  O = No cracking
D = Deformation visible
X = Cracking
GS = Grain Size, TS = Tensile Strength,  YS = Yield Strength, EL = Elongation, HV = Hardness Vickers
In the bending test, samples are bent in relation to the material's rolled direction, across the rolled direction or in the rolled direction.
The above data are for material 0.2mm to 0.5mm in thickness
