Product Description
1.2550 Steel/6WCrV7 cold work tool steel :
1.2550 is a high-alloyed cold work tool steel known for its excellent wear resistance, high hardness, and good dimensional stability. It belongs to the group of high-alloyed chromium-molybdenum-vanadium steels and is commonly used in the manufacturing industry for producing cutting tools, forming dies, and other cold work applications.
Chemical Composition:
Properties:
1.High Wear Resistance: 1.2550 steel exhibits excellent wear resistance due to its high alloy content, making it suitable for applications involving abrasive wear and heavy loads.
2.High Hardness: Through proper heat treatment, 1.2550 steel achieves high levels of hardness, ensuring long-lasting cutting performance and dimensional stability.
3.Good Toughness: Despite its high hardness, 1.2550 steel retains good toughness, reducing the risk of fracture or failure during use.
4.Dimensional Stability: The alloy composition of 1.2550 steel provides it with good dimensional stability, ensuring consistent performance and accuracy in machining operations.
Applications:
1.Cutting Tools: 1.2550 steel is commonly used for manufacturing cutting tools such as knives, blades, and shear blades used in cutting and shaping various materials, including metals, plastics, and rubber.
2.Forming Dies: It finds application in the production of forming dies used for cold forming and shaping operations, such as bending, drawing, and extrusion.
3.Punching Tools: It is employed in the manufacturing of punching tools used for perforating or stamping sheet metal, plastics, and other materials.
4.Cold Work Applications: Due to its high hardness and wear resistance, 1.2550 steel is utilized in various cold work applications requiring precision machining and dimensional accuracy.
Heat Treatment:
Annealing: Heat uniformly at 750-800°C (1382-1472°F), hold for sufficient time, then slowly cool in the furnace to below 600°C (1112°F) for complete annealing.
Quenching: Preheat slowly to the austenitizing temperature of 850-880°C (1562-1616°F), then quench rapidly in oil or air to achieve full hardness.
Tempering: Immediately after quenching, temper at 180-220°C (356-428°F) for 2 hours, followed by air cooling to obtain the desired combination of hardness and toughness.
