All – Purpose Hot Work Steel H 13 Properties & Applications
H13 is the hot work tool steel with good toughness and high temperature resistance. It also owns excellent cutting and polishing performance. After electro-slag remelting, the quality is much better. This grade has found wide acceptance for extrusion dies for aluminum, zinc and copper, die casting molds, forging dies and hot shear blades. It is also an excellent steel for plastic
Hot Work Steel H 11
It is a SKS series steel applied in hot rolling metal mold. It is characterized by excellent impact touchness. It has good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. Its applications include hot punches, casting dies, forging dies, hot shear blades, and extrusion dies.
Hot work tool steel with tungsten H 21
H 21 is a hot work tool steel recognized by its high heat resistance, excellent wear-resistance and excellent processing property, exhibiting nice stability in heat treatment. It remains dependable when the temperature is up to 650◦C. H21 is particularly useful for hot forging and blanking dies and punches for making nuts, bolts and other similar small components.
Forming dies, shear blades, hot extrusion dies, mandrils, die holders, and extrusion liners are also prime applications for this steel
