Overview of Q195, Q215, Q235, Q255, Q275, Q345, and 20#10# Carbon steel pipes

Carbon steel pipes are widely used in various industries, including oil and Gas, due to their durability and strength. In China, there are several grades of carbon steel pipes that are commonly used, such as Q195, Q215, Q235, Q255, Q275, Q345, and 20#10#. These grades have different chemical compositions and mechanical properties, making them suitable for different applications.

Q195 is a low carbon steel Grade with good plasticity and toughness. It is commonly used for making structural components, such as beams and columns, as well as for general engineering purposes. Q215 is a medium carbon steel grade with higher strength and hardness compared to Q195. It is often used for manufacturing machinery parts and components.

Q235 is a carbon steel grade with good weldability and machinability. It is widely used in the construction industry for making structural components, such as bridges and buildings. Q255 is a high carbon steel grade with excellent strength and wear resistance. It is commonly used for making cutting tools and machine parts that require high hardness.
Dry Cooler
Q275 is a carbon steel grade with higher strength and toughness compared to Q235. It is often used for manufacturing heavy machinery and equipment. Q345 is a low alloy steel grade with good weldability and cold forming properties. It is commonly used for making pipelines and pressure vessels in the oil and gas industry.

20#10# is a carbon steel grade with good weldability and machinability. It is often used for making mechanical parts and components. These carbon steel grades are widely available in China, and there are many Suppliers that offer Factory direct supply of carbon steel pipes.
