ASK:
ANSWER:DX57D is a steel grade in European standard,DX57D is special deep drawing quality steel material, The material No. of DX57D is 1.0853.
DX57D's Carbon composition content is less than 0.12%, it belongs to low carbon material, used for cold forming.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So DX57D+Z means hot dip zinc coated, low carbon for cold forming, Super deep drawing , Flat product steel.
DX57D+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
DX57D+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
DX57D+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
DX57D+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
DX57D+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
DX57D+Z steel mechanical property:
Yield strength should be between 120-170MPa
Tensile strength should be between 260-350MPa
Elongation A80 should be not less than 41%
Plastic strain ratio R90 should be not less than 2.1
Strain hardening exponent N90 should be not less than 0.22
