What is the material of carbon steel pipe?
1. Q235碳素结构钢管：
Q235 carbon structural steel pipe is one of the most common materials in carbon steel pipe. It has good plasticity and welding properties, and is suitable for low-pressure fluid transportation, machinery manufacturing and other fields for general purpose. The material has a low carbon content, moderate strength, and a relatively low price, making it an economical and practical choice.
2. Q345低合金钢管：
Q345 low-alloy steel pipe is a high-strength, low-alloy carbon steel pipe. Compared with Q235 steel pipe, Q345 steel pipe has higher tensile strength and yield strength, and better corrosion resistance. It is widely used in large-scale construction projects, bridges, machinery manufacturing and other fields, and is subject to greater pressure and load.
