Traditional and new methods of hardness measurement are available. Deciding which one is right for an application depends on several factors.

Peters’ Heat Treating Inc. recently earned Nadcap certificates in Heat Treating and AC7004 Aerospace Quality Management System at its Meadville, Pa., facility. The company is focused on continuing to improve its processes and services in order to service all customer needs. Nadcap provides a standardized approach to quality assurance for the aerospace industry. Accredited companies must have a stringent quality system in place and be able to pass annual audits to keep the certifications active.

Solar Atmospheres of Western PA (SAWPA) successfully achieved Nadcap AC7101/4 accreditation for its captive metallography laboratory and became an approved Boeing Process Source (D1-4426). The accreditation will allow SAWPA to test for microhardness, surface contamination, intergranular oxidation and grain size in accordance with various aerospace specifications, including many Boeing process specifications. Furthermore, the accreditation will reduce SAWPA’s dependence on outside testing facilities and provide its customers with a single-source supplier capable of meeting all testing needs internally. Along with the laboratory accreditation, SAWPA continued the 24-month merit status for Nadcap heat treating.

The semiautomatic HMV-G21testing system is designed for measuring the hardness of small parts and metallic structures used in precision equipment, processed surface layers and metal plating layers.
