Atmospheric corrosion of weathering steels

The term weathering steel describes a high-strength low-alloy composition consisting of a carbon steel base to which about 2% of alloying elements is added for corrosion resistance. These additions may consist of elements such as phosphorus, silicon, nickel, chromium, and copper within the limits prescribed in ASTM specifications A 242 and A 588.

In the conference the following will be considered:

  • 1. Background
  • 2. First specifications
  • 3. Requirements for the formation of protective rust layers
  • 4. Atmospheric corrosion data from different countries
  • 5. Stabilization (steady state) of rust layers
  • 6. From empirical status to scientific knowledge
  • 6.1Atmospheric corrosion mechanisms
  • 6.2 Advances in the knowledge of protective rust layers
  • 7.Effects
  • 7.1 Of environmental exposure conditions
  • 7.2 Of weathering steel characteristics
  • 8. Estimation of long-term atmospheric corrosion
  • 9. Evaluation of rust layers protective properties
  • 10. Latest developments
  • 10.1 New weathering steels
  • 10.2 Coatings
