Estimation of Tensile Properties of Pressure Vessel Steel ...

Extraction of mechanical properties of in-service materials through small specimen test techniques has become attractive in the recent years. Of the available small specimen test techniques, automated ball indentation (ABI) and small punch test (SPT) methods have proved to be more promising. These test methods are basically non-destructive in nature and are proficient enough to …

IEC 60601 (Steel Ball Impact Test)

Jan 30, 2013. #1. Jan 30, 2013. #1. IEC 15.3.3 requires an impact test and most of my research indicate that it must be done by a 50g steel ball (IEC 60950-1). It is sufficient if I purchase an approved steel ball (and accurately apply and record the force needed for the test) or do I need to purchase a more sophisticated device.

How are bearing balls made? | Engineering360

Bearing balls are the component of a ball bearing that permit smooth, friction-free rotary motion. They are typically manufactured out of steel, but can also be made from other materials such as silicon nitride ceramic, plastic or even glass. Steel bearing balls are easily the most common ball material, with tens of millions produced annually.
