Complex-phase steel

Short name	VDA239-100*	Surface finish	Material number	Tensile strength R _p0,2MPa	Tensile strength R_mMPa	Elongation at break A₈₀²⁾% min.	Solidification exponent n_n10-UEmin.	Bake hardening index BH₂⁵⁾ min.
HCT600C	-	+ZE	1.0953	350-500	600	16	-	30
HCT780C	CR570Y780T-CP	+ZE	1.0954	570-720	780	10	-	30

_{1) XG = dual phase with increased yield strength}

_{2) Reduced minimum values of elongation at break apply to product thicknesses t < 0.60 mm (minus 2 units). * Comparative grade, therefore slight deviations from DIN EN values possible}

_{3) Elongation at break for a proportional sample with L0 = 5.65 √S0 for sheet thicknesses ≥ 3.0 mm}
