What are the classifications and applications of carbon steel tubes?

The classifications of carbon steel tubes are based on their carbon content and the resulting physical and mechanical properties. There are different grades of carbon steel tubes, each with specific uses and applications. Here are the classifications and applications of carbon steel tubes:

General carbon steel tubes:
Low-carbon steel: Contains a carbon content of ≤0.25%. It has low strength, good plasticity, and toughness. It is suitable for making welded structural parts, non-stress-bearing parts in machinery manufacturing, pipes, flanges, and various fasteners in steam turbine and boiler manufacturing. It is also used in automobiles, tractors, and general machinery manufacturing for parts such as hand brake shoes, lever shafts, and gearbox speed forks.

Low carbon steel tubes:
Low-carbon steel with a carbon content of more than 0.15% is used for shafts, bushings, sprockets, and some plastic molds. After carburizing and quenching, it provides high hardness and good wear resistance. It is suitable for making various automotive and machinery components that require high hardness and toughness.

Medium carbon steel tubes:
Carbon steel with a carbon content of 0.25% to 0.60%. Grades like 30, 35, 40, 45, 50, and 55 belong to medium-carbon steel. Medium-carbon steel has higher strength and hardness compared to low-carbon steel, making it suitable for parts with high strength requirements and medium toughness. It is commonly used in quenched and tempered or normalized states for manufacturing various machinery components.

These different types of carbon steel tubes find applications in industries like machinery manufacturing, automotive, steam turbine and boiler manufacturing, and general machinery manufacturing. They are used for producing a wide range of components and parts with specific mechanical and physical properties, catering to different industry needs.
