Applications:
1. Cutting Tools: 1.2493 steel is extensively utilized in the production of cutting tools, including knives, blades, and shear blades. These tools are employed in the precision cutting and shaping of diverse materials such as metals, plastics, and rubber.
2. Forming Dies: This steel is pivotal in manufacturing forming dies used in cold forming and shaping processes like bending, drawing, and extrusion, ensuring reliable performance and durability.
3. Cold Work Applications: Owing to its high hardness, exceptional wear resistance, and robust toughness, 1.2493 steel is indispensable in various cold work applications requiring precision machining and high dimensional accuracy.
4. Punching Tools: 1.2493 steel is essential in crafting punching tools used for perforating or stamping a variety of materials, including sheet metal and plastics, delivering dependable and consistent results.

Heat Treatment:
Annealing: To achieve complete annealing, uniformly heat 1.2493 steel at 800-850°C (1472-1562°F), hold it at that temperature for an adequate time, and then cool it slowly in the furnace to below 600°C (1112°F).
Quenching: Gradually preheat the steel to the austenitizing temperature range of 980-1020°C (1796-1868°F), then quench it rapidly in oil or air to attain full hardness.
Tempering: Immediately following the quenching process, temper the steel at 180-220°C (356-428°F) for 2 hours, and then allow it to cool in the air. This process optimizes the steel’s balance of hardness and toughness.
