By adding a small amount of Tin,
the FW series shows excellent corrosion resistance even in a saltwater environment
by adsorbing Tin chemical species on the surface.

EXCELLEN T

Hi gh w o rk a b i l ity
NSSC FW™ has the highest level of workability among the ferritic grades.
By selecting the appropriate process conditions,
it is possible to perform equivalent level of forming processing as of SUS304.
