1. Features:
(1) With excellent machinability, hardened, the size is extremely stable, hardened, the surface has a very high hardness.
(2) With a high toughness, so excellent anti-wear ability and easy forging and quenching.
(3) Can be widely used in cutting, cold stamping and forming tools; such as notch die, cold stamping die, various gauges, reamers,
mold bushings and plastic small modules.
(4) Annealing hardness:230HB
2. Application
(1) Use to create a large cross-section and complex shape of the cold die, and a variety of measuring tools.
(2) Commonly used in punching die, stamping die, bending die, drawing die, punch punch, fine mold, and other metal molds.
