Q355NHD steel plate characteristics

Q355NHD steel: where Q stands for yield strength, NH stands for weather resistance, and D stands for quality grade (A, B, C, D, E) composition. It belongs to weather-resistant structural steel, mostly used in construction, bridges, and railway vehicles. Of course, Q355NHD grade steel is also an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It is a low-alloy steel series between ordinary steel and stainless steel. Weathering steel Q355NHD is added by ordinary carbon steel. It is made of a small amount of corrosion-resistant elements such as copper and nickel. Q355NHD steel sheet has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.
