Chemical properties of Q235NH weathered steel plate
The full name of Q235NH corten sheet is atmospheric corrosion-resistant hot steel, also known as corten steel and corrosion-resistant steel. Q235NH corten steel sheet is widely used in: containers, power plant chimneys, railway engineering and other outdoor steel.
Q235NH weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements added. It has the characteristics of high-quality steel such as strength, plastic extension, shaping, welding and cutting, abrasion, high temperature, fatigue, etc. In addition, Q235NH weathering steel sheet weather resistance It is 2 to 8 times that of ordinary carbon steel.
Q235NH corten sheet has the characteristics of rust resistance, anti-corrosion and life extension of components, thinning and consumption reduction, saving labor and energy.
