Elevated Temperature Properties of A588 Weathering

In recent decades,bridge fires have become a major concern in the United States.Fire hazard in bridges can result in significant economic and public losses.New construction of bridges often use Weathering Steel (also known as Corten Steel),which has a corrosion-retarding effect since the steel forms a protective rust layer on its surface under the influence of the weather. Corrosion Risk Management Methods to Realize Long In order to realize long term durability of weathering steel bridges,one has to assess at the planning and/or designing stages,that atmospheric corrosiveness of the construction site is within the applicability limit of the weathering steel to be applied.Also,adequate maintenance is required to cope with unpredictable part in corrosion risks.
