Q355NH weathering steel plate (i.e. atmospheric corrosion-resistant steel) is one of the advanced series of steel in the world super steel technology, which integrates the new mechanism, new technology and new process of modern metallurgy.
Q355NH weathering steel plate is made of ordinary carbon steel and a small amount of copper, nickel and other corrosion-resistant elements. Q355NH weathering steel plate has the characteristics of toughness, plastic elongation, formability, weldability, wear resistance, high temperature and fatigue of high quality steel. Carbon steel is 2-8 times as common carbon steel, and coating performance is 1.5-10 times as common carbon steel. Q355NH weathering steel plate can be used for dilution, exposure or simplified painting. Q355NH weathering steel plate has the characteristics of rust prevention, corrosion resistance, long service life, thinning and consumption reduction, labor-saving and energy saving, which is conducive to the production of parts and users.
Q355NH weathering steel plate products are used to manufacture structural parts such as hydrogen sulfide corrosion containers, railway vehicles, oil derrick, seaport buildings, oil production platforms, chemical and petroleum equipment, etc.
