Monel UNS N04400 Seamless Tube
Nickel alloy pipe of Nickel 201/UNS N02201/Alloy 201 Commercially pure (99.6%) wrought nickel essentially the same as Nickel 200 but with a lower carbon content to prevent embrittlement by intergranular carbon at temperatures over 600°F (315°C). Lower carbon content also reduces hardness, making Nickel 201 particularly suitable for cold-formed items.
