Electropolishing to Enhance Corrosion Resistance
This presentation explains
in detail the process of electropolishing, including:
- How it works
- When it works
- Why it works
Attendees will learn the advantages of electro-
polishing, as well as which applications benefit most from the process. We will also examine quality control criteria and case studies.
Combating Corrosion Through Materials Selection
Metals corrode for different reasons, each with its own mechanism. We will discuss some of the common forms of corrosion such as:
- Uniform corrosion
- Pitting
- Stress corrosion cracking
Understanding the degradation mode is key to controlling and preventing corrosion. Careful material selection, good design and quality fabrication can avoid the most serious corrosion problems. Using case histories, this presentation will discuss material issues in the hygienic industry.
Passivation of Stainless Alloys
This information will benefit process engineers, facility engineers and managers, and anyone concerned with cleaning and passivating newly installed equipment or derouging/descaling existing equipment with evidence of red rouge or black surface oxidation.
Topics of discussion will include:
- Definition and Methodology of Passivation
- Surface Chemistry and Corrosion Resistance
- Characteristics of the Passive Layer
- Passivation Acceptance Criteria ("Figures of Merit")
- Case Studies - A Practical Overview Of Corrosion
- How Long Will Passivation Last?
Rust or Rouging: What is the Difference?
It's stainless steel; it shouldn't rust—or should it? In this session we will present a study of the three different forms of rouge. We will also answer these questions:
- What is rouging?
- What causes it?
- How can you control it?
AL-6XN Alloy and Hastelloy C-22 Fabrication, Welding and Surface Finish
This discussion will examine high nickel and 6% molybdenum alloys. We will address their use for sanitary applications and cost comparisons for materials and installation.
