Hot work steel 1.2343

タイトルまたは説明

LSS H*1 hot work tool steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used H*3 hot work tool steel . This provides for the higher toughness , with some reduction in wear resistance and temper resistance . LSS H*1 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. LSS H*1 hot work tool steel is recommended for hot tooling applications where maximum resistance to cracking is required .Such applications include hot punches, dies casting dies , foring dies, hot shear blades, hot gripper dies , and extrusion tooling.
