Effects of Initial Material Conditions on the High Temperature Surface Oxidation of Press-Hardening Steels

Abstract:

The 22MnB5 steel of Wuhan Iron with three early treatment (pickling, cold-rolling and cold-rolled annealing), then high-temperature oxidation, surface morphology and element of the oxide layer were observed after oxidation testing. The result shows that the oxide layer thickness of cold-rolled annealed sheet is maximal, followed by cold rolled sheet, the pickling sheet is minimum; The surface roughness is associated with degree of oxidation; Si and Cr content increase sharply in oxide layer of 22MnB5 steel after annealing, annealing and cold rolling have little effect of Mn content in the oxide layer.
