AMPP TM21449-2021, Continuous Measurements for Determination of Aerospace Coating Protective Properties

Product Number: AMPP TM21449-2021

Publication Date: 2021

$109.00

The purpose of this standard Test Method is to provide guidance on the testing and evaluation of coatings for aerospace applications. This Test Method has been developed for use by researchers, manufacturers, and organizations responsible for the manufacture, specification, and use of corrosion protective coatings for aerospace structures. The Test Method details measurement techniques to continuously monitor the combined environmental and mechanical effects that drive coating degradation in laboratory tests. While for many industries, judgements of coating performance may be primarily aesthetic, this Test Method describes direct, continuous measurements of coating degradation processes that are important to aircraft structural integrity.

AMPP TM21451-2023, Evaluation of Carbon and Low-Alloy Steels for Resistance to Stress-Oriented Hydrogen-Induced Cracking (SOHIC)

Product Number: AMPP TM21451-2023

Publication Date: 2023

$109.00

Carbon and low-alloy steels in plate form and their welded products may be susceptible to one or more forms of environmental cracking when exposed to wet H₂S service conditions. These include, for example, (1) sulfide stress cracking (SSC) of hard zones and welds; (2) hydrogen-induced cracking (HIC) in the parent metal; and (3) stress-oriented hydrogen-induced cracking (SOHIC) in the region adjacent to welds of nominally acceptable hardness. Extensive work has been conducted over many years to understand various fundamental and applied aspects of these phenomena. Experiences in refinery wet H₂S operations have directed particular attention to understanding SOHIC and the various metallurgical and environmental parameters that govern its occurrence.

Scope

This standard was prepared to provide a test method for consistent evaluation of pipeline and pressure vessel steels to SOHIC caused by hydrogen absorption from aqueous sulfide corrosion. The test conditions are not designed to simulate any specific service environment. The test is intended to evaluate resistance to SOHIC only, and not to other adverse effects of sour environments such as sulfide stress cracking (SSC), pitting, or mass loss from corrosion.

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).
