Introduction to Tool Steel
Tool steel is a category of carbon and alloy steels specifically engineered to create tools such as hand tools due to its ability to withstand high temperatures and high wear resistance. Renowned for their exceptional hardness and toughness, tool steels are integral to various industrial applications.
These steels include high carbon steel and other alloy steels with a carbon content between 0.5% and 1.5%. They also contain elements like chromium, which enhance their performance and durability.
Different types of tool steel, such as water-hardening, cold-work, high-speed steels, etc., are made to meet specific operational needs. Tool steel is essential in manufacturing and is used for cutting, shaping, and forming materials with precision and durability.
Benefits of Tool Steel
The benefits of Tool Steel include:
- Great for cutting and shaping
- Long-lasting and durable
- Less frequent replacements
- Stays hard at high temperatures
- Used in hand tools, cutting tools, and dies
- More resistant to rust and wear
- Options like high carbon and alloy steel for different needs
Types & Grades of Tool Steel
Tool steels are commonly categorized into:
- Water Hardening Tool Steel (W-Grade)
- Cold Work Tool Steel (O-Grade/A-Grade/D-Grade)

What steel is considered tool steel?
Tool steels are carbon and alloy steels known for their high hardness, resistance to abrasion, and ability to retain a sharp cutting edge. They are specifically designed for manufacturing tools like cutting, shaping, and forming tools.
Is 4140 a tool steel?
No, 4140 is a low-alloy steel known for its excellent toughness, strength, and wear resistance, but it is primarily used in applications like gears, shafts, and structural components, not typically classified as a tool steel.
What is the best steel for tool making?
High-speed steels (HSS), such as M2, and D2 tool steel are among the best for tool making. HSS is known for its ability to cut at high speeds while maintaining its hardness and edge. D2 tool steel is renowned for its high wear resistance and toughness.
Is A36 a tool steel?
No, A36 is a mild carbon steel primarily used in structural applications like building construction and bridges. It lacks the hardness and wear resistance necessary for tool steel applications.
Is high-speed steel a tool steel?
Yes, high-speed steel (HSS) is a type of tool steel known for its ability to withstand high temperatures without losing hardness, making it ideal for high-speed cutting tools.
