C45 cold-rolled steel plate is a high-quality carbon structural steel with good mechanical properties and processing properties. C45 cold-rolled steel plates are commonly used to manufacture mechanical parts, automotive parts, aerospace parts, etc.
High strength: It has high tensile strength and yield strength and can withstand larger loads.Good processing performance: Cold-rolled steel plates have uniform thickness, high surface finish, and are easy to process. They can be processed by stamping, cutting, welding and other processing methods.Good corrosion resistance: The galvanized layer formed on the surface of the cold-rolled steel plate can provide good corrosion resistance and extend the service life of the steel plate.Easy to transport and store: Cold-rolled steel sheets are relatively thin and lightweight, making them easy to transport and store, reducing transportation costs and storage space requirements.Recyclable: Cold-rolled steel plates can be recycled, reducing resource waste and environmental pollution.| Carbon (C) | 0.42-0.50% |
