Equal Leg Vs Unequal Leg Angle – Which To Choose ?
Equal Leg Angle
- Both legs of identical width
- Balanced load in both axes
- Common for symmetric bracing & frames
- Easier to source in bulk stock lengths
Unequal Leg Angle
- One leg longer than the other
- Suits asymmetric or directional loading
- Preferred for platform edges & ledges
- Reduces material where full symmetry is not needed

Welding Precautions & Common Defects In SS 304L Angle
Use ER308L / ER316L Filler
Match a low-carbon filler wire so the weld metal keeps the same corrosion resistance.
Limit Heat Input
Control amperage and travel speed to avoid excess dilution at the leg joint.
Avoid Carbide Precipitation
Cool quickly through the 425-870°C sensitization range to prevent weld decay.
Watch For Intergranular Corrosion
A common defect where chromium carbides deplete the grain boundaries near the weld.
Purge The Root Pass
Back-purge with inert gas to stop oxidation and sugaring on the reverse side.
Clean Between Passes
Remove scale and flux residue to prevent slag inclusion defects in multi-pass welds.

Manufacturing Process Of SS 304L Channel
Billet Selection & Heat Check
Every billet is verified against the low-carbon 304L heat certificate first
Hot Rolling To Profile
Billets are rolled through calibrated passes into the final angle profile
Solution Annealing
Heated to 1040-1120°C and water quenched to restore corrosion resistance
Pickling & Passivation
Acid treatment removes scale and rebuilds the passive chromium oxide layer
Straightening, Cutting & PMI Check
Final straightening, saw-cutting to length and PMI check before dispatch
Documentation & Test Certificates Offered With INOX 304L U Channel
Mill Test Certificate 3.1
Chemistry & mechanical results traced to heat number

Frequently Asked Questions
Is SS 304L Angle magnetic?
304L is austenitic and largely non-magnetic in the annealed condition, though cold working can add slight magnetism at bends.
What is the HSN code for stainless steel angle?
Stainless steel angles, shapes and sections typically fall under HSN 7222.
Does 304L Angle require post-weld heat treatment?
No, the low-carbon chemistry generally does not require mandatory post-weld annealing for most structural sections.
Can 304L Angle be supplied in unequal leg sizes?
Yes, we stock and roll both equal leg and unequal leg 304L angle profiles.
What is the difference between 304L Angle and 316L Angle?
316L adds molybdenum for stronger resistance to chlorides and marine or acidic exposure compared with 304L.
