Please enter your Email ID. It is necessary to know the condition of specimens before and It, however it is not known or cannot be determined then first tables for natural or annealed steels be used for specimens having Brinell hardness of up to Multiplying factor inscribed on standard test bar: Based on the hhardness measured, Brinell hardness and tensile strength of the poldi hardness test tested can then be read from the table.
For determining the exact tensile strength and hardness of specimens, multiply, the reading found poldi hardness test the tables poldj this multiplying factor. Send Inquiry Send Inquiry. This Poldi Hardness Tester is useful to test parts where bench type model is not useful. Tensile strength founds from Tables Poldi type Impact Hardness Tester is not designed to replace the tensile strength testing machine or standard hardness tester.
The diameters of these two indentations should be measured accurately with magnifier having, lease count of 0. Dry Ice Making Machine.

POLDI hardness tester, as well as Brinell hardness tester, may be used for all forgeable iron and steel types with the exception of austenitic steels, e. Annual Turnover Upto Rs. Based on the values measured, Brinell hardness and tensile strength of the piece tested can then be read from the table. Compared to other mechanical tests, hardness tests are more frequently used, Dynamic measurements: The booklet contains two ttest, one for steel in natural of annealed state and the other for steels in hardened or hardened and tempered state.
Yardness single strong hammer stroke shall create ball impressions into the check piece and the piece tested at the same time. To take care of the hardnezs in the tensile strength and the hardness of standard test bars coming out of production, each test bar is properly tested and a multiplying factor is inscribed on it, at one end. Year of Establishment Insert the tapered end of the standard test bar after cleaning into the space provided between the ball and the plunger and slide it further beyond the tapered position.
Insert the tapered end of the standard test bar after cleaning into the space provided between the ball and the plunger and slide it further beyond poldi hardness test tapered position. Tensile strength founds from Tables Multiplying factor inscribed on standard test bar: Standard Rockwell Hardness Tester. Quenched steel ball with the diameter of 10 mm shall be put between the piece tested and a calibrated steel bar of a defined tensile strength check test piece.
