Steel is formed by Group of answer choices oxidizing some of the iron to iron oxides. combining iron, carbon and transition metals such as chromium and nickel. heating iron at high temperature for a long time. adding sand and heating to a high temperature.

combining iron, carbon and transition metals such as chromium and nickel.

Explanation:

Steels are alloys of iron and carbon. Steel is hard, tough and strong. The amount of carbon present in varies between 0.1 and 1.5% and it determines the hardness of steel. The higher the carbon content, the harder the steel produced. Also, the amount of heat treatment as well as presence of other elements determines the properties of steel produced.

Steel can be combined with other elements such as nickel, chromium, and manganese to produce various other alloys of steel . These alloys have various desirable properties than ordinary steel such as resistance to corrosion, high tensile strength and luster.
