Effects of Initial Material Conditions on the High Temperature Surface Oxidation of Press-hardening Steels Biao Deng1,a, Hongliang Yi1,b,* School of Materials and Metallurgy, Northeastern University, Shenyang 110000, China adengbwel@163.com, b,* hityihl@126.com Keywords：22MnB5 steel; cold rolling; annealing; surface oxidation 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.
Hot stamping steel mainly has the non-plating materials and Al-Si plating materials, Al-Si plating layer can effectively prevent surface oxidation of the material in the hot stamping process, but the cost of production is high; non-plating material will be some oxided inevitably during hot stamping, the surface oxide layer is removed by blasting method after hot stamping, the cost is low, therefore, the non-plated material has a large practical applications.
Surface oxidation behavior of non-plated material can reduce the mechanical performance and stability of parts [2], how to reduce the surface oxidation behavior of non-plating material is still a serious problem.
Experiment methods Pickling sheet treatment: pickling 22MnB5 material after removing decarbonization layer and oxide layer, the thickness of pickling sheet is 1.3mm; cold-rolled sheet treatment: cold rolling on the basis of pickling sheet, cold rolling to 1.1mm; cold-rolled annealed sheet treatment: annealing on the basis of cold-rolled sheet, steel specimens are kept warm at 700℃ and with 10min holding time, and then furnace cool to room temperature. 22MnB5 steels with three early treatment (pickling, cold rolling, cold-rolled annealing) were heated at high temperature, heating process was shown in the Fig 1, under 930℃, and with 5min holding time, and then air cool to room temperature.

Among many available models of anisotropic materials for plane state of stress and strains, the most frequently used are Hill’s [1], Barlat, Lian’s [2], Banabaic et al. [3].
The material constants (Young's modulus E, Poisson's ratio ν) assigned to type 20 material do not cause its elastic properties.
