What is stainless steel?
A. Stainless steel is an alloy, which does exactly what its name implies: stains less than ordinary steel (iron). Yes, it can stain, discolor and rust, given the right circumstances. To make iron stainless, nickel and chromium are added in certain quantities, depending on the purpose it is being used for and the qualities required. The more chromium added to the mix, the softer the alloy becomes, something not desirable in a surgical instrument. Given that, quality medical stainless steel alloy is of a very specific, narrowly defined mix. A further aspect of making steel “stainless” is a repeated process of extracting surface impurities, mainly minerals. And the final high polish of the finished instrument puts a minute protective coating on it, also very important to make the instrument “stain less”. Whether the final product is highly polished or mat finished will make no difference in its stainless ability.
