Description
SS 316 (1.4401) / SS 316L (1.4404) Seamless Pipes & Tubes Jindal with MTC 3.1
SS 316 / 316L Seamless Pipe is molybdenum bearing austenitic stainless steel. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304, especially with regard to pitting and crevice corrosion in chloride environments. In addition, SS316 / SS316L provides excellent elevated temperature tensile, creep and stress-rupture strengths, as well as outstanding formability and weldability. 316L is the lower carbon version of 316 and is immune from sensitization; therefore, it is very frequently used in heavy gauge welded components.
SS 316 / 316L Seamless Pipe is stocked by us from reputed Indian Mill like JSW, Jindal, Tubacex etc which are Approved under EIL, RIL, L&T, IOCL, BPCL, NPCIL, NTPC, TOYO ENGG, Major Industries in Nuclear, Refinery, Power as well as Major EPC’s and also some international approvals.
This Seamless Pipes comes as Dual Certified which is acceptable under both 316 & 316L Grades.
Size Range :
- • 1/2″ NB to 6″ NB x Sch 10s / 40s / 80s / 160.

Applications of SS 316 / 316L Seamless Pipes & Tubes :
- • Marine and Coastal Environments
- • Chemical processing, equipment
- • Laboratory benches and equipment
- • Rubber, plastics, pulp & paper machinery
- • Boat fittings, value and pump trim
- • Heat exchangers
- • Condensers, evaporators and tanks
Corrosion Resistance :
- • Generally more resistant than 304 in range of atmospheric environments and many corrosive media due to the increased chromium and molybdenum content.
- • Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 122°F (50°C).
- • Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at 140°F (60°C).
- • Usually regarded as the “marine grade stainless steel” – but is not resistant to warm sea water.
