A36 carbon steel bar has a carbon content of approximately 0.26-0.29%, which makes it relatively low in carbon compared to other carbon steel grades. This low carbon content contributes to its excellent weldability, as it can be easily welded without the risk of brittleness or cracking.

A36 carbon steel pipe refers to a type of carbon steel pipe made from ASTM A36, which is a low carbon steel with good strength and formability. ASTM A36 is a widely used structural steel grade that is commonly used in construction and other heavy-duty applications.

A36 carbon steel coil is a commonly used carbon steel material with excellent mechanical properties and a wide range of applications. It is made from an iron alloy with a lower carbon content and has good castability and workability.

A36 carbon steel plate is characterized by its good plasticity, weldability, and mechanical properties, making it commonly used in industries such as construction, manufacturing, and shipbuilding for applications involving structural components, machinery parts, and general fabrication.
