High Cutting Performance with Cost Efficiency
M32 directional powder metallurgy high-speed steel is manufactured using spray forming PM technology, specifically developed for high-speed cutting, precision machining, and heavy-duty applications. It offers outstanding red hardness, wear resistance, and cutting-edge retention. With strict process control, M32 matches the performance of leading international brands while offering greater cost advantages-making it ideal for tools like drills, end mills, reamers, and complex dies.
1. Spray Forming Powder Metallurgy Process
M32 is produced through advanced spray forming combined with powder metallurgy, resulting in a fine and uniform microstructure with well-dispersed carbides. The alloy composition-rich in tungsten, chromium, vanadium, and cobalt-is optimized for performance under high temperature, high speed, and high load conditions.
Tungsten (W): Maintains hardness and wear resistance at elevated temperatures
Chromium (Cr): Enhances hardenability, oxidation resistance, and contributes to secondary hardening
Vanadium (V): Improves wear resistance and refines carbides; may slightly reduce grindability
Cobalt (Co): Increases thermal stability and extends tool life
2. Precision Heat Treatment
With tightly controlled heat treatment, M32 achieves hardness levels up to 66-68 HRC while maintaining toughness and dimensional stability-ideal for high-speed, high-load cutting environments.
1. Full-Process Quality Control
From powder selection to final inspection, M32 is produced under a comprehensive quality management system, ensuring consistent mechanical properties, microstructural uniformity, and dimensional precision in every batch.
2. International Standards Compliance
