Steel is at the core of many cookware lines. It is comparable to solid cast-iron due to its raw finish but is lighter, unbreakable and won't chip, and will not retain odors. An alloy of iron and carbon, it is hard, durable and warp-resistant, and is impervious to metal objects, such as knives, forks and spatulas. Steel pans comply with demanding professional requirements, such as long pre-heating times, high-heat levels and intensive use, and are thermal shock-resistant and compatible with all heat sources, including induction. Commonly called "carbon steel", they come with different finishes including silver if intensely polished, or a blue or black finish from a heat treatment process which protects temporarily against oxidation.
