Hardness Testing Services for Aerospace & Oil & Gas 

Accredited Hardness Testing with Precision and Speed 

Why Hardness Testing Matters 

Hardness testing is one of the most fundamental and widely used evaluations in materials engineering. It provides essential data about a material’s strength, wear resistance, and heat treatment quality, allowing engineers to predict performance under load and identify surface inconsistencies that could lead to premature failure. 

AADFW’s hardness testing helps engineers and quality teams: 

• Confirm heat treatment and surface hardening results. 
• Evaluate weld zones and base metal consistency. 
• Correlate hardness with tensile strength and material performance. 
• Verify compliance with ASTM, ISO, and ASME hardness standards. 

In industries where safety and reliability are paramount, accurate hardness testing ensures materials perform exactly as designed — from turbine blades to pipeline steels. 

AADFW’s Approach to Hardness Testing 

AADFW performs hardness testing with engineering precision, accredited methodology, and rapid reporting. Our metallurgists use properly calibrated Rockwell, Brinell, Vickers, and microhardness systems to measure both bulk and localized hardness across a wide range of metals and coatings. 

What makes AADFW different: 

• Accredited and precise — Testing under NADCAP and ISO/IEC 17025 accreditation. 
• Faster turnaround than large global labs, with efficient sample processing. 
• Trusted by aerospace and oil & gas engineers for consistent, traceable data. 
• Expert metallurgists interpret results and advise on heat treatment verification and material behavior. 

Hardness Testing Capabilities 

AADFW offers a comprehensive suite of hardness testing methods to evaluate surface and subsurface mechanical properties for materials, welds, and coatings. 

• Rockwell Hardness Testing (HRB, HRC, HR15N, HR30T, etc.) – Rapid, standardized testing for metals and alloys per ASTM E18 and ISO 6508. 
• Brinell Hardness Testing (HBW) – Ideal for coarse-grained or uneven materials like castings, forgings, and thick plates. 
• Vickers Hardness Testing (HV) – Micro- to macro-scale indentation for fine-grained metals, thin sections, or coatings. 
• Knoop Microhardness Testing – Precision testing for small parts, weld zones, and surface coatings per ASTM E384. 
• Portable Hardness Testing – On-site verification of large or installed components. 
• Hardness Mapping – Cross-sectional profiles to evaluate heat-affected zones (HAZ) and case depth in treated materials. 
• Correlation Testing – Converts hardness data to estimated tensile strength or yield strength when required. 

All testing is performed using calibrated equipment and traceable reference blocks to ensure measurement accuracy.
