1. What is M2 high speed steel powder?
M2 is a tungsten-molybdenum high-speed tool steel commonly used for cutting tools and wear-resistant tooling. In powder form, it can be processed using additive manufacturing, powder metallurgy, MIM, and other powder-based technologies.
2. What is the difference between M2 and M4 high speed steel?
M2 contains approximately 2% vanadium, while M4 has a substantially higher vanadium content. M4 is generally selected when greater wear resistance is required, while M2 offers a widely used balance of toughness, hardness, wear resistance, and cost.
3. Can M2 HSS powder be used for additive manufacturing?
Yes. Gas-atomized spherical M2 powder can be used for certain additive-manufacturing processes. The required particle-size distribution, flowability, apparent density, oxygen content, and morphology should be matched to the specific AM equipment.
4. What particle size is recommended for M2 powder?
The appropriate PSD depends on the manufacturing process. Fine spherical powders may be suitable for LPBF, while larger particles can be used for other powder-processing techniques. REG Metals can source custom particle-size distributions based on the customer's equipment.
5. Can M2 HSS powder be heat treated?
Yes. M2 is designed to develop high hardness and wear resistance through appropriate hardening, tempering, and heat-treatment cycles. The final properties depend on powder processing, consolidation method, heat treatment, and component geometry.
6. Can REG Metals provide COA documentation?
Yes. Certificates of Analysis and available technical documentation can be provided as applicable, including chemical composition and powder characteristics supplied by the manufacturer.
