Application:HSS has tungsten, molybdenum, chromium, vanadium and other alloying elements, with a white metallic luster.

Hardness after Heat-treated :HRC63-70.

With good toughness and strength and good workmanship, can withstand greater impact, easy to sharpen to get a sharp edge, but poor heat resistance, can only withstand a temperature of 600 ℃, so can not be used with high-speed Cutting.

HSS is particularly suitable for the manufacture of a variety of complex structure of the shape of the turning tool, threaded tools, drills, reamers and so on. High-speed steel can be used for milling, planing, drilling and other cutting processes, usually used to cut a variety of hardness of metal materials, such as cast iron, carbon steel, alloy steel, stainless steel, aluminium alloy, etc.

HSS turning tool has the advantages of high-precision machining, high service life, but the cost is relatively high, and there is a large vibration and noise. Therefore, the choice of turning tools should be based on the processing of the material, the requirements of the workpiece and the use of equipment and other factors for comprehensive consideration.
