Hot and Warm Forging Die Steel
QUICK NAV
- Applicable with the maximum hardness of 58HRC
- High hardness and tough grade with excellent heat checking resistance
- Fine microstructure as that of hot work die steels resulting in higher toughness than conventional high speed tool steels
- High softening resistance and hot hardness
- Double melting realizes clean and homogeneous steel with less non-metallic inclusions
