The essential role of non-destructive testing in evaluating stainless steels and corrosion resistant alloys – an interview with Ana Benz, Chief Engineer at IRISNDT

Nondestructive testing (NDT) or nondestructive evaluation (NDE) encompasses a wide group of analysis techniques to evaluate the properties of a material, component or system without causing any damage to the original material. Many industries, such as the oil & gas and petrochemical sectors benefit from having project materials, like stainless steel and corrosion resistant alloys […]

IRISNDT measures microhardness with a Vickers Pedestal Static machine. This is calibrated to UKAS standards and allows use of 10Kg and 30Kg loads for a broad range of material hardness values.

Hardness is measured by applying a diamond indenter to the material surface. This leaves a very small indent in the region of 0.3mm across the diagonals. Hardness values are obtained by dividing the indentation area by the load. The small indentation size means hardness values can be measured and profiled over localised areas such as weld heat affected zones.

Samples are prepared in our machine workshop to leave parallel surfaces. These are polished to a mirror finish and we have the ability to hot mount small samples to ensure no distortion occurs during testing. Pictures of test samples are included in the final report showing the indentation pattern specified in the applicable code.
