Steel can be smelted at a Template:L by a Template:L with the Template:L labor activated. It is an extremely durable Template:L and is highly Template:L, worth just as much as Template:L.
Aside from Template:L, steel is the only material which can be used to build structures over Template:L. Template:Ls and Template:L made from steel are 33% stronger than equivalent Template:L objects.
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.
Recipe
The recipe for steel is:
- One Template:L Template:L
- One chunk of Template:L
- One chunk of Template:L (Template:L)
- One Template:L of Template:L or Template:L (plus an additional unit of Template:L if using a non-magma magma Template:L)
When the above items are combined at a Template:L, the product is two bars of steel; the refined coal and flux are consumed in the reaction, but the pig iron and iron are combined into steel.
Production chain
In order to make steel from scratch, the following materials are needed:
- Two chunks of Template:L
- Two chunks of Template:L
- Two units of Template:L (Template:L or Template:L)
- Three additional units of Template:L if using a regular smelter
The following steps are performed to produce two steel bars from the above materials at a normal smelter:
- Make iron bars - 1 Template:L + 1 Template:L = 1 Template:L bar
- Make pig iron bars - 1 Template:L bar + 1 Template:L + 2 Template:L = 1 Template:L bar
- Make steel bars - 1 Template:L + 1 Template:L bar + 1 Template:L + 2 Template:L = 2 Template:L bars
At a magma smelter, however, no fuel is required, reducing coal usage significantly:
- Make iron bars - 1 Template:L = 1 Template:L bar
- Make pig iron bars - 1 Template:L bar + 1 Template:L + 1 Template:L = 1 Template:L bar
- Make steel bars - 1 Template:L + 1 Template:L bar + 1 Template:L + 1 Template:L = 2 Template:L bars
Note that while pig iron is made directly from iron bars, steel must be made using hematite, so take care not to smelt all of your iron ore!
