Hardness Testing

Hardness Testing is a fundamental mechanical test used to determine a material’s resistance to indentation, penetration, or scratching. It provides valuable information about material strength, wear resistance, and heat treatment effectiveness, making it an essential tool in quality control and material verification.

Common Hardness Testing Methods:

• Brinell Hardness Test (BHN): Uses a hardened steel or tungsten carbide ball to measure indentation hardness.
• Rockwell Hardness Test (HR): Uses different indenter types (diamond cone or steel ball) and loads for quick, versatile testing.
• Vickers Hardness Test (VHN): Uses a diamond pyramid indenter for precise micro and macro hardness measurements.
• Portable Hardness Testing: Ultrasonic or rebound-type testers for on-site hardness evaluation of large components.

Hardness testing is widely applied for:
• Assessing welds, forgings, castings, and heat-treated components
• Evaluating surface hardening, carburizing, or nitriding effectiveness
• Quality control in manufacturing and fabrication processes
• Material selection and verification against international standards
