| Characteristics |
High strength, good hardenability
High abrasive resistance and small shock load
Very high wear resistance against abrasive and adhesive wear
Medium toughness
Dimensionally stable
High compressive strength |
| Applications |
High performance cutting tools for steet upto 4mm thickness,trimming dies,blanking dies for paper and plastic ,shear blades for cutting light gauge materialthreat rolling dies,drawing,deep drawing,pressure pads and highly wear-resistant plastic moulds |
| Heat Treatment |
Along with the furnace cooling after(850~870) °C× (3~4)h . (740~760)°C×(4~5)h,out air cold
Low impact toughness and should avoid tempering at about 950~1150°C |
