Service Overview
Metallographic Testing
Metallographic testing plays a vital role in evaluating material quality during manufacturing and processing. By examining the microstructure of metals, manufacturers gain insights into material performance, heat treatment effectiveness, and possible structural defects. This enables optimization of production processes, improved quality control, and verification of compliance with relevant industrial standards.
Comprehensive metallographic analysis is used to assess characteristics such as grain size, inclusions, phase distribution, surface layer treatments, and fracture behavior. This is especially critical for applications involving steels, aluminum alloys, castings, forgings, and high-performance parts in automotive, aerospace, and machinery industries.
