Latrobe LSS™ H12 Hot Work Tool Steel (ASTM H12)

 

Subcategory: Tool Steel; Hot Work Steel; Alloy Steel; Metal

Close Analogs: Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.

Material Notes:
TLS H12 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 H13 hot work tool steel, and the tungsten content provides better temper resistance. TLS H12 hot work tool 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 checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. TLS H12 hot work tool steel is recommended for hot tooling applications where maximum resistance to cracking is required. Such applications include hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling.
