Manufacturing Process Of SS 321 Channel

Heat & Titanium Ratio Check

Every billet is verified against the Ti = 5(C+N) heat certificate first

Hot Rolling To Profile

Billets are rolled through calibrated passes into the final angle profile

Solution Annealing

Heated to 950-1120°C and water quenched to restore corrosion resistance

Stabilizing Treatment

Held at 870-900°C so titanium locks up carbon ahead of service welding

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

Welding Precautions & Common Defects In Stainless Steel 321 Angle

Use ER347 Filler, Not Titanium Rod

Titanium does not transfer well across an arc, so niobium-bearing ER347 is the standard consumable for 321.

Control Interpass Temperature

Keep interpass heat moderate to limit grain growth at the leg joint on thicker sections.

Watch For Knife-Line Attack

A narrow corrosion band can form beside the fusion line if reheated within the carbide range.

Avoid Titanium Carbide Inclusions

Excess heat input can precipitate TiC particles that weaken the weld deposit locally.

Purge The Root Pass

Back-purge with inert gas so the reverse side stays free of oxidation and sugaring.

Never Mark With A Graphite Pencil

Graphite raises surface carbon and can trigger cracking on later heat cycles near the mark.

Installation Guideline For SUS 321 Equal Leg Angle

Verify Heat & PMI Certificate On Site

Match the delivered certificate against the section before any cutting begins

Confirm ER347 Filler On Hand

Keep the matched consumable ready so site welds are not delayed

Align & Tack Before Final Weld

Check squareness and fit-up on the leg joint before running the full pass

Keep Carbon Steel Tools Away

Use dedicated stainless-only grinding discs and brushes to avoid iron contamination

Passivate Field Welds After Fit-Up

Re-passivate exposed joints once welding and grinding are complete

Inspect For Discoloration

Straw or blue heat tint near a joint signals a review before commissioning

Frequently Asked Questions

Is SS 321 Angle magnetic?

321 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 SS 321 angle?

Stainless steel angles, shapes and sections typically fall under HSN 7222.

What temperature can SS 321 angle withstand?

It resists scaling in intermittent service up to about 900°C and continuous service up to about 925°C.

Why is titanium added to SS 321?

Titanium locks up carbon so chromium carbides do not form at the grain boundaries during welding or hot service.

Can 321 be welded without post-weld heat treatment?

Yes, the stabilized chemistry generally removes the need for mandatory post-weld annealing on structural joints.
