GB/T 4171 Q355NH weathering steel Introduction: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.
