How is carbon steel classified? What are the classifications of carbon steel? The classification of carbon steel is mainly based on carbon content, quality and use.
1. Classification by carbon content:
Low carbon steel: Carbon steel with a carbon content of less than 0.25%, with good plasticity and toughness, but low strength, is usually used to manufacture parts that do not require high strength but require good plasticity and toughness, such as bridges, building components, etc.
Medium carbon steel: Carbon content is between 0.25% and 0.6%, with good strength and toughness, used to manufacture parts that require certain strength and toughness, such as automotive parts, mechanical parts, etc.
High carbon steel: Carbon steel with a carbon content higher than 0.6%, with high hardness and strength, but poor plasticity and toughness, is mainly used to manufacture tools and parts that require high hardness and wear resistance, such as knives, molds, etc.
2. Classification by quality:
Ordinary quality carbon steel: Carbon content is less than 0.05%, mainly used for general engineering components and mechanical parts.
High-quality carbon steel: The carbon content is less than 0.8%. Its mechanical properties are significantly improved after heat treatment. It is often used to manufacture important mechanical parts.
Advanced high-quality carbon steel: It contains lower carbon content and very few impurities. It is used to manufacture parts that require extremely high mechanical properties.
3.Classification by use:
Carbon structural steel: Mainly used to manufacture various engineering components, bridges, building components and machine parts.
Carbon Tool Steel: Mainly used to manufacture various cutting tools, measuring tools, molds, etc., which require high hardness and wear resistance.
To sum up, carbon steel is classified according to its carbon content, quality and usage to meet different industrial needs.
