Steel product indicators

1. Chemical composition: The chemical composition of steel has an important impact on its performance. Common chemical components include carbon (C), sulfur (S), phosphorus (P), manganese (Mn), silicon (Si), chromium (Cr), nickel (Ni) and other elements. The content of these elements needs to be controlled within a certain range to ensure the performance and quality of steel.
2. Mechanical properties: Also called mechanical properties, this is one of the important indicators of steel quality. Key indicators include:
• Strength: refers to the ability of a material to resist deformation or breakage. Measures of strength include yield strength and tensile strength. Yield strength is the basis for determining the strength of steel in structural design, while tensile strength reflects the maximum force that steel can withstand during stretching.
• Hardness: refers to the ability of a material surface to resist the intrusion of hard objects. Common hardness indicators include Brinell hardness, Rockwell hardness and Vickers hardness. The higher the hardness, the better the wear resistance of the steel.
• Plasticity: refers to the ability of a material to deform without breaking. Plasticity indicators such as elongation and reduction of area are used to measure the formability of steel. The higher the plasticity, the better the ductility of the steel.
• Toughness: Also called impact toughness, it refers to the ability of a material to resist impact deformation. Toughness is a measure of the impact resistance of steel. The higher the value, the stronger the steel's ability to resist movement loads.
3. Physical properties: This includes the density, thermal expansion coefficient, thermal conductivity, electrical conductivity, etc. of steel. These properties have an important impact on the application of steel in various environmental conditions.
4. Process performance: mainly measures the performance of steel during processing, such as weldability, cutting processability, etc.
