Element’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. The tests may be carried out according to ASTM F519 standard for many industries including Oil & Gas, Aerospace and Automotive

Hydrogen embrittlement occurs when metals are subjected to hydrogen uptake during plating processes or as a result of corrosion in the service environment. This causes the metal to lose ductility and toughness and become brittle, resulting in premature failure under static loads.  

There are two types of Hydrogen Embrittlement (HE): Internal HE, which occurs when the hydrogen enters metal during forming, coating, plating, cleaning, and finishing operations; and Environmental HE, resulting from hydrogen being absorbed from the environment. 

Element performs HE testing for coating and plating processes that can cause hydrogen embrittlement in steels, and on the metals in simulated service environments. Our deep knowledge of corrosion testing and years of experience means that we know the challenges of assessing hydrogen-related damage in many industries. 

ASTM F519 test method 

Element performs ASTM F519 for mechanical hydrogen embrittlement evaluation using the following two types of tests

 – Rapid Test, the Rising Step Load (RSL) test per ASTM F1624

 – Sustained Load Test (SLT) - duration 200 hours 

Our Engaged Experts can evaluate subsequent exposure to chemicals in service environments, such as fluids, cleaning treatments or maintenance chemicals.

Galvanically Induced Hydrogen Stress Cracking (GHSC) 

The presence of hydrogen (introduced via corrosion) in a metal may result in reduced ductility and increased susceptibility to cracking in the presence of tensile stress (applied and /or residual). Element’s GHSC testing helps evaluate the hydrogen embrittlement sustainability of the corrosion resistant products and metal materials, when galvanically coupled, as the cathode, to another metal (carbon steel). We perform testing in accordance to NACE MR0175/ISO 15156. 

Hydrogen Induced Stress Cracking (HISC)

Subsea Oil & Gas production equipment is exposed to severe conditions which have led to a number of failures of Corrosion Resistant Alloys (CRAs). Our hydrogen embrittlement testing labs can carry out HISC testing of nickel alloys and duplex stainless steels, widely used in subsea components, to investigate how hydrogen influences materials’ behavior under mechanical stress.
