About products
8CR3 is a type of high-carbon steel with a chromium content of 8%. It also contains a small
amount of tungsten, vanadium, and molybdenum. This composition gives it a high hardness,
wear resistance, and edge retention. 8CR3 steel is ideal for making knives, cutting tools, and
other industrial applications requiring highly durable and resistant steel.

8CR3 Steel Uses
Due to its excellent properties, 8CR3 steel is used in many applications. It is commonly used
to produce cutting tools, knives, surgical equipment, and industrial machinery components. It also
manufactures ball bearings, die-casting dies, and mould inserts.
8CR3 Steel Hardness
8CR3 steel is known for its high hardness level. Its Rockwell hardness rating ranges between 58-62,
which is higher than most other types of steel. This makes it extremely durable and wear-resistant,
ideal for cutting tools and knives.
8CR3 Steel Heat Treatment
Heat treatment is an essential process in the production of 8CR3 steel. It is usually subjected to a
quenching and tempering process to achieve the desired hardness and toughness. The steel is
heated to high temperatures, quenched rapidly in oil or water to harden the steel, and then tempered
to reduce brittleness and improve toughness.
Conclusion:
In summary, 8CR3 steel is a type of high-carbon steel with excellent wear resistance, hardness,
and edge retention. Its unique properties make it ideal for various industrial applications, including
cutting tools, knives, and moulding inserts. However, it is more brittle than other steel types and must
be treated carefully during quenching and tempering to prevent cracking. If you want highly durable
and resistant steel, 8CR3 steel is an excellent choice.
