  1. Stainless steel is formed due to other metals present, that are resistant to corrosion. The main one is chromium, which is an excellent protector.

    Hardness in steel is due to other metals, as well as the carbon content. Chromium, vanadium and tungsten make steel extraordinarily hard. High carbon content makes steel hard but brittle.


  2. The person above me is right .The stainless steel is used in shaving blades

  3. a little clarification.

    steel doesn't "become stainless".

    There are many different types of steel, which is an alloy of iron and other element. The other elements determine things like hardness, corrosion resistance, etc. One element is chromium, which when added in the correct proportions, forms stainless steel. PS, there are many many different stainless steels, with different proportions.
