Mechanical properties of high purity Fe-26 Cr-1 Mo ferritic stainless steel

The physical metallurgical characteristics of high purity Fe-26 Cr and Fe-26 Cr-1 Mo ferritic stainless steels, containing low carbon and nitrogen contents, were studied. The studies demonstrate that a commercially produced Fe-26 Cr-1 Mo high purity alloy containing a maximum of 50 to 150 ppm of carbon and nitrogen is capable of good mechanical properties and fabricability. The alloy was previously demonstrated to exhibit good corrosion resistance. Because of these properties, the high purity Fe-26 Cr-1 Mo alloy is a viable alternate to 300-series stainless steels as well as more highly alloyed materials for many applications. This paper is based on a presentation made at a symposium on “New Developments in Ferritic and Duplex Stainless Steels,” held at the Fall Meeting in Cleveland, Ohio, on October 19, 1972, under the sponsorship of the Corrosion Resistant Metals Committee of TMS-IMD and the Corrosion and Oxidation Activity of the ASM.
