Description

This is the simplest and most economical device for detecting hardness according to Brinell and determining tensile strength of engineering and tool steels, dies, forgings, railway material, beams, sheets, pipes, cast steel and various parts of steel as well as determining hardness according to Brinell for cast bronze, aluminum, brass, copper, grey and chilled cast iron.

Delivery Includes

Wooden case
Standard bar
Magnifying glass
Hardness conversion table

Technical Data

When the common POLDI hardness tester uses the check test piece made of steel having the strength of 70 kg/mm², the deviation of the tensile strength converted from the Brinell hardness compared to the real tensile strength in case of steel having the strength of 50-100 kg/mm² is maximum + 3 °/o , in case of milder types of iron and steel and steel having the strength of 100-150 kg/mm² (e.g. with hardened, heat treated and high alloyed steels) it is maximum + 5 °/o. With the stength of 150 – 200 kg/mm², inaccuracy may be, under certain conditions, even a little higher.
