Nickel 200 / Nickel 201 Round Bars
Nickel 200 is commercially pure (99.6 %) wrought nickel with good mechanical properties and excellent resistance to caustic alkalis, neutral and alkaline salts and many reducing chemicals. Nickel 201 is the low carbon version, which avoids graphite precipitation and embrittlement and is therefore specified for service above 315 °C, up to about 600 °C.
Nexforge Alloys supplies Nickel 200 and Nickel 201 round bars in the annealed, hot finished or cold drawn condition to ASTM B160 / ASME SB160. Bars are supplied with mill test certificates and can be cut to length or rough machined for fasteners, electrodes and process equipment.
Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201) round bars from 6 mm to 200 mm diameter, as per ASTM B160 / ASME SB160 and DIN 17752.
