In principle, stainless steels should be in the passive state in soils, but the presence of water and aggressive chemical species such as chloride ions, sulphates and as well as types of bacteria and stray current, can cause localised corrosion. In such aggressive environments, stainless steel piping buried in soils should therefore be coated.

Melting point of Austenitic Stainless Steel is 550-640 C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs.

Stainless steel is an iron alloy that has a minimum Chromium content of 10.5 per cent. The Chromium content produces a thin chromium oxide film on the steel's surface called a passivation layer. This layer prevents corrosion from occurring on the steel surface; the greater the amount of Chromium in the steel, the greater the corrosion resistance.
