Ganpat Industrial Corporation supplies Stainless Steel 307 Wire from Mumbai and has
served industrial buyers since 1997. SS 307 Wire is an austenitic grade alloyed with 3.3 to 4.75% manganese. It
cannot be hardened by heat treatment, forms and draws easily, and stays tough down to cryogenic temperatures.
Welders choose it to join stainless steel to carbon or low alloy steel and to repair hard-to-weld steels. We stock
SS 307L Wires with low carbon and 307H SS Wires for high temperature duty. Supply covers Stainless Steel 307
Welding Wire, Stainless Steel 307 Wires in coil and spool, and Stainless Steel 307 Wire Rope. Every pack ships
with a mill test certificate, and a TPI report is available. Send your grade, diameter and form for a quick quote.

307 vs 309L vs 308L Guide
Match Stainless Steel 307 Wire to the joint, not just the base metal.
| Joint Or Job | Best Wire | Why | Form |
|---|---|---|---|
| Stainless to carbon or low alloy steel, high dilution | SS 307 Wire (ER307) | Manganese resists cracking in the mixed deposit | MIG, TIG, flux core |
| Hard-to-weld steels, armour plate, manganese steel repair | Stainless Steel 307 Welding Wire | Tough austenitic deposit absorbs stress | E307-16, flux core |
| Buffer or buttering layer before final passes | SS 307L Wires | Low carbon limits hard zones at the fusion line | TIG rod, MIG |
| Stainless to carbon steel, standard joint | 309L filler | Usual first choice when dilution is controlled | Ask us for 309L |
| Same-type 304 or 304L joint | 308L filler | Matches 304 chemistry | Ask us for 308L |
Choose 307 when
- Steels differ in type
- Dilution is high
- Base steel is hard to weld
- You repair manganese steel
Choose 309L instead when
- You join stainless to carbon steel
- Dilution is well controlled
- Joint sees corrosive service
- Code names 309L
Choose 308L instead when
- Both sides are 304 or 304L
- Joint needs matching colour
- Service is corrosive only
- No mixed steels involved
