C45 plates type of medium carbon steel plate known for its excellent mechanical properties and versatility in industrial applications. This grade of steel, also known as EN 10083-2, offers good tensile strength, toughness, and wear resistance. It can be heat treated to achieve various hardness levels, making it suitable for applications that require strong, durable components.
C45 plates are commonly used in manufacturing machinery parts, automotive components, and industrial tools where reliable performance under stress and wear is crucial. These plates are often supplied in untreated or normalized conditions and can be further hardened through processes like quenching and tempering or induction hardening.
Amardeep Steel is a leading supplier known for high-quality C45 plates, which are widely appreciated for their superior features. C45 is a versatile grade of steel capable of through hardening via quenching and tempering on limited sections, and it can also be flame or induction hardened to achieve hardness up to HRC 55. C45 comes in various variations denoted by additional letters, which offer slight modifications in chemical composition.
