Stainless steel 316 tubes are hollow tubes which permit well controlled better circulation and movement of fluids. 316 stainless steel tubes are produced by Metline by two distinct methods which result in either a welded or seamless type of tube.

  • SS 316 Tubes sizes are specified in millimeter or in inches by outside diameter
  • SS 316 Tubes Wall thickness is expressed in millimeter, or inches, or BWG, SWG

Metline is one of the largest and most renowned manufacturing and stockholding company in India, supplying stainless steel 316L tubes as well as stainless steel 316L tube fittings and stainless steel 316L flanges. Given our extensive expertise and knowledge in stainless steel industry we can offer stainless steel 316L tubes, at the most competitive prices in the Industry. We are a wholesaler for stainless, acid and heat-resistant steel pipes, fittings and flanges with extensive stocks.

Stainless Steel 316 is the standard molybdenum-bearing grade, second in importance to SS 304 amongst the austenitic stainless steels. The molybdenum gives SS 316 better overall corrosion resistant properties than Stainless Steel 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. Stainless Steel 316 has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. SS 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections. SS 316L, the low carbon version of SS 316 and is immune from sensitisation (grain boundary carbide precipitation).SS 316H, with its higher carbon content has application at elevated temperatures, same as SS 316Ti which is a Titanium stabilised grade .SS 316N is nitrogen enhanced with greater strength than SS 316.

Both SS316 and SS316L have exceptional resistance to corrosion against sulfuric, hydrochloric, acetic, formic, and tartaric acids; as well as against acid sulfates and alkaline chlorides. They are widely used in exhaust manifolds, heat exchangers, pharmaceutical equipment, cryogenic piping, valve and pump trims, chemical & petrochemical process, pulp and paper industry, and food industry, etc.

Heat Resistance of Stainless Steel 316/316L Tubes

Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important.

Heat Treatment of Stainless Steel 316/316L Tubes

Solution Treatment (Annealing) Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.

Welding of SS 316/316L Tubes

Excellent weldability by all standard fusion methods, both with and without filler metals.
