鞍钢科研硬实力助力多个国家重大项目

Core Viewpoint - Weathering steel, a low-alloy steel with added elements, is essential for construction and infrastructure, providing corrosion resistance without the need for traditional coatings [1] Group 1: Product Characteristics - Weathering steel forms a protective oxide layer in natural environments, offering similar rust protection as traditional coatings while avoiding organic volatile emissions and maintenance [1] - The formation of the oxide layer takes several years and can lead to issues such as rust liquid dispersion and streaking during the process [1] Group 2: Technological Innovation - An innovative "weathering steel rust layer stabilization treatment technology" has been developed by Angang's researchers to expedite the formation of the protective oxide layer [1] - This technology has been implemented in significant projects, including the Yan-Chong Expressway crossing the Daqin Railway and the largest weathering steel bridge in China, the Linyi Yellow River Bridge, contributing to local ecological protection [1]
