Hardness Testing

Introduction

Hardness Testing is a fundamental material evaluation method used to determine a material’s resistance to deformation, wear, and indentation. It is widely used in Oil & Gas, Petrochemical, Power Generation, Manufacturing, Fabrication, Marine, and Structural Engineering to verify material properties, assess heat treatment effectiveness, and ensure compliance with engineering specifications.

Hardness Testing is essential for weld inspection, material verification, in‑service component assessment, and failure analysis. Common hardness methods include Brinell (HB), Rockwell (HRC/HRB), Vickers (HV), and Portable Hardness Testing using devices such as Leeb, UCI, and rebound testers.

This GTMCS Hardness Testing program provides comprehensive training in hardness principles, equipment operation, indentation measurement, conversion charts, and compliance with international standards such as ASTM E10, ASTM E18, ASTM E92, ISO 6506, ISO 6507, ISO 6508, and API specifications.
