UNS N02201/N4 (Nickel 201)
Material grades and equivalents UNS N02201/ W.Nr 2.4061/N4/DIN 2.4068
UNS N02201/N4 (Nickel 201) alloy is a commercially pure wrought alloy having properties similar to that of nickel 200 alloy, but with a lower carbon content to avoid embrittlement by inter-granular carbon at high temperatures. It is resistant to acids and alkalis, and dry gases at room temperature.
