Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel’s hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.
The Q275 steel grade indicates the chemical composition and mechanical properties of the steel. It offers moderate strength and durability, making it suitable for applications in the marine environment.
The process of producing carbon steel coils usually includes three steps: raw material pretreatment, cold rolling and heat treatment. In the pretreatment process, staggered lamination and coiling of materials are involved. In the process of cold rolling, the carbon steel roll needs to go through many pressing, drawing and cutting processes. In the heat treatment process, welding molding, to obtain the product.
