A Design Study in Centrifugal Steel Castings - Accumulator Cylinder                                  

 Accumulator Cylinder -- Requirements

The performance requirements for the cylinder are:

Mechanical Properties-- 

-- Ultimate Tensile Strength = 110 KSI

-- Yield Strength = 70 KSI

-- Elongation/Strain to Fracture = 20%

-- Fracture Toughness = 35 Ft. Lbs by Charpy Impact

-- Hardness = 229-250 Brinell 

As-cast Tolerances (OD, Length) = ± 1/16"

The quality assurance process includes complete inspection of each casting per military specifications by liquid penetrant and radiographic testing.
