Hydrogen Embrittlement Testing

Hydrogen embrittlement (HE) testing is also called hydrogen assisted cracking (HAC) testing and hydrogen-induced cracking (HIC) testing. The Hydrogen embrittlement testing is a test to evaluate the cracking of steel in the wet hydrogen sulfide environment due to the absorption of hydrogen due to material corrosion. There are three main required aspects that promote failure due to hydrogen embrittlement:

• A susceptible material, typcially a high strength metallic alloy

• Exposure to an environment that contains hydrogen and promotes formation of atomic hydrogen. This can be permanent (sour gas environment, hydrogen proplled industry cycles) or non-permanent (galvanic coating)

• The presence of internal tensile stresses due to residual and/or applied stresses

T,C&A Lab's Hydrogen Embrittlement (HE) testing determines the performance of materials in a corrosive environment under the influence of the tensile stress by evaluating the material's ductility as a result of hydrogen absorption according to ASTM standards.

The test solutions we provide include but are not limited to:

• Hydrogen embrittlement test

• Hydrogen embrittlement corrosion analysis

• Hydrogen embrittlement fracture analysis

• Hydrogen embrittlement inspection

• Hydrogen embrittlement metallographic inspection

• Hydrogen embrittlement morphology analysis

• Hydrogen embrittlement crack analysis

• Galvanically induced hydrogen stress cracking (GHSC)

• Hydrogen induced stress cracking (HISC)

Hydrogen embrittlement testing can be applied to

Pipeline steel and pressure vessel steel, boilers, liquefied gas tanks, valves, flanges, welds, carbon steel, stainless steel and other metal materials and finished products working in a corrosive environment containing sulphide aqueous solution.
