Principal Feature:
AISI H11 / 1.2343 tool steel is a 5% chromium hot work steel that is characterized by excellent impact toughness. H11 steel contains less vanadium than the widely-used H13 hot work tool steel. AISI H11 die steel is a deep-hardening, air-hardening steel that exhibits minimal size change during heat treatment. H11 / 1.2343 steel has good resistance to thermal fatigue cracking (heat checking) and excellent resistance to gross cracking and thermal shock when water cooled in service. AISI H11 /1.2343 die steel is recommended for hot tooling applications where maximum resistance to cracking is required.
1.2343 Typical Application:
Hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies and extrusion tooling.
1.2343 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)
