Principal Feature:
1.2343 steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. It contains less vanadium than the widely-used H13 hot work tool steel. 1.2343 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.1.2343 steel is recommended for hot tooling applications where maximum resistance to cracking is required.
Typical Application:
Hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies and extrusion tooling.
Heat Treatment:
Forge: at 1050℃-1095℃ Cool slowly and anneal then.
Annealing: at 843℃-898℃ Cool slowly in furnace
Stress Relieving: heat slowly to 566-676℃, and then cool in still air.
Hardening: Preheat to 815 ℃ and then heat to 1010℃ and hold for 15 to 40 minutes. Air cool (air quench)
