1. Charateristics
C45 is a medium carbon steel grade offering reasonable tensile strength. Supplied in the cold drawn or hot rolled condition, tensile properties can vary but are approximately between 500-800 N/mm². This grade can be flame or induction hardened to produce a good surface hardness with moderate wear resistance. C45 is widely used for components that require better properties than mild steel but does not justify the costs of an alloy steel.
2. Applications
C45 is widely used for many general engineering applications. Typical applications include tools, shafts, nuts, bolts, connecting rods, screws, rollers.
