M2 HIGH-SPEED TOOL STEEL
OF MAKING TOOLS
|M2 can be worked in
the same way as other high-speed steels by plastic forming, machining,
grinding, electrical discharge machining, welding and polishing.
M2 is amenable to cold forming.
In grinding, local heating of the surface, which might alter the microstructure, must be avoided. Grinding wheel makers can supply advice on the choice of grinding wheels. Machining is carried out using carbide or high speed steel tools.
|The bend strength is a measure of the toughness of the material. It will be seen from the diagram that toughness and hardness can be controlled by varying the hardening temperature.|
