Sulfide Stress Cracking Testing

Sulfide stress cracking is a form of hydrogen stress cracking on the surface of metal materials related to acid corrosion and tensile stress. High-strength metal materials and hard weld areas are susceptible to sulfide stress cracking.

Sulfide stress cracking testing is used to evaluate the cracking of material under the combined action of tensile stress and corrosion in the presence of water and H₂S.

STEMart carries out professional sulfide stress cracking testing to evaluate the susceptibility of materials to stress corrosion cracking in a wet H₂S environment, and helps customers select suitable materials for working in H₂S media.

Test Capabilities

• Uniaxial tensile testing: Evaluate the resistance of metal materials to cracking failure under uniaxial tensile loading.
• Bent-beam testing: Evaluate the resistance of carbon and low-alloy steels in flat shape to cracking failure in the presence of a stress concentration.
• C-ring testing: Evaluate the resistance of metal materials to cracking failure under circumferential loading.
• Double-cantilever-beam testing
• Four-point bend testing

STEMart's expert team can help you select the most appropriate method to evaluate the susceptibility of the material to sulfide stress cracking. For more information about our sulfide stress cracking testing services, please contact us.
