DC54D+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
DC54D+ AZ	270-350	140-220	0.18	1.6	34	36	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.
