A105 carbon structural steel

A105 is the American ASTM standard number, which represents ordinary carbon structural steel. The name of this standard is “Carbon Steel Forgings for Pipe Components”. Since the standard only specifies one type of carbon steel forgings, A105 is considered a forging carbon steel grade. It is also a material code, which belongs to special steel and is a kind of cold forged steel. A105 is a low carbon steel forging similar to 20 steel.

A105 chemical element
C: ≤0.35
Cr: ≤0.3
Mn: 0.6-1.05
Mo: ≤0.12
Si: ≤0.35
S: ≤0.050
P: ≤0.040
Cu: ≤0.4
Ni: ≤0.4
V: ≤0.08
In the pipeline industry, A105 is widely used, especially in high temperature, high pressure and corrosion-prone environments. This is because A105 has excellent mechanical properties and corrosion resistance. It has high strength and hardness, can withstand high pressure and temperature, and has good toughness to absorb shock and vibration. In addition, A105 also has good processability and welding performance, making it easy to manufacture and repair.

During the manufacturing process, A105 typically requires forging and heat treatment. Forging can change the internal structure of a metal and improve its mechanical properties. Heat treatment can change the surface structure and hardness of the metal, further improving its mechanical properties and corrosion resistance. After completion of manufacturing, A105 requires rigorous inspection and testing to ensure that it meets ASTM standards and user requirements.
In addition to its application in the pipeline industry, A105 can also be used in other similar fields, such as chemical, petroleum, food and other industries. In these fields, A105 also needs to withstand high temperatures, high pressures and corrosive environments, so it also has broad application prospects.
In short, A105 is a high-quality carbon structural steel with excellent mechanical properties and corrosion resistance, and is widely used in pipelines and other similar fields. With the continuous advancement of technology and the continuous expansion of application fields, the application prospects of A105 are also broader.
