welding corten steel Product Introduction
The Q235NH steel plate in GB/T4171-2008 is a structural steel that is resistant to atmospheric corrosion. Its minimum yield strength is 235 MPa and its tensile strength is between 360-510 MPa.
GB/T4171-2008 Q235NH weathering steel is a corrosion-resistant high-quality steel made by adding a small amount of weathering steel, copper, nickel and other elements to carbon steel. It has toughness, plasticity, casting, molding, welding, wear resistance, high temperature resistance, and fatigue resistance. and other properties; the weather resistance is 2 to 8 times that of carbon steel, and the coating is 1.5 to 10 times that of carbon steel. It can be used diluted, exposed or simplified for painting.
GB/T4171-2008 Q235NH weathering steel welding is mainly used for steel exposed to the atmosphere such as railway vehicles, bridges, and towers. Q235NH corten metal sheet can also be used to manufacture structures containing hydrogen sulfide corrosive media such as containers, rolling stock, oil derricks, port buildings, oil platforms and petroleum equipment chemical containers.
Mechanical properties of GB/T4171-2008 Q235NH atmospheric steel:
Tensile strength: 360MPa~510MPa
Yield strength: 215MPa~235MPa
