This study
evaluated the performance of five different grades of steel, including
conventional mild steel, conventional High Strength Steel (HSS), and
several grades of advanced HSS. This study features DP590Y, an
advanced HSS composed of ferrite-martensite phases, a new product jointly
developed and produced by U. S. Steel and Kobe Steel. The purpose of
the study was to determine the
material properties, forming characteristics, springback characteristics,
stamping failure, and crash energy management criteria for each
grade.
The figure below shows the results of each test. The
material with the best performance is represented by 1.0; each material
follows according to the percentage of its result against the leading material. To
view the results of each test, please click on the test name in the figure, or use the navigation bar
on the left of the screen.
Advanced
grades of HSS show improved formability over the conventional grades of
HSS, these have limited ductility. These advanced grades of HSS expand the
opportunities to design efficient complex components while providing
improved in-component material strength. This also provides the
opportunity to improve the components stiffness, strength, durability, and
crash energy management while reducing overall weight of the vehicle.
Automotive
components designed with advanced HSS grades requires a shift in design
approach from that used with conventional HSS grades to gain the greatest
weight reduction potential.
