Effects of Coloring Conditions on the Properties of the Film for Colored Stainless Steels

Synopsis : Colored films on the stainless steel, formed by the alternating current electrolyzing ( ACE) method and the conventional one ( INCO method) , have been studied to clarify the differences in the structure, rub resistance and polarization resistance of them. In the ACE method, the effects of electrolyzing patterns on the color tone and polarization resistance of the film have been inve...

Low-Temperature Carburization of Austenitic Stainless Steels

LOW-TEMPERATURE CARBURIZATION is a gaseous carburization process performed at atmospheric pressure, at temperatures where the kinetics of substitutional diffusion are very slow. Low-temperature carburization hardens the surface of austenitic stainless steels through the diffusion of interstitial carbon, without the formation of carbides. The surface must be activated, by modification and remova...

Development of Alumina-Forming Austenitic Stainless Steels

This paper presents the results of the continued development of creep-resistant, alumina-forming austenitic (AFA) stainless steel alloys, which exhibit a unique combination of excellent oxidation resistance via protective alumina (Al2O3) scale formation and high-temperature creep strength through the formation of stable nano-scale MC carbides and intermetallic precipitates. Efforts in fiscal ye...
