## How they are linked

### 1. Material need

*Physical flow · Direct · Steel → Steam turbines and thermal power plants*

Building or running Steam turbines and thermal power plants needs steel.

### 2. Price link: main material

*Cost and price · Weak · Both ways*

Casings, rotors and frames are heavy steel forgings and castings. Even so, the link barely shows in the data, with monthly moves correlating at 0.09, because turbine prices are fixed when ordered and delivered years later, with metal costs often covered by escalation clauses.
