Hydrogen Induced Disbonding as per ASTM G146

HID Test as per ASTM G146-Evaluation of Disbonding of Bimetallic Stainless Alloy/Steel Plate for Use in High-Pressure, High-Temperature Refinery Hydrogen Service 

Hydrogen Disbonding Test is carried out on our new and latest Reactor System equipped with high-end specialised safety features.

This practice covers a procedure for the evaluation of disbonding of bimetallic stainless alloy/steel plate for use in refinery high-pressure/high-temperature (HP/HT) gaseous hydrogen service.

Conditions of Hydrogen Partial Pressure and Temperature
with Demonstrated Susceptibility to Hydrogen Disbonding in Refinery High-Pressure Hydrogen Service

Hydrogen Induced Disbonding Test (HID):

This Test provides an indication of the resistance or susceptibility, or both, to HID of a metallurgically bonded stainless alloy surface layer on a steel substrate due to exposure to hydrogen-containing gaseous environments under HP/HT conditions.


This test can be used over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem.

This test can be used to assess the effects of material composition, processing methods, fabrication techniques, and heat treatment as well as the effects of hydrogen partial pressure, service temperature, and cooling rate.
