DC52D + AZ steel sheet mechanical property :

STEEL GRADE	Tensile Strength (Mpa)	Yield Strength (Mpa)	n90	r90	Elongation% min (Lo=80mm b=20mm)		The coating adhesion (The heart bending diameter )
			min	min	0.7mm	0.7mm	140/140	140/140-175/175	175/175
DC52D + AZ	270-420	140-300	-	-	24	26	0a	1a	2a

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.
