SS 316 Connector exporter in India
Last Updated: July 2026
Quick Answer
SS 316 Connector is a molybdenum-alloyed double-ferrule compression fitting that joins stainless steel tubing to a threaded NPT or BSP port for chloride-resistant service. Manufactured to ASTM A479 and ASME B31.3.
SS 316 Connector exporter in India joins stainless steel instrumentation tubing directly to a threaded port using double-ferrule compression technology, built for installations exposed to chlorides, saline air, or aggressive chemical media where standard 304 connectors fall short.
Manufactured from SS 316 austenitic stainless steel with 2-3% molybdenum added to 16-18% chromium and 10-14% nickel, these connectors resist pitting and crevice corrosion in chloride-rich environments significantly better than 304, while still delivering the same metal-to-metal double-ferrule seal without welding.
Available as male, female, union, bulkhead, and reducing connectors, manufactured to ASTM A479 and ASME B31.3, and dimensionally compatible with standard double-ferrule tube fitting systems – making it straightforward to upgrade an existing 304 installation to 316 where corrosion performance needs improving.
As the manufacturing origin, India offers buyers direct factory access, shorter lead times, and pricing without an intermediary trading markup.
Sourcing SS 316 Connector directly from an Indian manufacturer gives domestic buyers faster turnaround and full visibility into raw material and inspection records.

Manufacturing Process & Heat Treatment of SS 316 Connector
Annealing
Connector bodies are machined from solution-annealed SS 316 bar stock (annealed at 1040°C to 1120°C) to fully dissolve carbides and preserve the molybdenum-bearing matrix's chloride resistance before ferrule assembly.
Forging
Connector bodies and hex nuts are forged from SS 316 bar stock at 1100°C to 1230°C, with tighter temperature control than 304 to avoid carbide precipitation that would reduce corrosion resistance at the ferrule-bearing surfaces.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040 - 1120 | Water | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Relieve residual stresses from machining |
Controlled annealing preserves the molybdenum-bearing austenite structure that gives SS 316 connectors their chloride and pitting-corrosion resistance in export shipments.
