201 stainless steel coil is a lower-cost alternative to theconventional Cr-Ni austenitic stainless steels, such as 304 coil.
201 stainless steel coils have relatively lower ductility and formability compared to 301 stainless steel coil.
Grade 201 coil also has good welding characteristics and low temperature properties.
