How to Get Steel Ingot and Unlock Metallurgy Tech in Graveyard Keeper 2

In Graveyard Keeper 2, Steel Ingot serves as an essential crafting material sold by Bishop for 1 coin, required to fabricate machinery, tools, and town workshop upgrades.
Advancing into steel requires progressing through the Metallurgy tech tree to research Steel Smithing (120 red, 15 blue points) and Steel Casting (150 red, 20 blue points).
Acquiring Steel Ingot from Bishop
In Graveyard Keeper 2, Steel Ingot serves as an essential crafting material with a maximum stack size of 30. Early in your progression, acquiring steel can be handled directly by visiting Bishop, who sells Steel Ingot for 1 coin. In addition, studying a Steel Ingot requires 3 Science (see our science guide for research mechanics) and awards 20 red points and 25 blue points.

Unlocking Steel Smithing and Steel Casting
Unlocking Steel Smithing requires 120 red points and 15 blue points alongside prerequisite knowledge in Iron Products and 70 reputation with Jack. This breakthrough unlocks Steel Detail, Steel Screws, Steel Anvil, and Lantern II. Progressing further into Steel Casting requires 150 red points and 20 blue points, granting access to Engineering Details, Steel tools, and the Casting Table.

Forging Steel Detail and Equipment Upgrades
At the Steel Anvil workstation, players can process 1 Steel Ingot into 4 Steel Detail components. The Engineer perk grants +2 to this crafting result. Fabricating Steel tools at the Steel Anvil consumes 2 Stick, 2 Steel Detail, and 2 Engineering Details. In addition, 1 Steel Ingot crafts Engineering Details at Furnace II, and combines with Blue Crystal and 10 Faith at the Jewelry Table to assemble a Steel Zombie Collar — useful for outfitting advanced workers in our guide on how to make zombies work. These refined components also supply the Smithy in Town, where upgrading to Smithy III requires 12 Steel Screws, while mining coal and iron ore deposits is detailed in our resource location guide.
