High Speed Tool Steel

High speed tool making steel or high cycle tool steel is referred to as HSS for short. It is a type of tool-making steel that is characterized by its ability to cut materials at high speeds. It contains a complex chemical mixture that balances hardness, toughness, and high temperature resistance. Here are some of the types of high-speed tool steels according to DIN standards, along with their features and application benefits.

1. DIN1.3343 (M2) this is a molybdenum-based HSS, which is widely used. It has excellent wear resistance and toughness. This makes it suitable for many types of cutting tools, such as drills, taps, and end mills. Leong Jin has this grade in stock to serve.
2. DIN1.3243 (M35) M35 is similar to M2, but with the addition of cobalt, which increases heat resistance.
3. DIN 1.3247 (M42) M42 is a cobalt-based HSS with a high cobalt content, which provides superior hardness and heat resistance.
4. DIN 1.3348 (M52) M52 is a high alloy HSS with excellent hot hardness retention ability and wear resistance. It is used for high-performance cutting tools that require high cutting speeds.
5. DIN 1.3207 (S10-4-3-10) this grade has a high tungsten content and has exceptional hardness and abrasion resistance. It is suitable for heavy cutting work.

Each steel grade has been developed to meet specific requirements in terms of cutting speed. The choice of HSS will depend on the specific application and the performance requirements of the cutting tool. High-speed tool steels are important in modern manufacturing due to their ability to maintain cutting edges at high temperatures. This results in faster machining times and longer tool life.
