Key Features of High Speed Steel (HSS)
Excellent Red Hardness: It can maintain high hardness at high temperatures up to 500-600°C, suitable for high-speed cutting.
Excellent Wear Resistance： Alloy elements such as tungsten, molybdenum, and vanadium significantly improve wear resistance and prolong tool life.
Good Toughness: It is more impact-resistant than cemented carbide and suitable for intermittent cutting or heavy-duty processing.
Excellent Machinability: It is easy to grind, regrind, and reprocess, and it is easy to reuse.
Variety of Grades: Including M2, M35, M42, W18Cr4V, etc., which can be selected according to the purpose.
With heat treatment control performance (Heat Treatability) : Adjust hardness, toughness, and other properties through quenching and tempering to achieve performance customization.
Good Dimensional Stability: Small deformation after heat treatment, suitable for manufacturing high-precision tools and parts.

FAQs about HSS
What is the difference between M2 and M42 High Speed Steel?
M2 is a general-purpose HSS with good toughness and wear resistance. M42 contains 8% cobalt, giving it better red hardness and cutting performance for harder materials.
What is High Speed Steel?
High Speed Steel (HSS) is a category of tool steel known for its ability to retain hardness at elevated temperatures. It is used extensively in cutting tools like drills, taps, saw blades, and milling cutters because it allows tools to cut faster without losing strength or shape. HSS combines wear resistance, toughness, and heat resistance, making it ideal for high-speed machining.
Can You Weld High Speed Steel?
Yes, High Speed Steel can be welded, but with caution. Due to its high carbon and alloy content, HSS is prone to cracking and distortion if not properly preheated and cooled. Welding should be performed using:
Preheating (200–400°C)
Low hydrogen welding rods
Post-weld stress relief or annealing
For critical tooling applications, brazing or mechanical fastening is often preferred over welding.
How Hard is High Speed Steel?
High Speed Steel is extremely hard. After heat treatment, HSS typically reaches:
Rockwell Hardness (HRC): 62–70 HRC
This high level of hardness allows HSS tools to maintain a sharp edge and resist wear even under intense pressure and temperature during high-speed machining.
Can HSS be customized for specific tool applications?
Yes, Huaxiao Metal provides custom-cut High Speed Steel in various forms to meet your specific tooling and machining needs.
What is the Difference Between HSS and Carbide?
| Feature | High Speed Steel (HSS) | Carbide |
|---|---|---|
| Toughness | High | Lower (more brittle) |
| Hardness | Moderate to High (62–70 HRC) | Very High (~90 HRA) |
| Cost | Lower | Higher |
| Sharpening | Easier | Harder to regrind |
| Use Case | General machining, rigid materials | High-speed, high-volume cutting |
HSS is preferred for more demanding jobs and interrupted cuts, while carbide excels in high-speed precision cutting.
Is High Speed Steel Magnetic?
Can High Speed Steel Rust?
Yes. While HSS contains elements like chromium and molybdenum that offer some corrosion resistance, it is not stainless steel and can rust under humid or corrosive conditions. To prevent rust:
Store tools in a dry place
Use protective coatings or oils
Clean after use, especially in wet or chemical environments
Do you export HSS internationally?
Absolutely. We have extensive export experience and ship to over 50 countries worldwide with proper documentation and packaging.
