Why Hot Hardness? Phenomena such as phase transformation and change in solubility of alloys could significantly alter the mechanical properties of the components used in high temperature applications. As the temperature of the material increases, its hardness generally decreases until it reaches a point where it shows a drastic reduction in hardness. Thus for accurate engineering calculations, such as component life and wear protection, it is imperative to measure the hardness of materials at the temperatures experienced during its use.

Rtec Solution – Perform hot hardness testing at elevated temperature up to 1000 °C. To prevent oxidation of tip and the samples, the chamber comes with optional inert gas sealed chamber. Mounts on our MFT-5000 platform. Motorized XY stages allow arrays of indents on same or across multiple samples.
