describe in detail:
Features: Steel for die-casting molds and stamping molds
Quenching temperature:1000-1050℃
Cooling method: air-cooled or air-cooled
Tempering temperature and hardnessHRC
200 300 400 500 600 650
 -   -   51  53  50  38
Main application: Large die-casting molds
Specification and model:Round rod, flat plate full
talent:
Extremely good hardenability, especially good toughness when used for large molds(be relative toSKD61)
Extremely good resistance to heat fatigue cracking(be relative toSKD61)
Good heat resistance and melting resistance(be relative toSKD61)
High machinabilitySKD61Slightly reduced。
purpose:
purpose hardness purpose hardness
AL MgDie casting mold 4350HRC Hot pressing mold(Steel, copper) 4550HRC
Die casting mold components(Injection cylinder, injection punch) 4550HRC thermal shear 4050HRC
AL
Hot extrusion die 4550HRC Cold forging die 5052HRC
The hardness requirements for hot work mold steel are appropriate, with a focus on red hardness, thermal conductivity, and wear resistance. Therefore, the carbon content is low, and the alloying elements mainly increase hardenability, improve wear resistance, and red hardness。
