Q355NH Application:

Q355NH steel has a protective layer of rust resistance to atmospheric corrosion, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel. Compared with carbon steel, Q355NH steel has better corrosion resistance in the atmosphere. Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering resisting steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent.
Mainly for railway, vehicles, bridges, towers and other exposed steel used in the atmosphere. Q355NH can also be used in the manufacture of containers, rolling stock, oil derrick, harbor construction, oil platforms and oil equipment chemical containers and other structures containing hydrogen sulfide corrosion medium.
