Features
Chemical Composition
Heat Treatment
General Applications
Die casting, forging, extrusion and pressing dies, shear blades, sleeves, plunger and etc.
It has air hardening with good toughness, resistance to abrasion and high red hardness. It resists softening to 550°C and has good resistance to heat checking. Will Nitride with a case hardness over 1000 V.P.N. Generally supplied annealed to HB 230 max.
Features
- 1 Electroslag remelting steel, high purity, good resistance to dissolve
- 2. Organizational structure of uniform, better heat resistance with good toughness, high temperature resistance metal erosion
- 3. Good resistance to high temperature tempering performance, hardness steady working under 600ºC, dimensional accuracy stability durability.
- 4. Cold and hot fatigue resistance, strong ability to resist crack.

| Heat Treatment | H13 / 1.2344 / SKD61 steel Annealing: 750 to 800ºC, slow cooling in furnace (10-20ºC/hr), down to 600ºC, cooling in air. Hardness after annealing: max. 230 HB. Stress relieving: 600 to 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours. Hardening: 1020 to 1080ºC, oil/air, hold 20 to 30 minutes. Hardness , 52 to 56 HRC in oil, 50 to 54 HRC in air. Tempering: 560 to 580ºC. Slowly heating to tempering temperature right after hardening. Recommended to temper at least twice. The second tempering temperature shall be approx. 20 to 30ºC lower than the first tempering. | ||
