Q460NH is a high-strength structural steel with good weather resistance and corrosion resistance. Q460NH forms a dense oxide layer (weather-resistant layer) in the atmospheric environment, which can effectively prevent further corrosion on the steel surface. This oxide layer forms quickly and can form a protective layer in a shorter period of time, reducing the need for maintenance and repair.
Q460NH has good atmospheric corrosion resistance and can resist the erosion of acid rain, salty fog and other atmospheric pollutants. It is suitable for use in humid and corrosive environments.
