Type 316 is a molybdenum bearing grade. The addition gives this grade better overall corrosion resistance properties than types 301 and 304 and higher creep strength at elevated temperatures.Type 316 gives useful service at room temperatures in sulfuric acid of concentration lower than 15% and higher than 85%. It also resists chloride attack and is often selected for use in marine atmospheres.

Type 316L with its 0.03 maximum carbon content is used in applications where is not possible to anneal after welding and where maximum corrosion resistance is required.

Corrosion Resistance: Good resistance to a wider range or chemicals than Type 304. Highly resistant to the complex sulphur compunds used in Pulb and Paper processing. Also resists attack of marine and corrosive industrial atmospheres.

Heat Resistance: Good oxidation resistance in intermittent service to 1600ºF and in continuous service to 1700ºF. Continuous use of 316 in 300ºF/1575ºF. range is not recommended but often performs well in temperatures fluctuation above and below this range. Type 316L is more resistant to carbide precipitation and can be used in the above temperature range.

Annealing: Heat to 1850ºF-2050ºF and cool rapidly. These grades cannot be hardened by thermal treatment.

Welding: Good characteristics suited to all standard methods. Use Type 316Cb, 316L or 309Cb filler rods or electrodes depending on application. Welded sections in Type 316 require post-weld annealing for maximum corrosion resistance (This is not required if Type 316L is used). Application include pulp and paper equipment, head exchangers, dyeing equipment, photographic developing equipment, propeller shafts, fittings and exterior architectural components in marine coastal areas.
