1.3207, HS10-4-3-10 - specification and application
Tungsten-cobalt-vanadium high-speed steel with very high resistance to abrasion and tempering, high strength at high cutting speeds and hardness above 65 HRC after machining. Steel designed for tools for rough and finishing machining of difficult steels, austenitic stainless steels and materials with high mechanical properties. It has a tendency to decarburize, particularly low impact strength, low ductility, difficult in polishing. Grade used for high-performance milling cutters, planer knives, turning knives, shape knives for automatic machines and peelers.
Mechanical properties of 1.3207, HS10-4-3-10:
- Softened annealed condition +A: 241-302HB
- Delivery condition +A+C: <352HB
