Impex Tube India, a renowned Mumbai, India-based manufacturer and supplier, deals in a comprehensive array of high-quality stainless steel products catering to industrial needs. Out of their best products, Stainless Steel 316 and 316L Welded Tubing are notable due to their superior corrosion resistance, high strength, and excellent weldability. Such welded tubes find ideal application where chemicals, moisture, and chlorides are present. Impex Tube India provides critical industries like pharmaceuticals, petrochemicals, marine, and food processing with Stainless Steel 316/316L welded tubing solutions that provide endurance, performance, and compliance with international quality standards.
Stainless Steel 316 and 316L Welded Tubes are austenitic stainless steels with contents of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%) for improvement of corrosion resistance, particularly in environments with high chloride. The only distinguishing factor is in carbon content—316L has a maximum of 0.03% to avoid carbide precipitation during the welding process. The two grades have superior mechanical properties with tensile strength of 485–620 MPa and yield strength of 170–310 MPa. These welded tubes are ductile and tough, providing consistent performance in high-temperature and low-temperature conditions, as well as corrosive and pressure conditions.

Stainless Steel 316 and 316L Welded Tubing is used extensively in industries where there is a need for high corrosion, pressure, and temperature resistance. In chemical and petrochemical industries, the tubes are utilized for carrying acids, solvents, and other corrosive materials. Pharmaceutical and food processing industries appreciate the use of 316/316L tubing due to its sanitary finish, ease of cleanliness, and resistance to contamination. In aquatic environments, the tubing is resistant to crevice corrosion and pitting, thus finding applications in seawater. Moreover, the tubes are utilized in heat exchangers, instrumentation, architectural structures, and structural parts. 316L is particularly found to be most useful in welded structures that need corrosion resistance without post-weld heat treatment.
