When it comes to composition, C45 carbon steel has about 0.42–0.50% carbon and 0.50–0.80% manganese, along with minimal amounts of silicon, phosphorus, and sulfur. This blend gives it a higher hardness and tensile strength compared to lower carbon steels. You can expect a tensile strength ranging from 570–700 MPa and a yield strength of about 330 MPa in its normalized state. With the right heat treatment, it can reach even better mechanical properties, enhancing surface hardness and fatigue strength. C45 steel is also known for its good machinability, especially when annealed, and it handles processes like flame cutting, welding (with some care), forging, and induction hardening quite well.
Carbon Steel C45 is a medium carbon steel that stands out for its impressive strength, good machinability, and remarkable wear resistance. It’s the go-to choice when you need something stronger and harder than mild steel, but still want to keep that all-important toughness. Typically, you’ll find it in a normalized or hot-rolled state, and it can also be heat-treated through hardening and tempering. This steel is a favorite in engineering and industrial fields for parts that strike a balance between performance and cost. Its versatility and widespread availability make it a top pick for manufacturers and fabricators around the globe.
