TRIP 780/800 Steels


TRIP steel 780/800 is recommended for structural parts of high strength and complex geometry whenever requirements of very high formability in stamping are accompanied with a need for high crash energy management capacity.

Typical Mechanical Properties for TRIP 780/800

Product Yield Strength [MPa] Tensile Strength [MPa] Elongation [%] n-value 5%-UE True Stress/Strain Curve FLD Curve
HDGA 435 825 24 0.19 N/A N/A

Example of Stress/Strain Curve

Forming Limit Curve

Formability of 780/800T steel is much better than conventional HSLA or DUAL-TEN® steel of comparable strength level. Experimental FLC will be available in the future.

Bake Hardening

Response of 780/800T HDGA Steel to a Typical Paint Baking Cycle

Combined Effect of Work Hardening (WH) and Bake Hardening (BH)
for 780/800T HDGA Steel in a Typical Paint Baking Cycle

Yield strength of 780/800T HDGA steel increases more than 75 MPa after deformation to 2% and baking in a typical paint baking cycle.
