The ASTM A588 specification is the Standard Specification for High-Strength Low-Alloy Structural Steel , up to 50 ksi Minimum Yield Point, with Atmospheric Corrosion Resistance for applications where strength and durability are needed. The required ASTM G101 Corrosion Resistance Index must be ≥ 6.0.
Weathering steel refers to the steel grades used for structural and mechanical parts that are subjected to atmospheric corrosion for a long time, such as bridges, docks, chimneys, oil storage tanks, oil storage tanks, chemical equipment and containers that withstand atmospheric corrosion.
The size range of ASTMA588 weather-resistant steel plate, weather-resistant steel plate as an environmentally friendly steel, its performance and characteristics compared with ordinary steel, it has better economy and can reduce production costs. Weathering steel refers to the type of steel whose oxygen content in the atmosphere is about 0.1%, and the surface of the steel plate is corroded by corrosion (including salt spray, damp heat, etc.).
Weathering steel is widely used in various marine structures and projects, such as seaports and coastal facilities, ships and their infrastructure, etc.
In addition to the typical application in welded bridges and buildings, the specification is also commonly used in passenger rail cars.
