Abstract: A metal strip member (1) comprising a metal strip (2) having a thickness of less than 3 mm, and at least adjacent one side (3) consists of a substrate alloy with a chromium content of at least 10 wt %. The substrate alloy is on at least one side of the metal strip provided with a surface layer (4) of nickel, ruthenium, cobalt, palladium or an alloy thereof. Carbon and/or nitrogen atoms (5) are dissolved in the substrate alloy adjacent the surface layer providing compressive stresses, and essentially no carbides and/or nitrides are present in the substrate alloy. The invention also relates to resilient electrical contact spring member made of such a metal strip member and a method of manufacturing such a metal strip member.
