McNelly.com says, " The basic resistance of stainless steel occurs because of its ability to form a protective coating on the metal surface. This coating is a "passive" film which resists further "oxidation" or rusting. The formation of this film is instantaneous in an oxidizing atmosphere such as air, water, or other fluids that contain oxygen. Once the layer has formed, we say that the metal has become "passivated" and the oxidation or "rusting" rate will slow down to less than 0.002" per year (0,05 mm. per year). Unlike aluminum or silver this passive film is invisible in stainless steel. It's created when oxygen combines with the chrome in the stainless to form chrome oxide which is more commonly called "ceramic". This protective oxide or ceramic coating is common to most corrosion resistant materials. Halogen salts, especially chlorides easily penetrate this passive film and will allow corrosive attack to occur. The halogens are easy to recognize because they end in the letters "ine". Listed in order of their activity they are:
- fluorine
- chlorine
- bromine
- iodine
- astatine.

Why were the builders able to build the Hoover Dam and get the concrete to dry?
Concrete does dry as it solidifies, but the water used in the mix does not evaporate and leave the remaining components of the concrete in place as a solid. When concrete sets the water chemically reacts with the solids and is incorporated into the now solid material. The main problem with the setting of the concrete in Hoover Dam was to remove the heat generate in the setting process. The concrete was poured in such thick blocks that the internal temperature would have risen to damaging levels without special procedures to remove this heat. Coolant was circulated through pipes laid in the concrete to remove this heat.
The contractor got concrete on your house when he built your wheelchair ramps how do you get it off?
This is a little tricky because concrete is very hard; you can undoubtedly get it off by chiseling it, but you run the risk of damaging the wall of the house underneath.
