Overview
SS 316L Tubes is an improved version of Alloy 304, with the addition of molybdenum and slightly higher nickel content. The resultant composition of AISI 316L Tubes gives the steel much increased corrosion resistance in many aggressive environments. The molybdenum makes Type 316L Pipes more resistant to pitting and crevice corrosion in chloride-contaminated media, sea water and acetic acid vapours. The lower rate of general corrosion in mildly corrosive environments gives Type 316L Tubes good atmospheric corrosion resistance in polluted marine atmospheres.
It is the preferred steel for use in marine environments because of its greater resistance to pitting corrosion than other grades of steel. The fact that it is negligibly responsive to magnetic fields means that it can be used in applications where a non-magnetic metal is required. In addition to molybdenum, 316 also contains a number of other elements in varying concentrations. Like other grades of stainless steel, marine grade stainless steel is a relatively poor conductor of both heat and of electricity when compared to metals and other conductive materials.
