M3:2 (P23 Jet High-Speed Steel) or M3/2 is a high-performance tungsten-molybdenum family high-speed steel characterized by high hardness, excellent wear resistance, and retention of the cutting edge at elevated temperatures. Its greater content of molybdenum and vanadium than traditional high-speed steels yields better abrasion resistance, edge retention, and thermal stability. These characteristics render M3:2 particularly well-suited for high-extreme-wear applications, such as precision cutting tools and heavy-duty machining. ASP 2025 is a universal steel number for the remainingthe the world for industrial markets.
P23 Jet High-Speed Steel (HSS) is a high-grade powder high-speed steel that is designed for demanding applications requiring superior performance over time. This steel is produced in our factory through two innovative processes:
1. RS ESR Directional solidification Electroslag Remelting: This process ensures high-quality consistency and directional control.
2. Spray Forming: Produces an improvement in efficiency and therefore performance.
