The pages
| Page | The failure that actually appears | Candidates |
|---|---|---|
| Materials for coastal architectural exterior | tea staining — a brown surface discolouration that removes no metal and ends the conversation about whether the right grade was chosen | 7 |
| Materials for high temperature exhaust and flue gas | thermal fatigue at restrained joints, and scale spalling that thins the section a cycle at a time rather than a year at a time | 2 |
| Materials for seawater piping | crevice corrosion at flanges, gaskets and under deposits, in lines that sit stagnant | 7 |
What these pages are for, and what they are not
They are a starting shortlist with the evidence attached. Each candidate links to a page showing where every figure came from and what we could not establish.
They are not a recommendation for your part. The screening property and the failure mode are rarely the same thing, which is the recurring point of this section and the reason each page has a section on it. Where the deciding property is one we have not sourced, the page says so and does not rank on it.
Earlier than a shortlist, start with how a selection actually runs. Once you have two finalists, the comparisons show the rows that do not compare. When you have chosen, write the record. If the question is really about a job rather than a pair of grades, the application pages are the better entry point.
What this section does not cover
- Regulated and safety-critical applications. Implants, pressure boundary, nuclear and aerospace primary structure are not generated from a template here, and will not be.
- Anything led by polymers, composites, concretes or coatings. The data layer does not cover them; see what it does cover.
- Cost, lead time and availability, which decide more selections than any property on these pages.
- Your operating conditions. Every page here assumes a generic version of its application and says so.
