Products Description
Q295GNH Corten Steel Plate is an atmospheric corrosion-resistant steel, also known as corten steel. It is made from ordinary carbon steel with the addition of approximately 0.25% copper, 0.30% nickel, and other corrosion-resistant elements.
Q295NH weathering steel plate has the characteristics of high-quality steel, including a yield strength ≥ 295 MPa, tensile strength of 440–580 MPa, toughness (room temperature impact energy ≥ 27 J), as well as excellent ductility, formability, weldability, and machinability, along with wear resistance, high-temperature resistance, and fatigue resistance.
Meanwhile, Q295NH weathering steel also offers corrosion protection, extended service life (typically over 30 years), material thinning, and reduced consumption.

Application
Q295NH weathering steel plate is primarily used in railways, vehicles, bridges, towers, and other steel structures that are exposed to atmospheric conditions for extended periods.
The plate thickness typically ranges from 6 to 50 mm, with a yield strength of over 295 MPa, tensile strength between 440 and 580 MPa, and room temperature impact energy ≥ 27 J.
It combines excellent toughness, ductility, and fatigue resistance, making it suitable for projects requiring high load-bearing capacity, impact resistance, and long-term durability.
Q295NH weathering steel plate is also widely used in the manufacture of containers, railway vehicles, oil platforms, port buildings, and containers for chemical and petroleum equipment exposed to corrosive media such as sulfur and argon.
In these applications, Q295NH weathering steel can significantly extend service life (typically over 30 years), reduce material consumption and maintenance costs, while maintaining strong structural safety and durability.
