Q355NH steel is mainly to add other chemical elements in the nickel, copper. These elements enhance the basic performance of ordinary carbon steel. Q355 NH steel is a weathering resisting steel. Q355 NH atmospheric corrosion resisting structural steel is widely used to building shipping containers and offshore containers.
