High-Speed Steel (HSS) is a type of tool steel with high hardness, high wear resistance, and high heat resistance. Also known as high-speed tool steel or sharp steel, it is commonly referred to as "white steel" in daily use.

Detailed parameters of High-Speed Steel:

1.Hardness: HSS boasts extremely high hardness. It can maintain high hardness even under the high heat generated by high-speed cutting (approximately 500℃), with an HRC value typically exceeding 60.

2.Density: The density of HSS ranges from approximately 8.3 to 8.7 g/cm³.

3.Alloying Elements: HSS is a complex alloy steel containing carbide-forming elements such as tungsten (W), molybdenum (Mo), chromium (Cr), cobalt (Co), and vanadium (V). The total content of these elements is usually between 10% and 25%.

4.Red Hardness: HSS exhibits excellent red hardness, meaning it can retain hardness and wear resistance at high temperatures. This is one of its most prominent characteristics.

5.Manufacturing & Applications: Thanks to its good processability combined with strength and toughness, HSS is mainly used for manufacturing complex, thin-edged, and impact-resistant metal cutting tools. It is also applied in the production of high-temperature bearings and cold extrusion dies, among other products.
