Effect of Batch-Annealing Temperature on Oxidation of 22MnB5 Steel during Austenitizing

open access: yesMetals, 2023
In this paper, the effect of batch-annealing temperature on the oxidation of 22MnB5 steel during austenitizing was studied. When the batch-annealing temperature was decreased from 690 to 680 °C, the surface roughness of cold-rolled 22MnB5 steel decreased,
