High Speed Steel

High Speed Steel (HSS) is a high-performance tool steel widely used for manufacturing cutting tools and machining components that require excellent hardness, wear resistance and dependable performance. At IMI Special Steels & Alloys, we offer a comprehensive range of High Speed Steel grades suitable for diverse industrial and engineering applications. High Speed Steel is designed to perform effectively in demanding machining environments and is commonly selected for applications involving drilling, tapping, milling, turning, broaching and sawing.

Our High Speed Steel range includes popular and widely used grades such as M2 (1.3343), M35 (1.3243), M42 (1.3247), T1 (1.3355), T15 (1.3202), T42 (1.3245) and M7 (1.3348). These grades are available to support different tooling and machining requirements. Selecting the appropriate High Speed Steel grade can help manufacturers achieve the required balance of hardness, wear resistance, toughness and performance for their specific applications.

High Speed Steel is known for its high hardness, typically achieving approximately RC 62–65 after appropriate heat treatment. This high level of hardness makes HSS suitable for demanding cutting and machining applications where tools are exposed to continuous friction and wear. The material also offers high wear resistance, helping tools maintain their working performance during demanding operations. Its ability to be heat-treated to achieve high hardness and wear resistance is one of the important characteristics that makes High Speed Steel a preferred material for industrial cutting tools.

In addition to hardness and wear resistance, High Speed Steel offers good toughness and impact resistance. This combination is important for tooling applications where the material may experience mechanical stress during operation. HSS is also valued for its resistance to deformation and cracking, helping support dependable performance in demanding machining environments. The combination of hardness, toughness and wear resistance makes High Speed Steel suitable for a broad range of cutting and forming applications.

M2 (1.3343) is one of the High Speed Steel grades included in our product range and is widely used for general-purpose cutting tools and machining applications. M35 (1.3243) and M42 (1.3247) are also available for applications requiring high-performance tooling solutions. Our range further includes T1 (1.3355), T15 (1.3202), T42 (1.3245) and M7 (1.3348), providing customers with multiple High Speed Steel options for different industrial and engineering requirements.

High Speed Steel is extensively used in the manufacturing of drilling, tapping and machining tools. The material's high hardness and wear resistance make it suitable for tools that need to maintain their cutting performance during repeated operations. HSS is also used for broaching and form tools, where dependable material performance is important for achieving the required machining results. The ability of High Speed Steel to withstand demanding working conditions makes it a valuable material choice for many precision tooling applications.

Another important application of High Speed Steel is in high-speed machining and turning tools. Tools used in machining operations are often required to work under conditions involving friction, mechanical stress and continuous contact with the workpiece. The properties of HSS help support cutting performance and accuracy in these applications. High Speed Steel is also commonly used for manufacturing milling and sawing tools, making it suitable for a wide range of industrial machining operations.

High Speed Steel can also be used for machining demanding materials, including hard materials such as titanium and stainless steel. Selecting the appropriate HSS grade for the specific machining application is important to achieving suitable performance. With multiple grades available, manufacturers and engineering professionals can choose High Speed Steel materials based on their tooling requirements and application needs.

One of the key benefits of using High Speed Steel is increased tool life due to its high wear resistance. Tools manufactured using suitable HSS grades can offer dependable resistance to wear during demanding operations, which can help reduce the frequency of tool replacement. This contributes to another important benefit—reduced tool replacement costs. By selecting a suitable material for the application, businesses can improve operational efficiency and manage tooling requirements more effectively.

Improved cutting performance and accuracy are additional benefits associated with High Speed Steel applications. The material's combination of high hardness, wear resistance and toughness supports its use in precision cutting and machining tools. High Speed Steel is also suitable for machining carbon steels and alloy steels, making it a versatile material for a variety of manufacturing and engineering operations.
