Steel properties :

1.2606 hot work tool steel is a 5% chromium, general-purpose hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used 1.2344 / H13 hor work tool steel. Steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment. It has good resistance to thermal fatigue cracking (heat cracking) and excellent resistence to gross cracking and thermal shock when water cooled in service.

______________________________________________________________________________________________________________

Applications :

 

Hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging die, hot shear blades, and extrusion tooling.
