● 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
