Metal vs. Steel: Is There a Difference? |

Steel, on the other hand, is an alloy of iron with varying amounts of carbon content (from 0.5 to 1.5 percent) [source: Merriam-Webster]. Steel, being an alloy and therefore not a pure element, is not technically a metal but a variation on one instead. It's partially composed of a metal, iron, but because it also has non-metal carbon in its chemical make-up, it's not a pure metal.

Stainless steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminum, carbon, etc. It is universally preferred for making kitchen utensils, because it does not affect the flavor of food and is easy to clean. Minimal maintenance and possible total recycling of stainless steel utensils also contribute to their popularity. It is called

Energy Use in US Steel Manufacturing - Robert B.

Based on the data from Fruehan et al. we can see that raw steel production from iron ore to steel using a basic oxygen furnace will require approximately 24.5 × 10 9 J per ton of steel produced. [4] This includes the reduction of raw iron ore into pig iron and then conversion of pig iron to steel. Alternatively, energy use with an electric arc furnace is often done with recycled steel rather

How stainless steel is made - material,

To make stainless steel, the raw materials—iron ore, chromium, silicon, nickel, etc.—are melted together in an electric furnace. This step usually involves 8 to 12 hours of intense heat. Next, the mixture is cast into one of several shapes, including blooms, billets, and slabs. and then it is cast into solid form. After various forming steps, the steel is heat treated and then cleaned and
