Powder-metallurgical high-speed steel, fine distributed carbide structure,
high compressive strength, excellent toughness, high wear resistance, high thermal stability.
The volume of carbides is a little bit higher, compared to PMD23
Cold work tools for punching and cutting, precision blanking tools,
cold extrusion and deep drawing dies, coining tools. Also for machining tools ,
like milling cutters, broaches etc.
