H13

 

1.Main application

Full hardness(HRC52-54)plastic moulds with high polishing and long service life requirements, such as Bakelite plastic moulds, Tin,lead,Zn and Al alloy die casting mould(such as engine radiator, lights and other decoration products), Aluminum extruded moulds(such as Aluminum window frame, computer radiator), hot forging moulds(such as car connecting bar, crank, stainless dinner knife), Cu alloy extruded, die casting moulds.

 

2.Delivery condition

Conventional or ESR, hot rolling or forging, black surface or Polishing

Hardness: ≤229HB

Width: 305~1000mm Thickness:20~300mm

 

3.General

ESR steel, high cleanliness, homogeneous microstructure, better heat resistance and toughness;good resistance to high temperature metal abrasion, better high tempering resistance, hardness steady working under 600. low dimensional distortion. good heat-checking resistance, and cold/heat fatigue resistance
