carbon pipe

Low carbon steel pipe is carbon steel with a carbon content of less than 0.25%. It is also called mild steel because of its low strength, low hardness and softness. It includes most ordinary carbon structural steel and some high-quality carbon structural steel. Most of them are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatments.

The annealed structure of seamless low carbon steel pipe is ferrite and a small amount of pearlite, which has low strength and hardness and good plasticity and toughness. Therefore, it has good cold formability and can be cold formed by curling, bending, stamping and other methods. This steel also has good weldability. Low-carbon seamless steel pipe generally refers to steel with a carbon content between 0.10 and 0.25%. This type of steel has low hardness and good plasticity, and is easy to use cold plastic deformation forming process, welding and cutting. It is often used to make chains, rivets, and bolts. , axis etc.

Types and characteristics of low carbon steel pipe materials

Low carbon steel pipe is a widely used type of steel pipe. Its main characteristics are high plasticity and toughness and low strength. It is suitable for some fields that do not require high strength but require high plasticity and toughness. There are many types of materials for low carbon steel pipes, the main ones are as follows:

Q195 steel pipe: low carbon, low manganese and silicon content, good plasticity and toughness, suitable for manufacturing steel pipes for general use under low load.

Q215 steel pipe: low carbon, moderate manganese and silicon content, slightly higher strength than Q195, suitable for use under general load.

Q235 steel pipe: Low carbon, manganese, and silicon content are similar to Q215. It has good mechanical properties and processing performance, and has wide applicability.

Q345 steel pipe: increased manganese and silicon content, higher strength than Q235, suitable for occasions with higher load and high wear resistance requirements.
