The DiaMet hardness testing software upgrade is now available for legacy Wilson testers. DiaMet can integrate and transform legacy testers to improve quality management using the software’s database.
The microstructure of a material represents its fundamental properties, and most heat treatments are performed to tailor these properties to a specific need. Good metallographic preparation allows faster and more-accurate quality control – whether a microstructural inspection or performing specific tests such as case-depth analysis.
The Buehler Wilson Reference Block Laboratory in Binghamton, N.Y., achieved accreditation to ISO/IEC 17025 by A2LA (American Association for Laboratory Accreditation) for Rockwell, Knoop, Vickers and Brinell hardness-testing blocks and indenters. A2LA is in full conformance with the standards of the International Organization for Standardization (ISO) and the International Electro-Technical Commission (IEC), including ISO/IEC 17025. Buehler markets the reference blocks along with the Wilson hardness testers and DiaMet software globally.
Rockwell hardness testing is one of the seemingly easiest tests to perform on the shop floor, in the quality-control department or in the metallurgical laboratory but arguably one of the hardest tests to perform properly. Let's learn more.
Hardness testing machines are configured for automated testing in production lines. Standardized Rockwell or Super Rockwell testing methods can be selected, and the test load range is between 15-150 kg.
The Verder Group acquired the majority of Austria’s Qness GmbH, a manufacturer of hardness testing machines that comply with recognized standards like Brinell, Vickers, Knoop and Rockwell. The acquisition extends the portfolio of Verder Scientific with a product line for hardness testing. Instruments manufactured by Qness are used both for industrial applications and material research.
This article provides actual data for testing performed to compare argon and nitrogen as cooling media in vacuum furnaces. The data includes five different highly alloyed materials.
