Ganpat Industrial Corporation has served Indian and export piping buyers since 1997. Stainless Steel 304L Buttweld Fittings carry a low carbon core. This keeps the weld zone free of chromium carbide precipitation. It means no post-weld annealing is needed. We supply ASTM A403 WP304L Elbows, Tees, Reducers, Caps and Stub Ends. Every fitting is dimensioned to ASME B16.9 and ASME B16.28. We machine, bevel and test each batch at our Mumbai facility. This makes us a reliable Stainless Steel 304L Pipe Fittings source. Every despatch carries an EN 10204 3.1 mill test certificate. We regularly supply this range to Vadodara, Chennai and Kandla. We also export to Dubai, Jebel Ali, Rotterdam and Houston.

SS 304L vs SS 316L Buttweld Fittings
Buyers often compare 304L with 316L. We get asked this on almost every enquiry.
SS 316L Buttweld Fittings
- Molybdenum-bearing, marine grade
- Better chloride and pitting resistance
- Higher cost than 304L
- Preferred for seawater and chemical duty
Stainless Steel 304L Buttweld Fittings
- No molybdenum, lower material cost
- Strong general atmospheric corrosion resistance
- Ideal for food, dairy and water lines
- Widely stocked, shorter lead time
Standard 304 Buttweld Fittings
- Higher carbon, up to 0.08%
- Needs post-weld annealing on thick sections
- Risk of weld-zone carbide precipitation
- Lower cost than 304L
Stainless Steel 304L Buttweld Fittings
- Carbon capped at 0.030% max
- No post-weld annealing required
- Resists intergranular corrosion after welding
- Preferred for heavy gauge welded fabrication

Stainless Steel 304L Buttweld Fittings Frequently Asked Questions
What is the difference between 304 and 304L fittings?
304L carries lower carbon, so it skips post-weld annealing entirely.
What is the UNS number for SS 304L Buttweld Fittings?
UNS S30403, also shown as Werkstoff Nr. 1.4306 or 1.4307.
Is ASTM A403 WP304L suitable for seawater service?
Not ideal. SS 316L handles chloride and seawater duty better.
What sizes are available in ASME B16.9 fittings?
½ inch to 48 inch, seamless up to 24 inch NB.
What is the HSN code for SS 304L Buttweld Fittings?
HSN 7307, taxed at 18% GST in India.
