General Characteristics
201/4618 is an austenitic stainless steel, which belongs to the austenitic low-nickel CrMn stainless steel family, in which manganese replaces part of the nickel that is normally alloyed to CrNi standard grades. This variant has low nitrogen content and copper alloying for improved forming properties.
Corrosion resistance of the austenitic CrMn grades is usually slightly below that of the austenitic CrNi standard grades. 201/4618 is used in applications where good formability and corrosion resistance are needed.
