This article is about an older version of DF.

Steel is the best common metal for smithing most weapons and armor. Products made with steel also have a very high value, equal to that of gold.

Steel can be created at a smelter by a dwarf with the furnace operator labor activated.

Sedimentary Layers

To smelt steel, you will need iron ore, flux stone, and fuel. Flux is used to remove carbon during the smelting process, while fuel (coke or charcoal) puts it back in. The end result is steel: iron with just the right amount of carbon in it. The three ores of iron (hematite, magnetite, and limonite) can only be found in sedimentary layers, with the exception of hematite, which can occasionally be found in igneous extrusive layers. Furthermore, four of the five flux stones (calcite, chalk, dolomite, and limestone) are found only in sedimentary layers, as well as both coal ores (bituminous coal and lignite) for making coke fuel.

If you have no sedimentary layers at your fortress site, your only hope to make steel is with:

(Even if you find and use magma for your furnaces, you'll still need fuel as a reactant in the smelting process, so you'll be cutting down a tree and burning it to make charcoal for every bar of steel you manage to create.)

Recipe

Steel production is fairly complex compared to the creation of other alloys. Important note: in steelmaking, coke or charcoal is also used as an ingredient, apart from its use as fuel. A conventional (non-magma) smelter will require an additional unit of fuel in each reaction.

The first step is to create pig iron:

  • 1 bar of iron
  • 1 flux stone
  • 1 unit of carbon from fuel
  • 1 unit of fuel, or magma
Produces:
  • 1 bar of pig iron

The second step combines the pig iron with plain iron to produce steel:

  • 1 bar of iron
  • 1 bar of pig iron
  • 1 flux stone
  • 1 unit of carbon from fuel
  • 1 unit of fuel, or magma
Produces:
  • 2 bars of steel

The overall reaction consumes 2 bars of iron, 2 units of flux, and 2 units of fuel as ingredients (plus an extra 2 fuel at a conventional smelter for heating). This produces 2 bars of steel.

Remember that smelting iron ore also requires 1 unit of fuel at a conventional smelter, producing 4 bars of iron, which translates to half a unit of additional fuel used in the recipe above (although you will need a full unit up front.)
