SS 347 Angle earns its place on high-temperature structural drawings because niobium locks up the carbon before chromium can, so the weld-affected zone stays free of the corrosion-prone carbides that weaken ordinary 304/316 sections after fabrication. That single difference is why UNS S34700 equal and unequal leg angle keeps its strength and surface integrity through repeated welding, post-weld cooling and continuous service up to 870°C — conditions that would sensitize a standard austenitic angle within hours. Buyers specify this grade for pipe-rack bracing, furnace framing and exhaust structures precisely because it can be cut, welded and re-welded on site without a mandatory post-weld heat treatment step, saving both fabrication time and project cost.

How To Verify Genuine WNR 1.4550 Channel Before Payment
Ask For Mill Test Certificate
Match the heat number on the MTC to the physical stamp on the angle.
Request A PMI Test
Positive Material Identification confirms actual Cr-Ni-Nb content on site.
Check The IGC Test Report
ASTM A262 report confirms the batch is free from intergranular corrosion risk.
Book Third-Party Inspection
Call in SGS, BV or TUV for a pre-shipment check before the container is sealed.

Frequently Asked Questions
What is the difference between SS 347 and SS 321 Angle?
SS 347 is stabilized with Niobium while SS 321 uses Titanium. 347 handles higher temperature exposure and repeated welding better than 321.
Is SS 347 Angle suitable for outdoor marine structures?
Yes. Its chromium-nickel content resists chloride attack, making it suitable for coastal and marine structural framing.
Can SS 347 Angle be welded without post-weld heat treatment?
Yes, its low carbon plus niobium stabilization prevents chromium carbide precipitation, so PWHT is generally not required.
What is the minimum order quantity for export?
Standard MOQ is 500 Kg per size; consolidated LCL shipments are available below this quantity on request.
Do you supply mill test certificates with every shipment?
Yes, EN 10204 3.1 is standard; 3.2 third-party certification is available for an additional cost and lead time.
