HSLA Steel Ingots are the metal obtained from the smelting of iron ingots in Blast Furnace or Pulse Jet Furnace. They are used to make a wide variety of items such as tools as well as machines, engines and more. Steel tools are capable of mining all blocks that iron tools can. Considering bonus output of steel from smelting they outperform iron tools completely.
HSLA Steel Ingots can also be obtained from smelting steel tools and steel scraps using Pulse Jet Furnace.
RotaryCraft Handbook DescriptionEdit
"The steel ingot, made by smelting an iron ingot in a blast or pulse jet furnace, is the basis for all the machines, as only steel has sufficient tensile and shear strength to handle the loads applied by the machines."
