SK85 JIS High Carbon Tool Steel

SK85 is known for its excellent wear resistance, hardness, and toughness. It has a carbon content of 0.80% - 0.90%, which makes it one of the hardest tool steels available. It also contains small amounts of other alloying elements, such as silicon, manganese, and chromium, which contribute to its strength and durability.

This steel is often used in applications that require high precision and accuracy, such as in the medical or aerospace industry. It is also commonly used in the manufacture of springs, gears, and other mechanical components that require high strength and wear resistance.

In terms of heat treatment, SK85 can be hardened and tempered to achieve a range of different properties, depending on the specific application. It is important to follow the proper heat treatment procedures to ensure that the steel has the desired properties for the intended use.

Polish high carbon steel strip, good flatness and straightness, make band saw blade cut smoothly and quickly and more durable.

3. Bearings: SK85JIS high carbon tool steel is also commonly used for bearings in high-stress environments due to its high resistance to wear and deformation.

4. Automotive parts: SK85JIS high carbon 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.

5. Tooling: SK85JIS high carbon 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.

6. Construction: SK85JIS high carbon 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.

SK85 JIS high carbon tool steel can be surface treated in several ways to improve its properties and performance. Here are some common surface treatments used for SK85 JIS high carbon tool steel:

1. Heat treatment: SK85 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.

2. 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.

3. Coating: SK85 can be coated with materials such as titanium nitride, chromium, or tungsten carbide to increase its wear resistance and hardness.

4. 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.

5. 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.
