Because of their inhomogeneous structure, sprayed claddings applied with this stainless steel wire do not exhibit the same chemical resistance as do steels of the same composition. Claddings of this kind can therefore be designated only as rust- and corrosion-inert. Corresponds to base metal 1.4301; hardness: about 250 HB.
