Stainless Steel and the passive layer Steel is an alloy of iron and carbon. Contrary to carbon steel, the presence of a minimum of 10.5 % chromium in the stainless steel gives it the property of corrosion resistance.

Sinus Drainage & Stomach Problems. One of the primary results of sinus congestion is drainage. Sinus drainage is expelled in two basic ways: through the nose and the back of the throat.
