GB/T4171 Q355NH Weathering Steel feature and application

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.

Chemical composition for Q355NH:

Mechnical property for Q355NH:

Q355NH steel feature:
Atmospheric corrosion resistant steel, weathering steel from carbon steel to add a small amount of copper, nickel and other elements made of corrosion-resistant, high-quality steel with a tough, plastic casting, forming, welding, abrasion, heat, fatigue and other characteristics; at the same time, it resistant to rust, corrosion resistant components make life extension, thinning saving.

Q355NH steel Application:
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.
