What is the material of steel pipe


Steel pipe is a kind of steel with a hollow cross-section, whose length is much greater than its diameter or circumference. According to different materials, steel pipes can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes. Carbon steel pipes are mainly composed of iron and carbon, and may contain other elements. For example, high carbon steel has a higher carbon content and higher strength, but poor corrosion resistance. Alloy steel pipes contain a certain proportion of alloying elements, such as chromium, molybdenum, steel, manganese, copper, etc., and their strength, toughness, corrosion resistance, wear resistance and other properties are greatly improved compared with carbon steel pipes. Stainless steel pipes are composed of elements such as iron, chromium, nickel, etc., and have good corrosion resistance, toughness and strength. They are often used in high-end construction, home decoration, food processing and other fields. In addition, there are high-carbon carbon steel pipes such as Q235, which have good strength and hardness and are suitable for the manufacture of bridges, ships, vehicles, etc.
