● Steel properties:
HPM38 13 chrome series stainless steel containing molybdenum, after a special solution made ??of. Therefore the most suitable and high hardness and corrosion-resistant surface of the plastic mold demanding. And it is a very small thermal deformation, it is also suitable for heat treatment and precision. In addition, the erosion of good maintenance is very favorable for mold.
* Mirror finish is very good
* Has a better wear resistance than SUS420J2 corrosion, no chrome
* Delivery of pre-hardened state, it can be used immediately
* Suitable for precision mold
● Chemical Composition:
13 Ming-molybdenum stainless steel patent
● Delivery status: Pre-hardened to 29-33HRC
Quenched hardness after annealing up to 50-55HRC
● Application:
For corrosion and heat processing of precision plastic mold steel mirror
* Transparent mold products: lenses, dressing, etc.
* Flame-retardant resin molds: home appliances, office equipment, communications equipment, spare parts
* Electroless Products: Food curtains containers, medical equipment
● Heat treatment:
Quenching 1000-1050 cooled
Tempering 200-500 cooled
