Hardness Testing

Hardness testing is used to determine the material's strength by measuring penetration resistance.

When performing this on in service equipment and parts, it is critical that testers know to adhere to procedures that are not destructive. Often in hardness testing in manufacturing, sample products are destroyed or damaged to determine the grade of metal. In production, the hardness testing will leave indentations that must not risk damage or reduce life expectancy.

Focus NDT is proficient in the use of standard testing tools and methods used for in service inspections. There is a method for selecting an appropriate hardness scale for examination of a specific part. The general guideline is to select the scale that specifies the largest load and the largest indenter possible. It is critical to do this without exceeding defined operation conditions and to account for other conditions that can influence test results.
