How is Alloy Steel Made?

　　Like other steels, alloy steel manufacturing begins with the procurement of iron, either through mining or recycling. Additional alloying elements are selected based on desired properties — chromium for corrosion resistance, manganese for toughness, molybdenum for heat resistance, etc. From there, raw iron is melted in an electric arc furnace with temperatures reaching more than 2,900°F. Refinement processes like Argon Oxygen Decarburization are used to remove impurities such as excess carbon or sulfur.

　　Alloying elements are also added through these steps, but the timing depends on the element. For example, manganese and chromium are added during the melting process because they’re integral to the formation of the steel matrix. Other elements like nickel and molybdenum are added later during the refining process to prevent losses during melting.

　　Further refinement processes like vacuum degassing or electroslag remelting may be employed to further enhance the final product. From there, the alloy steel can be cast into slabs, ingots, billets, and more before being rolled/forged and heat treated.
