"Stainless" or the official name is "stainless steel" is a general term used to call in the group with high corrosion resistance. Stainless is an alloy of iron and carbon. Which components are carbon, low chromium as main ingredients, about 10.5% or more to do the creation of chromium oxide film. (chromium oxide film: CrO2 or called passive film) invisible sticks. Tight surface makes steel, corrosion resistance, film protect. This is equivalent to put some paper 1 sheet on the building 20 layer. If the film surface is destroyed, no matter from the mechanical, chemical, or oxygen contained in the atmosphere. Even a few will react with chromium. Create a chromium oxide film replacement, new itself.
