Nickel 200/201
Documentation:
Description:
CM 200/201 is a commercially pure wrought nickel alloy. CM 201 was modified to control carbon (0.02 max) which keeps it from being embrittled by intergranular precipitates at temperatures of 600°F to 1400°F in many processes. The alloy is dual certified and has good mechanical properties with excellent resistance to many corrosive environments. It is widely used to handle caustic soda. Where product purity is a priority, CM 200/201 is especially useful.
