An electric car manufacturer is
looking to utilize some stock AISI
8740, hot rolled steel bars that are
around 2 inches in diameter for
their conveyor system that is being
set up to start producing their own
batteries. The data sheet shows the
the bars to have 132,000 psi
tensile strength, 87,500 psi yield
strength, and 16.7% elongation. A
hardness of 262 Bhn allows it to be
finish machined after heat
treatment. They keep their
workspace at 70°F.
What is the surface reduction
factor?
