Applications of Tool Steel

Blades

Due to its high hardness and wear resistance, tool steel is commonly used for blades in cutting tools such as knives, saw blades, and scissors.

Springs

Tool steel has excellent spring properties, which make it a popular choice for use in springs that require high strength and durability.

Bearings

Tool steel is also commonly used for bearings in high-stress environments due to its high resistance to wear and deformation.

Automotive parts

Tool steel is frequently used in the manufacture of automotive parts such as crankshafts, camshafts, and valve springs due to its high strength and toughness.

Tooling

Tool steel is often used in the manufacture of tooling and dies used in the production of various items such as automotive parts, electronic components, and household appliances.

Construction

Tool steel is a popular choice for use in construction due to its high strength and durability, making it ideal for items such as concrete reinforcing bars and bridge cables.

Surface Treatment Of Tool Steel

Heat Treatment

Tool steel can be heated to achieve different levels of hardness and strength. Heat treatment includes annealing, normalizing, quenching, and tempering. Annealing softens the steel and makes it more malleable, normalizing improves its strength and ductility, quenching hardens the steel, and tempering improves its toughness.

Nitriding

Nitriding is a surface hardening treatment that involves the diffusion of nitrogen into the surface of the steel. This process results in a hard, wear-resistant surface that is resistant to corrosion.

Coating

Tool steel can be coated with materials such as titanium nitride, chromium, or tungsten carbide to increase its wear resistance and hardness.

Shot Peening

Shot peening is a surface treatment that involves bombarding the steel with small particles to improve its fatigue strength, resistance to cracking, and overall toughness.

Electroplating

Electroplating is a process where a layer of metal is deposited onto the surface of the steel to improve its properties. Common electroplating materials include zinc, tin, and nickel.

Packaging and Shipping of Tool Steel

Packing	Sleeved into plastic bag individually, pieces wrapped with water-proof material, bundled with nylon rope
Shipping	Shipped by road, sea, rail or air

FAQ

Q: Is tool steel stronger than steel?

A: In general, mild steel is more ductile and less expensive, making it suitable for structural and general manufacturing applications. Due to its greater hardness and strength, tool steel is more suitable for specialised applications under high stress.

Q: Which steel is best for tools?

A: M2 tool steel is the most commonly used grade of the high speed category. It is a molybdenum tungsten grade with excellent toughness, wear resistance and red hardness, making it preferable in applications where it is exposed to high heat condition from high machining speeds.

Q: Is tool steel stronger than titanium?

A: One area where steel is clearly superior is hardness. Steel has a greater overall hardness, especially its carbon content. Titanium alloys typically have a Rockwell C rating of less than 40, while steel can easily surpass this figure depending on the type. However, there are exceptions.

Q: What are the 6 grades of tool steel?

A: There are six groups of tool steels: water-hardening, cold-work, shock-resistant, high-speed, hot-work, and special purpose.

Q: What is AISI 01 tool steel equivalent to?

A: AISI O1 is equivalent of DIN 2510 Tool Steel is the oil-hardening, “non-shrinking” tool steel, good cutting edge retention; high harden ability and dimensional stability during heat treatment.

Q: Does tool steel need to be hardened?

A: These steels must be heat treated to develop their characteristic properties. The heat treating process alters the alloy distribution and transforms the soft matrix into a hard matrix capable of withstanding the pressure, abrasion and impacts inherent in metal forming.

Q: Why can't you weld hardened steel?

A: Work- or strain-hardened metals exposed to the intense localized head of welding tend to recrystallize and soften in the heat-affected zone (HAZ). Assuming the correct filler metal is used, the only area affected is the HAZ.
