Abstract (en)

[origin: WO8704731A1] A stainless steel having well balanced physical properties, including good corrosion resistance, intermediate strength and good machinability and further being readily processed and prepared at low cost. To achieve these properties the microstructure is primarily martensite and ferrite with a limited amount of austenite. Elemental compositional ranges are controlled along with the microstructure resulting in defining the approximate compositional/microstructural boundaries in terms of a region in a Schaeffler type Diagram.
