Q355NH Corrosion Resistant Steel Plate

Q355NH corten steel is an atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It complies with China's GB/T 4171 standard and is a kind of weather-resistant steel.

Q355NH corten steel material grade indicates: "Q" is the first letter of the pinyin for yield; "355" means that its yield strength is 355MPa; "NH" is the first letter of the pinyin for weather resistance.

Q355NH weathering steel characteristics: Atmospheric corrosion-resistant steel. Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements added. It has the characteristics of steel such as strength, plasticity, shaping, welding and cutting, abrasion, high temperature, and fatigue resistance. ; At the same time, it has the advantages of rust resistance, corrosion resistance and life extension of components, thinning and consumption reduction.

Q355NH weathering metal Application: Weathering steel is mainly used for steel structures exposed to the atmosphere such as railways, vehicles, bridges, and towers.

In addition, Q355NH weathering plate can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, harbor buildings, oil production platforms, and containers containing corrosive media in chemical and petroleum equipment.
