AMPP TM21453-2023, Laboratory Testing for Resistance to Environmentally-Assisted Hydrogen Stress Cracking in Welds

Product Number: AMPP TM21453-2023

Publication Date: 2023

$109.00

This standard covers the testing of welds subjected to tensile stresses for resistance to cracking in aqueous environments containing a source of hydrogen charging. Carbon and low alloy steels and their matching welds are commonly tested for EAC resistance at room temperature where susceptibility is typically high. For other types of alloys, the correlation of EAC susceptibility with temperature is more complicated. For example, dissimilar welds of nickel alloy on carbon or low alloy steel have shown susceptibility at low, seabed temperatures (4 °C [39 °F]). Matching welds made on duplex stainless steels have shown similar susceptibility (DNV RP-F112).
