Properties :
Hot work tool steel with high resistance to thermal shocks and fatigue, good thermal conductivity, hot tensile and impact
strength, resistance to tempering, fine grain size with high toughness, extra fine structure without grain boundary
carbide, high creep strength at elevated temperature, insensitive to constant temperature change, low P and S content,
suitable for water cooling. This grade can be produced on request by the process EFS, ESR or VAR.
Furnaces for metallurgical processing:
electrode arc + LF/VD/VOD/ESR/Vacuum consumable electrode.
Ultrasonic inspection: 100% ultrasonic inspection for any inperfections or based on the customer's requirement.
