a means when the thickness is more than 1.5mm, the minimum value r90 can lower 0.2.
b means when the thickness not more than 0.7mm, the minimum value r90 can lower 0.2, n90 can lower 0.01.
c means For difference thickness of coating products, thick coating surface as the outer surface of the bending test.
The material St06Z is the old grade for DC54D+Z and they are same for the chemical composition and mechanical property.
