How Many Types of Mild Steel Pipe Materials Are There?

Mild steel pipe is a widely used type of steel pipe. Its main characteristics are high plasticity and toughness, low strength, and it is suitable for some fields that do not require high strength but require high plasticity and toughness.

Types and features of mild steel pipe materials

There are many types of materials for mild steel pipes, mainly the following:

1. Q195 steel pipe

Low carbon, manganese, and silicon content are low, with good plasticity and toughness, suitable for manufacturing general-use steel pipes under low loads.

2. Q215 steel pipe

Moderate low carbon, manganese, and silicon content, slightly higher strength than Q195, suitable for use under general loads.

3. Q235 steel pipe

Low carbon, manganese, and silicon content are similar to Q215, with good mechanical properties and processing properties, and wide applicability.

4. Q345 steel pipe

Manganese and silicon content are increased, higher strength than Q235, suitable for occasions with high loads and high wear resistance requirements.

Commonly used mild steel pipe materials and application fields

1. Q195 steel pipe

Q195 steel pipe is a commonly used mild steel pipe material with good plasticity and toughness. It is suitable for manufacturing general-purpose steel pipes, flexible pipes, welded pipes, vertical pipes and water and gas pipes under low load. It is widely used in construction, machinery, electricity, chemical industry, agriculture, urban infrastructure and other fields.

2. Q235 steel pipe

Q235 steel pipe is a commonly used mild steel pipe material with high strength and plasticity. It is suitable for manufacturing general-structure steel pipes, flexible pipes, welded pipes, pipes for machinery manufacturing, etc. It is widely used in construction, machinery, electricity, chemical industry and other fields.

3. 20# steel pipe

20# steel pipe is a mild steel pipe material, mainly composed of five elements: C, Si, Mn, S, and P. It has low strength and good surface finish. It is usually used to manufacture mechanical parts, automotive parts, boiler tube, etc. It is widely used in industrial fields such as automobiles, aviation, shipbuilding, and petroleum.

Summary

Compared with other steel pipes, mild steel pipes have good plasticity and toughness, and are suitable for some fields that do not require high strength but require high plasticity and toughness. Mild steel pipes of different materials are suitable for different occasions, and users can choose according to actual needs.
