A Design Study in Centrifugal Steel Castings -
Accumulator Cylinder
Duplex
Alloy
Selection
The
duplex stainless steel alloy of choice for this casting is ASTM A-890,
which is available in seven different grades.
Given
the mechanical property requirements for the accumulator, consider the nominal
properties of three A-890 grades in the table below and
choose the grade that best meets the mechanical requirements.
