Processing and use
Processing
- Product form, thermal history and manufacturing route materially affect performance.
Applications
- Heat-treatment fixtures
- Chemical equipment
- Legacy nuclear steam-generator components
Selection considerations
- Nuclear-water stress-corrosion history requires application-specific review.
- Alloy 690 is preferred in many modern nuclear pressure-boundary applications.

Supply and sustainability
Availability and lead time depend on grade, product form, certification and regional supply chain.
Segregated recovery and closed-loop recycling improve material efficiency where practical.
