Material 1.2343 Steel Equivalent
HS 2343 ESR-S steel, which is a 1.2343 steel equivalent material, belongs to electroslag remelting hot work die steel. It has uniform microstructure, excellent machinability and polishability, high toughness and high plasticity, high wear resistance, and overall hardening performance at high and low temperatures are both excellent. You can find 1.2343 steel equivalent to ASTM A681 H11 / ISO 4957 X37CrMoV5-1 / GB/T 1299 4Cr5MoSiV /JIS G4404SKD6 / FDAC from HITACHI
HS 2343 ESR-S (Material 1.2343 Equivalent) Heat Treatment
Soft Annealing:
820 to 860°C, after being heated through, cooling down to 600°C at a rate of 10°C/h with the furnace, then air-cooling, hardness max 230 HB.
Stress relief annealing: after rough machining, heating to 650℃ and holding for more than 2h, cooling down to 500℃ with the furnace, and then air cooling.
Quenching:
Preheating under a protective atmosphere to 500-600 ℃ for the first time, 820-860 ℃ for the second time, and finally heating to 900-1010 ℃
Quenching after being heated through at the quenching temperature for more than 30 minutes, hardness will be 50-55HRC.
Tempering:
Slowly heating to tempering temperature 560-600 °C after quenching, and it is recommended at least twice tempering. Achievable hardness: 42−50 HRC.
As a die steel supplier, we will do our best to meet all the needs of customers.
