Product Overview
The PowerRing-F22 is a high-performance ferritic-martensitic forged ring engineered for extreme-pressure and high-temperature service in mission-critical industries. Manufactured to ASME SA-182 Gr.F22 specification, this precision ring delivers exceptional creep resistance, thermal stability, and mechanical integrity — making it a preferred choice among aerospace rings suppliers and nuclear component fabricators. With dimensions of OD 950mm × ID 550mm × H 150mm, the ring is fully heat-treated (normalized and tempered) to optimize microstructure uniformity and dimensional stability. Its seamless, isotropic grain flow ensures superior fatigue life and structural reliability under cyclic loading.
Each PowerRing-F22 undergoes rigorous non-destructive evaluation (NDE) per ASTM E164 and ASME BPVC Section V, achieving UT Level 3 certification — the highest standard for ultrasonic inspection in critical rotating and pressure-bound components. This guarantees full volumetric soundness with zero internal discontinuities, voids, or inclusions exceeding acceptance criteria.
Key Features
- Ferritic-martensitic alloy optimized for elevated-temperature strength and oxidation resistance
- ASME SA-182 Grade F22 compliant — traceable to certified mill test reports (MTRs)
- UT Level 3 certified via 100% volumetric ultrasonic scanning (dual-element probes, pulse-echo & TOFD)
- Custom forgings with controlled grain refinement and minimal residual stress
- Surface finish: Machined-ready (Ra ≤ 3.2 µm), with optional shot peening or stress-relieving

Applications
The PowerRing-F22 serves demanding applications across aerospace rings systems (e.g., turbine casings, thrust reverser mounts), nuclear power plant components (reactor vessel closures, steam generator supports), petrochemical reactor internals, and heavy-duty industrial compressors. Its ASME SA-182 ring compliance and UT Level 3 certification make it ideal for ASME Section III Div. 1 & Div. 3 Class 1 components, where safety margins, long-term integrity, and regulatory traceability are non-negotiable.
