Hardness testing enables you to evaluate the strength, ductility and wear resistance of a material, which can determine whether a material is suitable for the purpose you require.

Poldi Hardness Testing

Poldi Hammer is a simple and economical device for defining hardness and determining the tensile strength of engineering and tool steels, dies, forgings, railway material, beams, sheets and pipes. Also, cast steel and various parts of steel, cast bronze, aluminium, brass, copper, grey and chilled cast iron are where we use it.

A hammer helps POLDI hardness testers to perform the impact test at the assembly sites. A quenched steel ball is placed with a diameter of approx 10 mm and a length of 85mm between the piece tested and a calibrated steel bar. Later, a single firm hammer stroke creates ball impressions on the piece. Diameters are measured using a magnifier to test the strength.

Digital Hardness Testing

Digital hardness testing helps evaluate a material’s properties, such as strength, flexibility and wear resistance. Impartial Testing applies to determine whether a material or material treatment is suitable for the purpose you require. It helps to find the resistance a material exhibits to permanent deformation by penetrating another more complex material.

Digital Hardness Testing lets the inspector perform in-situ hardness measurements, thus offering quick and economical supplements to conventional, stationary testing machines. In this process, we press a specifically dimensioned object (indenter) into the material’s surface. The depth of indenter penetration or the size of the impression states the hardness.
