Since 1975, Proceq, a subsidiary of Paul Eagle, invented the Leeb hardness test principle, Equotip has become recognized worldwide as the industry standard in portable hardness testing. Different impact devices and a wide selection of test blocks and accessories are available to meet most application needs. In addition, Proceq has established conversion curves between Leeb hardness and other hardness scales and is widely applicable to various standards around the world.
Recently, the operating system of Equotip 550 has ushered in new upgrade. Latest version 2.9. One of the important updates of 0 is to integrate China’s power industry standard “DL-T1845 2018 Leeb Hardness Test Method for High Alloy Steel for Power Equipment” into the curve conversion material library of Equotip 550.
Equotip 550 series
DL-T1845 2018 specifies the Richter Hardness test principle and test procedure. Its normative appendix contains the hardness conversion of D-type impact devices HLD to HBW for several types of high alloy materials. Its design materials and corresponding applications are as follows:
These high-alloy materials are widely used in power plant pressure vessels, steam turbine facilities,Aircraft materials and other fields.
This upgrade enables power plant inspections to move away from Leeb hardness measurements for high alloy steel hardness values The dilemma that the result cannot be converted precisely. Previously, due to the lack of HLD and HBW conversion standards, the hardness test results of high-alloy steel products or components were somewhat unreliable, and the data results needed to be corrected before they could be used. The so-called correction is to establish the conversion curve of the two scales of HLD and HBW. Now, Equotip provides reliable HLD result values and excellent custom curve conversion methods. For inspectors or acceptance personnel, the built-in conversion curve of high alloy steel HLD to HBW that meets the standard requirements undoubtedly greatly simplifies the work process and improves work efficiency.

Other new upgrade highlights
Screeningeagle has been actively seeking localization solutions for Chinese customers. In addition to incorporating Chinese local standards into its own hardness scale conversion, this time, version 2.9.0 also provides a new remote control kit and new material curves from UCI.
Compared with the past, the new remote control kit enables both Rockwell and UCI probes to be automatically integrated, not limited to Leeb series probes. The measurement results can be directly connected to the software and database specified by the customer without going through the Equotip Link software for further processing and storage. The kit comes standard with command set documentation, dll dynamic link library and demo files, and a DemoRemote file for command testing.
andUCIIt has broken through the past only one based210GPaelastic modulus Material limitation. The available material range has been extended to difficult cast aluminum alloys,T/P91, cast steel, 304L Stainless steel and more. It should be noted that these conversion scales have a certain range, such as cast aluminum alloy conversionHV< span data-from-paste="1" data-diagnose-id="c7fd4cd2c6c539a7a0dc0344af5a55e5">The scale range is in 30to200HV. Especially for materials based on a fast moving conversion of one point in the table below, the results beyond the measurement range will lead to higher measurement errors.
