To distinguish between hard alloy and high-speed steel (HSS):
1.Composition:
High-speed steel is an alloy steel with elements like tungsten, molybdenum, chromium, vanadium, and cobalt, enhancing its hardness and wear resistance.
Hard alloy, also known as cemented carbide, is a composite material primarily composed of tungsten carbide particles bonded together by a metallic binder, often cobalt .
2.Properties:
HSS is renowned for its ability to withstand high temperatures and maintain its cutting edge, making it suitable for high-speed machining applications.
Hard alloy exhibits exceptional hardness, wear resistance, and toughness, making it ideal for cutting tools, drills, and other abrasive applications .
3.Application:
High-speed steel is commonly used for cutting tools in metalworking, woodworking, and plastic machining due to its ability to maintain cutting performance at high speeds and temperatures.
Hard alloy is preferred for machining operations where high hardness and wear resistance are required, such as drilling, milling, and turning of hard materials like steel, cast iron, and stainless steel .
4.Testing:
Spark testing can help determine the type of steel based on spark characteristics, but factors like hardness and grinding wheel type also play a role .
By considering their composition, properties, applications, and testing methods, one can effectively distinguish between hard alloy and high-speed steel.
