PRODUCT DETAILS

Product introduction

Q355 carbon steel round bar is a low alloy high-strength structural steel widely used in fields such as bridges, vehicles, ships, construction, pressure vessels, and special equipment. Among them, "Q" represents the yield strength, and 355 indicates that the yield strength of this steel is 355MPa.

Q355 carbon steel round bar, as a low alloy high-strength structural steel, has a wide range of applications. The specific applications are as follows:

In the field of architecture, it is widely used in the construction of bridges, high-rise and large buildings, industrial factories, large industrial equipment foundations, oil drilling platforms, and can also be used for the reinforcement and renovation of old buildings.

In the field of vehicle manufacturing, Q355 carbon steel round bars have good fatigue resistance and are suitable for manufacturing automotive components, such as wheels, engine parts, etc.

In the field of shipbuilding: Q355 carbon steel round bars have excellent corrosion resistance and are suitable for manufacturing certain components of ships.

In the field of petrochemicals: Due to its excellent corrosion resistance and fatigue resistance, Q355 carbon steel round rods can be used to manufacture petroleum pipelines, chemical equipment, etc.
