Why Does Stainless Steel Rust? The Complete Guide

Stainless steel contains iron, carbon, and anywhere from 12-30% chromium. Stainless steel encompasses other elements like nickel and manganese, but chromium is the key element that makes it rust-resistant. When the surface of typical steel is exposed to oxygen, it always forms oxide (Fe2O3), which has a popular red rust color.
