Effect of manufacturing process sequence on the corrosion

Jan 15, 2014 · Corrosion tests. Manufactured BPPs were exposed to corrosive environment to assess their corrosion resistance. Two commonly referred electrochemical corrosion test methods in literature [11], [36], [39], [43], [44] namely potentiodynamic (PD) and potentiostatic (PS) tests, were exploited in this investigation. Patent Report:US9863015 Manufacturing method for A manufacturing method for strip casting 550 MPa-grade high strength atmospheric corrosion-resistant steel strip, comprising the following steps:1) smelting, where the chemical composition of a molten steel is that:C is between 0.03-0.08%, Si0.4%, Mn is Steel additive manufacturing:a study on corrosion resistanceAug 14, 2019 · For the study of microstructure and corrosion resistance, the samples were then subjected to metallographic and electrochemical characterization, respectively, the first through Scanning Electron Microscopy (SEM), Fluorescence X-ray Spectroscopy and Optical Bright Field Microscopy (LOM-BF), the second by means of Potentiometric Analysis is Electrochemical Impedance

CN1044388C - Method of manufacturing stainless steel

This invention relates to a process for the production of stainless steel sheets having a more excellent corrosion resistance as compared with the conventional one without trimming the steel sheet surface after annealing-pickling by preventing the chapping of steel sheet surface created in the production of present stainless steel sheet, particularly stainless steel sheets having extreme-low amounts of C, S, O.
