Steel is the best common metal for smithing Template:L and Template:L. Products made with steel have a very high value, equal to that of Template:L.

Steel can be smelted at a Template:L by a Template:L with the Template:L Template:L 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 exploit magma for your furnaces, you'll still need the fuel in the smelting process, so you'll be cutting down two trees and burning them to make charcoal for every unit of hematite you manage to scrounge up.)

Recipe

Steel production is fairly complex compared to the creation of other alloys. Important note: in steelmaking, Template:L or charcoal is used as an ingredient, not as a Template:L. A conventional (non-magma) smelter will require 1 extra unit of fuel to power itself in each reaction.

The first step is to create Template:L:

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 Template:L stone
  • 1 unit of fuel
  • A power source (fuel, magma)
Produces:
  • 2 bars of steel

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

Remember that smelting the iron Template:L will also require 2 fuel at a conventional smelter.
