● Steel properties:
  HPM7 is pre-and medium-sized with the die hard steel, both were excellent and very good cut welding, colleagues and well-mirror processing, discharge processing,
  Level is 29-33HRC the best pre-hardened steel.
      * Large cross-section hardness of the material is distributed more uniformly (29-33HRC)
      * To be cut faster than the average of the CSM Department of steel and steel cutting good
      * Excellent welding, soldering and welding cracks in the phenomenon of hardness less
      * Have a good mirror finish
      * EDM rarely produce stripes after the organization, the hardness of the surface hardening of low, easy post-processing
      * With super toughness
      * Has good features nitride
● Chemical Composition:
              Patent pending

● Delivery status: Pre-hardened to 29-33HRC
            
● Application:
      Commonly used in large-scale precision plastic mold steel mold
      * Auto parts: mirrors, tail lights, instrument panel
      * Appliances, office automation products, home equipment: TV, air conditioning, wash room
      * Other bulk commodities such as large machines, tubes, rubber mold
