Nickel 201 (UNS N02201) is the low-carbon version of Nickel 200 (C ≤ 0.02%). It avoids grain-boundary graphitisation at elevated temperature, raising the service limit to 600 °C for high-temperature caustic and electronic applications.
As a manufacturer and global exporter of special alloys since 2012, Shanghai Hangbo Alloy Group Co., Ltd. supplies Nickel 201 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), precision strip (0.02–3.0 mm, ±0.005 mm tolerance), welding wire & coils (1.0–5.0 mm) — all with EN 10204 3.1 certified material test reports.

Frequently asked questions
Why is carbon limited in Nickel 201?
During long service above 315 °C, supersaturated carbon migrates to grain boundaries and precipitates as graphite, sharply reducing ductility and toughness. Holding carbon below 0.02% essentially removes this risk, allowing safe use up to 600 °C.
What forms and sizes are available?
We supply Nickel 201 as round bars (φ2–600 mm, up to 12 m), plates & sheets (0.5–100 mm thick, up to 2500 mm wide), seamless tubes & pipes (φ6–630 mm OD, 0.5–40 mm wall), precision strip (0.02–3.0 mm, ±0.005 mm tolerance), welding wire & coils (1.0–5.0 mm). 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.
