In addition, the material report of carbon steel square pipe usually includes information on both chemical composition and mechanical properties. Chemical composition mainly includes the content of carbon, silicon, manganese, phosphorus, sulfur and other elements, the content of these elements will directly affect the mechanical properties and plasticity of steel. Mechanical properties refer to the performance of the material under mechanical action, including tensile strength, yield strength, elongation, etc., which is a key indicator to measure the quality of carbon steel square pipe.

The volume calculation formula of carbon steel square pipe is: volume = length × width × height, that is, V = lwh.

Please note that the specific chemical composition, mechanical properties and application areas may vary depending on the manufacturer and market needs. Therefore, in the selection and use of carbon steel square pipe, it is necessary to make a reasonable choice according to the specific application environment and requirements.
