Q235 steel is equivalent to Japanese SS400 grade steel in application, with the only difference being that SS400 steel only requires S and P composition<0.050. Q235 has requirements for more elements C, Si, Mn, S, and P. The yield strength of Q235 is>235Mpa, which is almost the same as SS400 245Mpa. Q represents the yield of the material, while 235 refers to the yield value of approximately 235MPA of the material. As the thickness of the steel plate increases, the yield value decreases. It is widely used in construction and engineering structures.

Q235 Carbon Steel Square Bar is a type of carbon steel bar that is widely used in various industrial applications. It is made from high-quality carbon steel and meets the ASTM A36 and SS400 standards, ensuring its high quality and reliability.

Q235 Carbon Steel Square Bar is often used in construction, bridge girders, columns, and other structural steel components. It is also suitable for use in manufacturing, mining, and other industries that require high-quality steel materials. The steel bar has good toughness and wear resistance, making it suitable for use in harsh environments.

Q235 square steel has been widely used in multiple fields.

In the field of construction, Q235 steel is often used to manufacture steel structure buildings. Due to its high strength, good toughness, and ability to withstand large loads, it is widely used in high-rise buildings, large-span bridges, factories, and other places.
Q235 steel is also widely used in the automotive industry. Cars are composed of numerous components, many of which require the use of steel. Q235 steel has good plasticity and machinability, and can be manufactured into various shapes of components, such as car bodies, engine mounts, suspension systems, etc.

In addition, Q235 steel can also be applied in the following fields:

It is widely used as mechanical parts with low performance requirements.
Grade C and D steel can also be used as steel for certain professional purposes.
Mold handles and other unimportant mold parts.
Q235 steel is used as the punching material, which is quenched and used directly without tempering, with a hardness of 36-40HRC, solving the problem of the punching head breaking during use.
