Every shipment dispatched by Nirvaan Overseas—a dedicated SS 304 Rings & Circles Supplier—undergoes structured quality verification:
| Inspection Method | Evaluation Parameters |
|---|---|
| Dimensional Inspection | Vernier calipers, micrometers, and 3D coordinate checking to verify outer diameter (up to 2000 mm), inner diameter, and thickness. |
| Ultrasonic Testing (UT) | Non-destructive scanning per ASTM A388 / EN 10228 to detect internal inclusions or plate laminations in thick cut blanks. |
| Chemical Analysis & PMI | Handheld Spectro PMI testing to verify low-carbon limits for 304L (0.03% max) versus standard 304 (0.08% max). |
| Certification | Mill Test Certificates per EN 10204 3.1, heat traceability, and optional Third-Party Inspection (TPI). |
A: Choose SS 304L (UNS S30403) if the rings or circles will be welded during vessel assembly. Its lower carbon content (0.03% max) prevents intergranular corrosion in the weld heat-affected zone.
A: As a direct SS 304 Rings & Circles Supplier, we produce custom-cut circles and forged rings up to 2000 mm in outer diameter.
A: Yes, we supply both solid SS 304 Circle Blanks and concentric SS 304 Ring Blanks with precise CNC-machined inner (ID) and outer (OD) dimensions.
A: We process plate-cut discs and forged rings in thicknesses ranging from 1 mm up to 100 mm.
A: Yes, as an established SS 304 Rings & Circles Exporter, every dispatch includes EN 10204 3.1 MTCs with full chemical, mechanical, and PMI test data.
