KT5331AS0 and 45 Steel Milling Comparison of Surface Characteristics
To study the surface composition, hardness, microstructure of the machined surface in KT5331AS0 and 45 steel at different cutting parameters and cooling conditions. The results show that: in the cutting process the mass fraction of W in KT5331AS0 steel surface were reduced to varying degrees, the basic chemical composition of 45 steel surface did not change; When KT5331AS0 steel in the high-speed, higher feed rate, it will be cause surface hardness increasing, however the hardness of 45 steel have no regular variation; 45 steel will have greater depth of the torn surface after milling, tearing a wider range, more obvious surface oxidation.
