Delivery Condition
EAF+LF+VD, Forged, Quenching + Tempering, Hardness 28-34HRC or 30-36HRC or as customized, Unmachined or Machined surface, UT 100% Passed
 
Characteristics
1. It is a kind of plastic mold steel widely used in the world, with good comprehensive mechanical properties, good hardenability.
It is easy to get the homogeneous hardness throughout the section for big dimension blocks.
2. Good polish ability, good toughness on the surface.
3. Delivered in Pre-hardening condition, used directly for making molds, that can guarantee good usability and avoid the deformation in heat treatment.
 
Applications
1. Making medium or large sized high precision plastic molds with long life.
2. Making low melting point alloyed die casting molds, like tin, zinc, lead.
 
Forging Technique

Heat Temperature	Start Forging Temperature	Finish Forging Temperature	Cooling Method
1120-1160 °C	1070-1110 °C	>=850 °C	Sand Cooling or Slow Cooling
