Which step involves estimating potential corrosion rates?

• A. Rank risk
• B. Estimate potential rates
• C. Identify assets
• D. Plan monitoring

Answer: (B)

Estimating potential corrosion rates focuses on forecasting how fast corrosion could progress for an asset in its actual environment. This step takes environmental factors (such as temperature, humidity, salinity, and contaminants) and material properties (like alloys, coatings, and previous corrosion history) and translates them into a quantitative rate of loss, often expressed in millimeters per year or mils per year. That quantified rate is what drives risk assessment and helps decide where monitoring or mitigation will have the biggest impact.

The other steps are about different things: identifying assets is inventory and criticality of what needs protection; ranking risk is ordering assets by overall risk level; planning monitoring is about setting up surveillance and data collection once you know where the highest risk lies. Estimating potential rates is the step that provides the numerical basis for prioritizing actions.
