Description
W18Cr4V is tungsten series high-speed steel with high hardness, red hardness and high-temperature hardness. The heat treatment range is wide, quenching is not easy to overheat. The heat treatment process is not easy to oxidize and decarburize. The grinding performance is good. The hardness of the steel is maintained at HRC63-64 and HRC62-63 at 500 ℃ and 600 ℃ respectively. It has a good cutting performance.

Heat treatment
(1) forge: 1200～1250 DEG C of heating-up temperatures, 1050～1100 DEG C of initial forging temperatures, final forging temperature 850-900 DEG C, air cooling after forging;
(2) annealing: 900 DEG C of heating-up temperatures, insulation 2～4h, 720 DEG C of isothermal temperatures, are chilled to 500 DEG C with the speed stove of 5～10 DEG C/h, the air cooling of coming out of the stove after insulation 4～6h;
(3) quenching and tempering: 860～870 DEG C of quenching temperatures, oil quenching, then 720-760 DEG C of lonneal 2-4h tempering.
Features and Application
W18Cr4V steel is a widely used tungsten series general-purpose high-speed steel. It is easy to grind.
- It is used for tools that can still maintain cutting performance when the working temperature is below 600 °C. Such as turning, planing, milling, reaming, broaching, drills, various gear tools, taps, and dies.
- Suitable for processing soft or medium hardness (below 300 ~ 320hb) materials.
- Production of high temperature wear-resistant mechanical zero
