of the corrosion property of Cr4Mo4V bearing steel using plasma. These improvements are attributed to redistribution of nitrogen and formation of a thin oxide layer on the sample due to annealing. 440C Stainless Steel:Properties, Processing and 440c steel has moderate corrosion resistance when compared to other stainless steels, and it exhibits its best corrosion resistance in its hardened and tempered form. However, care must be taken to avoid over-tempering, which results in a decline in its corrosion resistance. Table 1. Properties of annealed 440c stainless steel

acid concentrations above about 5%, C-276 alloy provides a quantum improvement over the stainless steels, and offers much greater resistance to higher concentrations of both acids than alloy 625. The concentration limit of 20% hydrochloric acid is the azeotrope, beyond which high temperature corrosion tests are less reliable. Improved in vitro corrosion resistance of a NiTi alloy by The mechanical property and corrosion resistance of irradiated samples were examined. It was observed that, after HCPEB irradiation, a melting layer with depth of about 4 m was formed on the Improvement of the corrosion and tribological properties Jan 15, 2017 · The corrosion and tribological properties of an aerospace bearing steel CSS-42L was investigated. Carbon ion implantation was conducted and an amorphous layer formed at the near surface of CSS-42L steel. The enhanced Cr diffusion and the decreased free electrons are contributed to the improvement of corrosion properties.
