Q345GNHJ corrosion-resistant steel
Q345GNHJ steel has the high resistance to atmospheric corrosion hot rolling steel,also known as boarding steel, corrosion-resistant steel,Q345GNHJ steel is widely used in containers,power plants chimneys,railway engineering and other outdoor steel,weathering steel in the ordinary steel and stainless steel between the cheap low-alloy steel series,in the modern metallurgy into the new mechanism,new technology and new technology to sustainable development and innovation,and is one of the world's leading level of super steel technology series of steel.
The Q345GNHJ Weathering steel from the carbon steel to add a small amount of copper,nickel and other corrosion-resistant elements, with high-quality steel tough,plastic extension,forming,welding,abrasion,high temperature, fatigue and other characteristics;Weather ability is 2 to 8 times that of carbon steel,coating is the carbon steel 1.5 to 10 times,and can be reduced use,bare use or simplify the use of painting.Q345GNHJ steel has a rust-resistant,so that members of the anti-corrosion life extension,thinning and reducing consumption,the provincial energy-saving features,so that component manufacturers, users benefit.
