Abstract
13%-Cr martensitic stainless steels are widely used in the production of many mechanical components that require high hardness and good corrosion resistance. In the present work, 20mm-diameter 13Cr-2Ni-2Mo steel bars were quenched by induction heating (IH) method and after that tempered in a farness. 240 hours corrosion test of the bars was carried out using a salt spray testing method (JIS Z 2371:2000). The results were compared to two stainless steels, SUS304 and SUS440C. Their inner hardness distributions were measured. It was found that the hardness of IH-quenched and farness-tempered 13Cr-2Ni-2Mo stainless steel is almost the same as that of the SUS440C. The 13Cr-2Ni-2Mo steel has the same corrosion resistance as the SUS304 steel.
