A cut disc is a solid circular piece cut from flat plate stock, primarily used for flat caps or vessel heads. A seamless forged ring is a hollow ring produced via ring rolling, creating a continuous grain flow along the circumference for high-pressure mechanical applications.
Yes, we supply solid discs, blind flange blanks, and circles with custom inner diameter (ID) cutouts or bolt-hole patterns per project drawings.
For elevated temperatures up to 1150°C, we supply SS 310/310S, Inconel 600/625, and Hastelloy X rings and circles.
We supply cut circles with smooth laser-cut edges, waterjet-milled edges, smooth-turned CNC machined finishes, or weld-ready outer edge bevels based on project requirements.
Yes, every shipment processed by Nirvaan Overseas is accompanied by EN 10204 3.1 Material Test Certificates detailing heat numbers, chemical spectro analysis, UT reports, and mechanical test results.
