on the basis of FC0205 powder to compare their effects on material properties. The forming density of the sample was 7.0 g/m³.
I. Effect on mechanical properties
Impact on cutting performance: TD-3 and TD-4 have greatly improved the cutting performance of the material.
Cutting test conditions:
Sample diameter Φ70mm, hole to hole spacing of 3mm, 19 holes drilled per sample.
Third, the effect on the microstructure: no effect on the metallographic organization, pearlite content normal.
Contains no cutting aids Contains MnS
