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
