Chromes Continental Alloys

Chromes. Commonly called chrome, the alloy referred to here is actually chromium. Chromium is added to steel in small quantities to improve strength, corrosion resistance and response to heat treatment. At 3% to 10% chromium, steel resists corrosion, but is not actually stainless. At 10.5% to 20% or more chromium, the steel is fully stainless.
