A: Three factors dominate:
- Hydrogen-based smelting costs ($40/tonne premium)
- African chrome supply chain disruptions
- Carbon border taxes (EU CBAM adding 12-18%)
Context-dependent. While we supply aluminum alloys saving 60% weight in aerospace/EV projects, stainless remains essential for:
- High-temperature parts (>550°C)
- Chloride-rich environments (offshore rigs)
- Medical implant biocompatibility
