Nimonic 90 (UNS N07090) contains 15–21% cobalt and is among the strongest grades in the Nimonic series, retaining creep and oxidation resistance to 920 °C in turbine blades, high-temperature springs and fasteners.
As a manufacturer and global exporter of special alloys since 2012, Shanghai Hangbo Alloy Group Co., Ltd. supplies Nimonic 90 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings — all with EN 10204 3.1 certified material test reports.

Frequently asked questions
What heat treatment does Nimonic 90 use?
A typical cycle is solution treatment at 1080 °C for 8 hours, air cool, then ageing at 700 °C for 16 hours and air cooling. For spring applications a cold-draw plus ageing combination can raise strength further.
What forms and sizes are available?
We supply Nimonic 90 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), forgings & rolled rings (up to 7500 kg, 3500 mm OD), machined parts to your drawings. Custom lengths, tolerances and machining to drawing are available on request.
What is the MOQ and lead time?
MOQ is flexible — trial orders from a single piece are welcome. Stock sizes ship in 3–7 days; custom forgings and machined parts typically 15–35 days depending on quantity and process.
Can you provide third-party inspection and shipping to my port?
Yes. SGS / BV / TUV or your nominated inspector can witness all tests before shipment. Full export documentation is provided, and we ship worldwide by sea or air on FOB, CIF or DDP terms.
