Wikipedia article

Steel can be smelted at a smelter by a dwarf with the furnace operator labor activated. It is an extremely durable metal and is highly valuable.

The method for making steel is unbearably accurate. 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.

Recipe

The recipe for steel is:

• One pig iron bar
• One iron bar
• One flux material
• One carbonaceous material (coke or charcoal)

When the above items are combined at a smelter, the product is two bars of steel; the carbon and flux are lost in the reaction, but the pig iron and iron are combined into steel.

Production chain

In terms of raw materials, the total required to produce the two steel bars is:

• Two units of iron ore, smelted into two iron bars
  • One iron bar is smelted into pig iron
  • One iron bar is used to produce the steel
• Two flux materials
  • One flux material is used to smelt pig iron
  • One flux material is used to produce the steel
• Two carbon materials
  • One carbon material is used to smelt pig iron
  • One carbon material is used to produce the steel.
• Four units of fuel if not using a magma smelter (this will usually be the same carbon material as above, for a total of six carbon units required in the non-magma version)

It will require a total of 4 smelting operations to produce the steel, but the carbon source is also used as the fuel when smelting in a normal smelter. Thus you require 4 units of fuel for the entire resource chain. Steel is different from most metals as it will still require fuel even if you are smelting with a magma smelter.

• Two units of fuel to smelt two units of iron ore into iron bars
• One unit of fuel to smelt one iron bar into pig iron
• One unit of fuel to produce the steel bars
