Vanadis 10 structural steel is a premium powder metallurgy (PM) tool steel renowned for its exceptional combination of wear resistance, toughness, and red hardness. Unlike conventional cast tool steels, which can suffer from large, irregular carbide formations, Vanadis 10 is manufactured using advanced powder metallurgy. This process produces a material with an extremely fine, uniform distribution of hard vanadium and tungsten carbides. This unique microstructure provides a balance of properties that is difficult to achieve in cast steels: very high hardness (60-64 HRC) for exceptional wear resistance, good toughness to resist chipping, and excellent red hardness to maintain its properties at elevated temperatures. For demanding applications such as high-speed cutting tools, cold work dies, and precision stamping tools, Vanadis 10 offers a superior level of performance and reliability.
Introduction
For decades, the performance of tool steels has been limited by the manufacturing process. Cast tool steels, such as D2 or M2, often contain large, irregular carbides that can act as initiation points for cracks and can make the material prone to chipping. As industries demand higher productivity, longer tool life, and the ability to machine harder materials, the limitations of conventional tool steels become increasingly apparent. Vanadis 10 was developed to overcome these limitations. Its powder metallurgy production creates a steel with a uniform, fine-grained structure, free from the large carbide clusters that plague cast steels. This results in a material that is simultaneously harder, tougher, and more wear-resistant than conventional grades. For toolmakers and manufacturers seeking the highest level of performance, Vanadis 10 offers a proven and superior solution.

Forming and Heat Treatment
- Hot Rolling: The powder metallurgy billets are hot rolled into bars and plates.
- Annealing: Before machining, the steel is annealed to a softer state (HB 280-320) to make it easier to shape.
- Heat Treatment: This is critical to achieving final properties.
- Quenching: Heated to 1020-1060°C and rapidly cooled in oil to harden the steel.
- Tempering: Reheated to 500-550°C to reduce brittleness while maintaining high hardness (60-64 HRC).
Finishing
- Machining: In the annealed state, Vanadis 10 is machined using carbide tools .
- Grinding: After heat treatment, precision grinding with CBN (cubic boron nitride) or diamond wheels is used to achieve final dimensions and sharp edges.
- Coating: For cutting tools, a PVD coating such as TiAlN (titanium aluminum nitride) is often applied to reduce friction and further extend tool life.
