High speed steel is a type of tool steel with high hardness, wear resistance, and heat resistance, also known as high-speed tool steel or sharp steel, commonly known as white steel. High speed steel is the F. of the United States W. Taylor and M White created it in 1898.
High speed steel has good processability and a good combination of strength and toughness, so it is mainly used to manufacture complex thin edged and impact resistant metal cutting tools, as well as high-temperature bearings and cold extrusion molds. In addition to high-speed steel produced by smelting methods, powder metallurgy high-speed steel has emerged since the 1960s. Its advantage is that it avoids the mechanical property degradation and heat treatment deformation caused by carbide segregation in smelting production.
Specifications and appearance
The specifications mainly include round steel, square steel, and sheet metal. The surface of steel should be well processed and free from visible cracks, folds, scars, and hairlines. The surface of cold drawn steel should be clean, smooth, free of inclusions and oxide scales.
Main types
High speed steel is a complex type of steel with a carbon content generally ranging from 0.70% to 1.65%. The content of alloying elements is relatively high, and the total amount can reach 10-25%. According to the different alloy elements contained, it can be divided into: ① tungsten based high-speed steel (containing 9-18% tungsten); ② Tungsten molybdenum high-speed steel (containing 5-12% tungsten and 2-6% molybdenum); ③ High molybdenum high-speed steel (containing 0-2% tungsten and 5-10% molybdenum); ④ Vanadium high-speed steel is divided into general vanadium content (1-2% vanadium content) and high vanadium content (2.5-5% vanadium content) high-speed steel according to different vanadium contents; ⑤ Cobalt high-speed steel (containing 5-10% cobalt). High speed steel can be divided into two types according to their different uses: general-purpose and special-purpose Universal high-speed steel: mainly used for manufacturing cutting tools (such as drill bits, taps, saw blades) and precision tools (such as rolling cutters, hobbing cutters, and pulling cutters) for metal materials with cutting hardness HB ≤ 300. Commonly used steel grades include W18Cr4V, W6Mo5Cr4V2, etc Special purpose high-speed steel: including cobalt high-speed steel and superhard high-speed steel (hardness HRC68-70), mainly used for manufacturing cutting tools for difficult to machine metals such as high-temperature alloys, titanium alloys, and high-strength steel. Commonly used steel grades include W12Cr4V5Co5, W2Mo9Cr4VCo8, etc.
