Iron and Chromium mixture called Steel. In Steel composition Iron-84% and Chromium-16%.

Potassium dichromate (K2Cr2O7) contain 35,361 % chromium.

Ruby is aluminium oxide; chromium is only a natural dopant, in traces. The concentration of chromium is not constant in rubies.

Chromium: 16-18,5 % Nickel: 10-14 % For details see the link below.

stainless steel does not rust due to the chromium placed within the composition. The chromium is used to form a chromium oxide layer stopping diffusion and in turn preventing corrosion.

The ruby's chemical composition is Al2O3, an aluminum oxide. The red color of a ruby, which is a kind of corundum, comes from chromium in it.

Iron mostly, 10% chromium and a dash (1-2%) of carbon.

Ruby is aluminium oxide (Al2O3) with chromium as an impurity.

Chromium - 19.5% Manganese - .40% Silicon - 1.25% Iron - .50% Nickel - 79 %
