M2 High Speed Steel (HSS) is a type of tool steel that is widely used in the manufacturing industry for making cutting tools and other metal-working tools. It is a molybdenum-type high-speed steel which has substantial tungsten quantity. The high molybdenum content of M2 HSS makes it suitable for use in high-speed cutting applications, such as drilling, milling, and turning.
One of the key features of M2 HSS is its high toughness, which makes it resistant to breakage and chipping and this quality makes it ideal material for applications that require high cutting speeds, and applications where the tool needs to withstand high temperatures and extreme pressure. M2 HSS has good wear resistance and high hardness, making it a popular choice for manufacturing tools that are subjected to heavy use and wear.
M2 HSS is typically supplied in the form of a flat bar, which is a rectangular-shaped piece of steel that is flat on both sides. Any M2 Steel supplier can guide you about what size of bars are available with them. Flat bars are often used in the manufacturing of tools, as well as in the construction of structures and other metal products. They are available in a variety of thicknesses and widths, and can be machined and shaped to meet the specific requirements of the application.
One of the benefits of using M2 HSS flat bars is their ability to withstand high temperatures without losing their strength or hardness. This makes them ideal for use in high-speed cutting applications, where the tool must maintain its cutting ability even when subjected to high temperatures generated by the cutting process. The high molybdenum content of M2 HSS also provides good resistance to heat checking, which is the formation of cracks or chips on the surface of the tool caused by exposure to high temperatures.
Another benefit of M2 HSS flat bars is their ability to maintain their cutting ability even when subjected to repeated use and wear. This is due to the high hardness and wear resistance of M2 HSS, which allows the tool to maintain its cutting edge even after extended use. In addition, M2 HSS flat bars are resistant to corrosion and staining, making them suitable for use in a variety of environments, including wet and humid conditions.
The manufacturing process for M2 HSS flat bars involves melting the steel to its liquid form, and then casting it into the desired shape. After casting, the steel is heat treated to achieve the desired hardness and toughness. The heat treatment process typically involves heating the steel to a high temperature and then cooling it rapidly to a lower temperature, which helps to achieve the desired properties of the steel.
In terms of applications, M2 HSS flat bars are commonly used in the manufacturing of cutting tools, such as drills, reamers, taps, and end mills. They are also used for the manufacture of punches, dies, and other metal-working tools. M2 HSS flat bars are also used in the construction of structures, such as bridges, buildings, and machinery components, because of their strength and durability.
When it comes to machining M2 HSS flat bars, it is important to use high-speed cutting tools, such as carbide or ceramic tools. It is also important to use a coolant when cutting M2 HSS, as this will help to reduce heat build-up and prevent damage to the tool.
M2 High Speed Steel (HSS) flat bars are a versatile and high-performing type of tool steel.
