Typical Heat Treatment and Quenching Process of W18Cr4V Steel
M23C6 begins to dissolve at 900°C and completely dissolves at 1090°C; M6C begins to dissolve at 1037°C, and the amount of dissolution above 1250°C gradually decreases; MC1100°C begins to dissolve, and the dissolution rate is slower than that of M6C. At 1280°C, in austenite: C 0.5%, W 7-8%, Cr 4%,...
Heat Treatment Forging and Annealing of High Speed Steel
1. Forging Due to the high carbon content of steel and a large amount of alloying elements, the as-cast billet structure has fish bone carbides. It can only be broken by forging and evenly distributed. 2. Annealing After high-speed steel is forged and rolled, the steel needs to be annealed. Elimi...
The Role of Chemical Elements in High-speed Tool Steel
1. C: Mechanism: K formation, solid solution strengthening. Carbon has a great influence on the hardness of high-speed steel and is the main strengthening element; C% increased, HRC and hot hardness increased after quenching and tempering. Disadvantages: The increase of carbon content increases t...
vacuum Brazing Process Method, Quality Problems and Solutions of Woodworking Tool Carbide and Steel
1. Preparing woodworking tools for welding (1) Check whether the cemented carbide is defective before welding. The welding surface must meet the technical requirements of the drawing and ensure that there is a parallel gap between the alloy and the substrate, so that the welding quality can be ea...
Heat Treatment of Tools and Dies
In mold manufacturing, mold material is the basis of its progress, and molds include plastic mold steel, hot work mold steel and cold work mold steel. 1. Commonly Used Mold Materials (1) High-speed steel Due to its higher toughness and thermoplasticity, molybdenum-based high-speed steel can be u...
