Q355NH weathering and corrosion resistant steel plate description

Q355NH weathering and corrosion resistant steel plate and other weather-resistant steel materials are added with Cu, P, Cr, Ni, Cr and other elements to make it have better atmospheric corrosion resistance, and its corrosion resistance is 2-8 times or even higher than that of ordinary steel plates. High, it can be exposed to the outside world or painted for use during use. Therefore, it is an economical, environmentally friendly and green steel grade.

Q355NH weathering and corrosion resistant steel plate are mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, iron towers, photovoltaics, high-speed projects, etc. Used in the manufacture of containers, railway vehicles, oil derricks, port buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
