# Corrosion Materials Selector Skill

## Purpose

The Corrosion Materials Selector Skill recommends materials of construction based on process conditions, corrosion mechanisms, and industry standards to ensure equipment reliability.

## Capabilities

- Corrosion mechanism identification
- Material screening
- Corrosion rate estimation
- Corrosion allowance calculation
- Material specification development
- Isocorrosion curve analysis
- Galvanic compatibility assessment
- Stress corrosion cracking evaluation
- Cost-benefit analysis

## Usage Guidelines

### When to Use
- Selecting materials for new equipment
- Evaluating corrosion failures
- Assessing process changes
- Specifying replacement materials

### Prerequisites
- Process conditions defined
- Chemical composition known
- Operating temperature/pressure specified
- Design life established

### Best Practices
- Consider all corrosion mechanisms
- Use conservative assumptions
- Reference industry standards
- Validate with experience data

## Process Integration

This skill integrates with:
- Equipment Sizing and Specification
- Process Flow Diagram Development
- HAZOP Study Facilitation
