Q355NHD-Z15, Q355NHD-Z25, Q355NHD-Z35 steel plate
Q355NHD-Z15, Q355NHD-Z25, Q355NHD-Z35 steel plate characteristics: It has the characteristics of high-quality steel such as strength and toughness, plastic elongation, forming, welding and cutting, abrasion, high temperature, fatigue and so on.
Q355NHD-Z15, Q355NHD-Z25, Q355NHD-Z35 steel plate performance specification: GB/T4171.
Q355NHD-Z15, Q355NHD-Z25, Q355NHD-Z35 steel plate grade introduction:
Grade analysis, Q represents yield strength, NH represents weather resistance, and D represents the composition of quality grades (A, B, C, D, E). Q355NHD belongs to weather-resistant structural steel and is mostly used for construction, bridges, and railway vehicles. Of course, Q355NHD-Z15, Q355NHD-Z25, and Q355NHD-Z35 steel plates are also atmospheric corrosion-resistant steel plates, also known as weathering steel plates. It is a low alloy steel between ordinary steel and stainless steel. Q355NHD weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel.
