www.nipponsteel.comwhere about 30% is the austenite phase and the rest is the martensitic phase, could be acquired by applying a quenching and partitioning method to martensitic stainless steel. The mechanical properties of the quenching material and partitioning material, and stability of the retained austenite phase, were examined.

Another common dissimilar metal combina-tion involves the use of high-nickel alloys for weld repair of cast iron. Fe-55Ni welding elec-trodes are used to make weld deposits that can hold in solid solution many of the alloying ele-ments common to cast iron. Furthermore, weld

Variations in heat treatment can be selected to enhance one or more of these properties. Improved corrosion resistance, particularly resistance to sulfide stress corrosion, can be obtained
