Characterization and Comparative Analysis of Corrosion Resistance of 4 High Manganese Steels Models in Aqueous Solution of NaCl

The liquefied natural gas volumes that currently need to be stored and/or transported require engineering to consistently develop materials that combine high mechanical strength and low manufacturing costs. The present work brings the study of four models of high manganese steels (non-commercials), to demonstrate the feasibility of being used in the petrochemical industry. The tests contemplate the characterization (composition, phase diagram, metallography, EBSD, microhardness), corrosion resistance in NaCl solution (Open Circuit Potential, Linear Polarization) and characterization of corrosi...
