High-Speed Tool Steels: Grades, Properties, Applications, and Pricing

Introduction to High Speed Tool Steels

High speed tool steels (HSS) are a category of tool steels designed for cutting, machining, and industrial applications where high hardness, wear resistance, and heat resistance are required.

These steels maintain their hardness even at high temperatures, a property known as red hardness or hot hardness.

This makes them the preferred material for cutting tools, drills, taps, milling cutters, and industrial machine components.

Milano Special Steel, a leading supplier based in Gurugram, Haryana, specializes in supplying high-speed tool steels M2, M35, M42, M50, and M52 in plate and round bar form.

We supply wholesale, retail, and cut-piece sizes to meet customer requirements across India.

Our high-speed tool steels serve major industries such as:

• Sheet metal cutting
• Cutting tools manufacturing
• Plastic molds making
• Automotive industry
• Forging industry
• Industrial machines
• Defense industry parts manufacturing

What is High Speed Tool Steel?

High speed steel (HSS) is a type of alloy tool steel known for its ability to cut materials at high speeds while maintaining hardness and wear resistance.

Unlike carbon steels, which lose hardness at high temperatures, HSS retains its cutting edge even when exposed to extreme heat.

Key Properties of High-Speed Tool Steels:

✔ High Hardness & Strength – Provides excellent wear resistance and durability.
✔ Hot Hardness (Red Hardness) – Retains hardness even at temperatures up to 1100°F (593°C).
✔ Superior Toughness – Resists chipping and cracking under heavy loads.
✔ Excellent Wear Resistance – Ensures longer tool life and consistent performance.
✔ Good Machinability – Can be ground and machined to precise dimensions.

High Speed Tool Steel Grades We Supply

1. M2 High Speed Tool Steel

M2 steel is the most commonly used high-speed steel grade, offering a balance of hardness, toughness, and wear resistance.

It is widely used in drills, taps, milling cutters, and industrial cutting tools.

✔ Chemical Composition of M2 Steel:

• Carbon (C): 0.85-0.95%
• Tungsten (W): 5.50-6.75%
• Molybdenum (Mo): 4.50-5.50%
• Vanadium (V): 1.75-2.20%
• Chromium (Cr): 3.75-4.50%

✔ Applications of M2 Steel:

• Twist drills, taps, reamers
• Milling cutters, broaches, and end mills
• Industrial knives and cutting tools

2. M35 High Speed Tool Steel

M35 steel is a cobalt-bearing high-speed steel that offers superior hot hardness and wear resistance compared to M2.

It is ideal for applications requiring prolonged exposure to high temperatures and extreme cutting conditions.

✔ Chemical Composition of M35 Steel:

• Carbon (C): 0.90-1.00%
• Cobalt (Co): 4.50-5.00%
• Molybdenum (Mo): 4.50-5.50%
• Chromium (Cr): 3.75-4.50%
• Tungsten (W): 5.50-6.75%
• Vanadium (V): 1.75-2.20%

✔ Applications of M35 Steel:

• High-performance drills and cutting tools
• Gear-cutting tools and saw blades
• Plastic mold inserts and extrusion dies

3. M42 High-Speed Tool Steel

M42 steel is a super high-speed steel containing 8% cobalt, providing exceptional hot hardness and wear resistance.

It is ideal for high-performance machining operations and heavy-duty cutting tools.

✔ Chemical Composition of M42 Steel:

• Carbon (C): 1.05-1.15%
• Cobalt (Co): 7.75-8.75%
• Chromium (Cr): 3.50-4.25%
• Molybdenum (Mo): 9.00-10.00%
• Vanadium (V): 0.90-1.20%

✔ Applications of M42 Steel:

• High-performance saw blades
• Aerospace and automotive cutting tools
• Punching and stamping dies

4. M50 & M52 High-Speed Tool Steels

M50 and M52 steels are classified as intermediate high-speed steels, offering a balance of toughness and wear resistance.

These grades are used in high-precision bearings, gears, and industrial machine components.

✔ Applications of M50 & M52 Steel:

• Aerospace bearings and shafts
• Precision cutting tools
• High-speed industrial machine components
