Piston Rod Predictor is a tool developed to compare resistance to buckling between different steel
grades in piston rod applications. Most hydraulic cylinders are loaded in axial compression and the
relevant failure mode is buckling. Higher strength imparts better resistance to buckling and offers the
possibility to downsize rods, thereby reducing both weight and cost. Ovako manufactures a range of
hard-chrome-plated or Nickel-chrome-plated ready-to-use bars and tubes, known as Cromax. In the
Piston Rod Predictor, you can compare Cromax steel grades to most commonly used standard grades
used in piston rod applications.
