In general we are in the midst of a temperature of 200 to 850 degrees to the use of heat resistant steel for homework, of course, the knowledge in before we do some simple use of heat-resistant steel parts, but now heat resistant steel from our life is getting closer, in all walks of life can see his shadow.Heat resistant steel is lively, so at the time of cutting and cutting tools produce certain reaction, this will impact on the surface of the processed parts still can let flake knives.Heat resistant steel cutting chip that can arise when it is easy to plugging tool, for this will make the parts surface smoothness is reduced, still can let tool occurrence collapse edge.In the form of heat resistant steel he is more complex, so there will be a discontinuous chip, the tool will cause certain damage.
