Ganpat Industrial Corporation has supplied Indian and export piping buyers since 1997. SS 304 Threaded Fittings use a standard austenitic chemistry with wide market acceptance. They thread onto small bore pipe without any welding or heat input. We forge and machine Elbows, Tees, Crosses, Couplings, Unions and Bushings in-house. Every fitting is machined to ASME B16.11 in Class 2000, 3000 and 6000. Threads are cut to ASME B1.20.1 NPT on our own machining floor. This keeps us a dependable SS 304 Threaded Fittings source for repeat buyers. Every dispatch carries an EN 10204 3.1 mill test certificate as standard. We regularly supply this range to Rajkot, Jamnagar and Ankleshwar buyers. We also export to Dubai, Sharjah, Dammam and Houston on request.

SS 304 vs SS 316 vs SS 304L Threaded Fittings
Buyers often compare 304 with 316 and 304L. We field this on most enquiries.
SS 316 Threaded Fittings
- Molybdenum-bearing, marine grade
- Better chloride and pitting resistance
- Higher cost than 304
- Preferred for seawater and chemical duty
SS 304 Threaded Fittings
- No molybdenum, lower material cost
- Strong general atmospheric corrosion resistance
- Ideal for food, dairy and water lines
- Widely stocked, shorter lead time
SS 304L Threaded Fittings
- Carbon capped at 0.030% max
- Better weld-zone corrosion resistance
- Slightly lower strength than 304
- Preferred after heavy welding work
SS 304 Threaded Fittings
- Higher carbon, up to 0.08%
- Higher tensile and yield strength
- Threaded joints need no welding at all
- Standard, most economical stocked grade
