Steel Production
Controlled production of iron-carbon steel, anchored here to Huntsman's 1740s crucible/cast-steel process in Sheffield; later Bessemer and open-hearth methods represent separate bulk steel scaling steps.

| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Iron Working (iron_working) | required | 86% | textbook | Steel production requires prior ironworking because steel is an iron-carbon alloy made from iron feedstocks. |
|
| Advanced Metallurgy (Medieval) (advanced_metallurgy_medieval) | historical_predecessor | 78% | review | Crucible steel followed earlier iron and steelmaking craft, including cementation and medieval blast-furnace metallurgy. |
|
| Blast Furnace (blast_furnace) | commercial_or_scaling_dependency | 76% | review | Blast furnaces supplied pig iron for subsequent steel processing and became major scaling infrastructure, but they are not the defining invention of Huntsman's crucible steel. |
