How about M42 high speed steel cutter with tungsten carbide cutter hardness, suitable for processing what material?
High speed steel milling cutter hardness about HRC68, suitable for stainless steel, carbon steel, tool steel, etc.;The hardness of tungsten steel milling cutter was about HRC72, in addition to the above, can also be processed alloy material.
The hardness of cemented carbide is not expressed by HRC. It should be HRA. The hardness of cemented carbide can reach HRA94, but the hardness of HRC is 82
Hello, this problem I am professional, M42 high-speed steel milling cutter limit hardness of about HRC68, suitable for processing carbon steel, alloy steel, stainless steel, cast iron, etc., all the hardness of less than HRC45 of materials.The true hardness of HRC90 tungsten steel, downstairs is a fart. Suitable for machining of high speed steel, alloy steel, carbon steel, hardened steel, high hardness of the material is not more than HRC70.To the landlord said, tungsten steel is not steel, called hard alloy. It is obtained from tungsten carbide and cobalt by powder metallurgy.Hope to help you, do not understand, you can ask again.
