Steel is one of few materials that can resist melting when immersed in magma. Weapons and armor made from steel are 33% stronger than equivalent iron objects, making it second only to Adamantine for creating military equipment.
The method for making steel may seem complex but it is an accurate representation of the process, and not too bad when the overall utility of the resulting material is considered.
The recipe for steel is:
- One pig iron bar
- One iron bar
- One flux material
- One of coke or charcoal (can be used simultaneously as fuel for a non-magma smelter operation)
 Production chain
The following amount of materials are needed to produce two steel bars:
The following steps are performed to produce two steel bars from the above materials:
- Make pig iron bars (creates one pig iron bar)
- Make steel bars (creates two steel bars)
The tasks Make Pig Iron Bars and Make Steel Bars use the same materials at either smelter. At a normal smelter, the refined coal is needed as a reagent but will also act as the fuel needed for the smelting operation. At a magma smelter, the refined coal is needed only as a reagent.
If you have embarked on a map which does not have ready access to coal or flux, another possible, though expensive, way to obtain Steel is to buy out all the low quality steel weapons and armor from the Dwarven caravan and designate them for melting.
