Q550NH Corrosion Resistant Steel Plate
weathering steel sheet Product Introduction
The grade of Q550NH corten steel plate consists of "yield strength", the first letters of the Chinese pinyin "Q" and "NH" of "weather resistance", the lower limit of the yield strength and the quality grade (A, B, C, D, E).
Q550NH corten sheet has a rust protective layer against atmospheric corrosion and can be used to manufacture low-alloy structural steel for vehicles, bridges, towers, containers and other steel materials. Compared with carbon steel, Q550NH corten steel sheet metal has better corrosion resistance in the atmosphere.
Q355NH corten steel sheet Application: Corten steel is mainly used for steel structures such as railways, vehicles, bridges, towers, etc. that are exposed to the atmosphere for a long time.
Q355NH corten weathering steel can also be used to manufacture structural parts such as containers, railway vehicles, oil derricks, harbor buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
