Profile
Ansteel’s bridge steel applied in the hong kong-zhuhai-macao bridge
Ansteel has been leading the development of new products and technologies in domestic bridge steel. Ansteel has developed a series of new generation bridge steel with high-performance, high strength, good low-temperature brittleness and good atmospheric corrosion resistance and anti-brittle fracture as well as high anti-fatigue and creepage. Characteristics and types
The key technology The application to domestic and international project of Ansteel's bridge steel shows that the development path of bridge steel in Ansteel is from low-carbon steel,low-alloy steel to high-performance steel, which is in line with international development trend of bridge steel.High-perfomance bridge steel of Ansteel includes low-alloy high-strength bridge steel with yield strength of 420~690MPa, atmospheric corrosion resistant bridge steel with the yield strength of 345~690MPa (NH series) and marine atmosphere corrosion resistant bridge steel with the yield strength of 235~420MP (NHY series).Many critical process technologies were applied: low-carbon, ultra-low carbon,micro-alloy technology, clean steel melting and controlling technology,multi-phase structure adjusting and controlling technology,auxiliary welding material and welding process technology. Characteristics
Various specifications:Thickness:16~80mm, width:900~5200mm,length:max.25000mm; unit weight of finished product:max.~25.8t
