The Research Situation and Development Trend of Weathering-Steel

Abstract

In modern society, due to the improvement of industrialized and development of marine economy, pollutants in the atmosphere and water aggravation corrosion of steel structure, annual worldwide economic losses due to corrosion is astronomical figures. Hence, atmospheric corrosion resistance of weathering steel has a broad market prospect. In addition, it also has excellent mechanics, welding and other properties. This paper mainly discusses the structure, production process, performance organization and the effect of various alloying elements on weathering steel.
