Graveyard Keeper 2 Steel Ingots and the Steel Anvil

The Bishop at the Royal Foundry is the only vendor community data lists for Steel Ingots.

You buy through his "High-quality steel" conversation, in lots of 1, 10, 50 or 100 — searching his ordinary stock will not show them.

Neither wikily.gg nor Fextralife lists a crafting recipe for the ingot itself, so plan your steel budget around buying it.

The Foundry is beneath the bathhouse on the north side of The Town, and the route there is a quest chain rather than a door.

After Heart of the Swamp, ask Larry about the portal, follow Any Portal in a Storm to Gunter, and ask Jack about the water tunnel.

Win Closing the Western Floodgate and both Eastern Floodgate battles, then win Break Through to the Bathhouse Basement.

Speak with the former Bishop there and choose "High-quality steel" to start the steel branch.

Jack, the workshop foreman, asks you to get high-quality steel from the Royal Foundry.

Bring him 3 Steel Ingots. The reward is 10 reputation with Jack and 3 Town Gratitude.

Completing it opens Factory Tour, the next step in Jack's line.

Steel Smithing (120 red, 15 blue) needs Iron Products and 70 reputation with Jack. It unlocks Steel Detail, Steel Screws, the Steel Anvil and Lantern II.

Steel Casting (150 red, 20 blue) adds Engineering Details, Steel tools and the Casting Table.

Steel Equipment (160 red, 10 blue, after Steel Instruments II) unlocks Steel Armor and the Steel Sword.

Steel Works (175 red, 20 blue, after Smithy II) unlocks the Engineering Kit, Supply: Steel Tools and the Smithy Grindstone.

The Steel Anvil is built in the Yard for 4 Steel Ingots and covers 47 recipes across Smithing mastery 1 to 15.

Zombies can work it, and its Hardening Bucket extension enables 17 of those recipes.

It makes the whole steel tool set — axe, hammer, pickaxe, shovel — plus the Steel Sword, Steel Armor, Master Sword and Master Armor.

Steel tools (2 Stick, 2 Steel Detail, 2 Engineering Details) give +4 Smithing mastery in the tool belt, which opens higher recipes for a zombie smith.

The Steel Zombie Collar (1 Steel Ingot, 1 Blue Crystal, 10 Faith) supports corpses with up to 99 red skulls, against 10 for gold.

Studying a Steel Ingot at the Study Table pays 20 red and 25 blue tech points — worth doing once.
