Effects of Corrosion on the Microstructure, Hardness, and Microhardness of ASTM A335 P92 Steel
Chemical Engineering Transactions, 2019 In the present work was evaluated the microstructure of ASTM A335 P92 steel when this material is exposed to two corrosive mixtures O2 - H2O, O2 - N2 - H2O. In addition, the hardness and microhardness of this steel were studied.
