Grade M2/ 1.3343
Grade M2, also known as 1.3343, is a premium high-speed steel (HSS) widely used in cutting, drilling, milling, and high-speed machining applications. It is engineered to deliver an optimal combination of hardness, wear resistance, toughness, and red-hardness, making it one of the most versatile tool steels in the industry.
M2 HSS is capable of maintaining its hardness even at elevated temperatures up to 600°C, allowing tools to operate efficiently at high cutting speeds without losing sharpness. This makes it highly suitable for continuous machining operations and precision tool manufacturing.
The presence of carbide-forming elements such as tungsten, molybdenum, and vanadium enhances wear resistance and tool life. At the same time, the steel retains sufficient toughness to resist chipping and breakage under heavy cutting loads.
Due to its reliability and performance, M2 is widely used across metalworking, automotive, and manufacturing industries for producing high-performance cutting tools and precision components.
