H12/1.2602 Hot Work Die Tool Steel
H12 steel is a type of hot-work tool steel with high chrome and vanadium content. It is known for its excellent toughness, wear resistance, and thermal conductivity, making it suitable for use in high-temperature applications such as forging, aluminum die-casting, and extrusion. H12 steel is also resistant to thermal fatigue and can maintain its strength even at high temperatures. It can be hardened by heat treatment and has good machinability.
