Hydrogen Induced Cracking

Hydrogen Induced Cracking (HIC) is a mechanical fracture caused by the penetration and diffusion of atomic hydrogen into the internal structure of steel.

Sulphide Stress Corrosion

Sulphide stress cracking (SSCC) has special importance in gas and oil industry, as the materials being processed there (natural gas and crude oil) often contain considerable amount of hydrogen sulphide.

Hydrogen Disbonding Test

Hydrogen disbonding test is done to evaluate the disbonding of bimetallic stainless alloy-steel late for use in refinery high-pressure/temperature gaseous hydrogen service.

Intergranular Corrosion Test

Intergranular Corrosion is localized and adjacent to the grain boundaries. It is very dangerous as the attack can proceed undetected through the material and deteriorate the mechanical properties of the metal.
