What are carbon steels used for?
Carbon steel can be classified into three categories according to its carbon content: low-carbon steel (or mild-carbon steel), medium-carbon steel and high-carbon steel [1]. Their carbon content, microstructure and properties compare as follows:
Carbon content (wt.%) | Microstructure | Properties | Examples | |
---|---|---|---|---|
Low-carbon steel | < 0.25 | Ferrite, pearlite | Low hardness and cost. High ductility, toughness, machinability and weldability | AISI 304, ASTM A815, AISI 316L |
Medium-carbon steel | 0.25 – 0.60 | Martensite | Low hardenability, medium strength, ductility and toughness | AISI 409, ASTM A29, SCM435 |
High-carbon steel | 0.60 – 1.25 | Pearlite | High hardness, strength, low ductility | AISI 440C, EN 10088-3 |
