SK3 High-carbon Steel

 

SK3 steel is a high-quality carbon tool steel with the following specific information:

Standard: The main standards for SK3 steel are the Japanese standard JIS G4401 and the Chinese standard GB/T1298.

 

Chemical composition: The chemical composition of SK3 steel includes carbon (C) ranging from 0.80-0.90%, silicon (Si) ranging from 0.10-0.35%, manganese (Mn) ranging from 0.10-0.50%, and the content of phosphorus (P) and sulfur (S) does not exceed 0.030%.

 

Properties: SK3 steel has a tensile strength of 570-880 MPa, a yield strength of 320 MPa, and a fracture elongation of 14%.

 

Uses: SK3 steel is primarily used for manufacturing cold stamping molds, cutting tools, springs, and other components that require high hardness and wear resistance.

 

Condition: SK3 steel is usually supplied in an annealed state, which has relatively low hardness and good machinability.

 

Advantages: SK3 steel has good hardenability, allowing it to achieve high hardness and wear resistance. It also has good adjustability and machinability.

 

Disadvantages: SK3 steel has relatively poor toughness and is prone to fractures. Care should be taken to prevent excessive deformation and fracture during use.

 

Common forms: Common forms of SK3 steel include round bars, flat bars, and sheets.

 

Comparison of national standards: Compared to carbon tool steel grades in other countries, the chemical composition and properties of SK3 steel are slightly different. In China, a similar grade is T10 steel, following the GB/T1298 standard.

 

In summary, SK3 steel is a high-hardness and wear-resistant carbon tool steel, mainly used for manufacturing cold stamping molds, cutting tools, springs, and mechanical components. Understanding its standards, chemical composition, properties, uses, condition, advantages, disadvantages, and common forms helps in selecting and applying this steel material.
