DNV can help you select materials that will perform well in any operating environment.

We can test materials in a wide variety of environments.

We can address a large range of materials-related problems.

We have full-scale materials analysis capabilities for elemental analyses and metallographic services.

Purpose

It is important to select the right materials to withstand environmental and operating stresses and avoid failures.

Benefits

We have extensive experience in the analysis and selection of materials. Our materials and corrosion specialists include both engineers and Ph.D. scientists with backgrounds in metallurgy, materials science, polymers, corrosion and others. Our diverse staff works together to address a broad range of materials-related problems. These include general and localized corrosion, coating degradation, stress corrosion cracking, high temperature corrosion, corrosion fatigue, thermal fatigue, creep and fracture mechanics.

Our Approach

Various techniques are used to analyze candidate materials and apply the results of these analyses to assist in proper material selection. Some of the techniques employed to analyze candidate materials include:

• DC and AC electrochemistry
• Slow strain rate testing
• Salt spray testing
• Autoclave testing
• Fracture mechanics
• Creep rupture and crack-growth testing
• High temperature corrosion testing
• In-field corrosion testing
• Corrosion fatigue testing
• Fracture toughness testing
