Features of 9CrWMn Steel

  • It has certain hardenability and wear resistance, small deformation after quenching, uniform carbide distribution and fine particles.



Application of 9CrWMn Steel

  • It is used to make cold stamping dies with small cross-sections, more complex shapes  and high-precision.

  • It is used to make thin stamping dies, decorative embossing dies, etc.

  • It is used to make cutting tools with small deformations and long, complex shapes, such as pullers, long taps, long reamers and special milling tools.

  • It is used for integrally hardened plastic molds.

  • It is used for thermosetting plastic forming molds, requiring high wear resistance and high strength.
