SCC Of Alloy 82 Weld Metal In BWR Water

Product Number: ED22-17242-SG

Author: Peter L. Andresen, Katsuhiko Kumagai

Publication Date: 2022

$20.00

There is extensive evidence from laboratory data and plant experience of the SCC susceptibility of Alloy 82 weld metal in both BWR and PWR environments. Two international expert panels evaluated laboratory data under PWR conditions and created disposition curves to address the effects of stress intensity factor (K), temperature, and other factors. Another expert panel is creating a disposition
curve under BWR conditions for K, temperature, corrosion potential, impurities, and other factors. Nickel alloy weld metals at lower Cr levels (~15% Cr for Alloy 182 and ~20% Cr for Alloy 82) are more susceptible to SCC than weld metals of higher Cr content (~30% Cr for Alloy 52/152). This paper focuses on on-thefly effects on SCC growth rate of Alloy 82 weld metal in BWR environments of corrosion potential, water
purity and temperature.

Stress Corrosion Cracking Behaviour Of Thermally Aged Alloy 182

Product Number: ED22-17291-SG

Author: Siddharth Suman, Hans-Peter Seifert, Philippe Spätig, Stefan Ritter

Publication Date: 2022

$20.00

Alloy 182 is an austenitic (FCC) nickel base Ni-Cr-Fe-Mn weld metal that is used as a weld filler or weld pad metal to join stainless steel reactor internals, reactor instrumentation penetrations and main coolant piping to the low-alloy steel reactor pressure vessel. Stress corrosion cracking (SCC) in alloy 182 dissimilar welds is one of the most important material degradation problems and an ongoing issue in boiling (BWR) and pressurized water reactors (PWR) world-wide with potential safety concerns.
Thermally activated preferential local ordering (unlike atom pairs is greater than that in a random solution) of elements within a lattice, over spatial dimensions that are typically on the order of a few nearest neighbor spacing 20 to 50 Å (2 to 5 nm) is referred as short range ordering (SRO). SRO causes lattice contraction and induces additional stress which is claimed as the driving force for SCC in the alloy 600, alloy 690, and alloy 182.

Stress Corrosion Cracking of Carbon Steel in CO2 Liquefaction Plant

Product Number: 51324-20393-SG

Author: Qiang Liu, Lawrence Lau, Shoba Kanda, Luigi Esposito

Publication Date: 2024

$40.00

Carbon dioxide is produced during ethanol fermentation. In order to prevent CO2 emission, gas CO2 is compressed, dried, liquefied, and injected into the reservoir for enhanced oil recovery. Under the operating condition of 2200 kPag and -20°C, the entrained ethanol is dropped out of liquefied CO2. The separated ethanol phase at local site resulted in trans-granular stress corrosion cracking of carbon steel piping and heat exchangers. The investigation involves CO2/ethanol phase behavior study, sourcing contaminants, and failure analysis. It is concluded that 1) ethanol stress corrosion cracking (SCC) is the root cause of the failure in presence of water, chloride and oxygen at pH of 3.0. 2) hydrogen stress cracking is the secondary damage mechanism. Trace of H2S originated from sulfate reducing bacteria (SRB) in ethanol plant and was carried over to the liquefied CO2. Its concentration was increased in the ethanol phase. Mitigation of SCC is approached by reducing ethanol carry-over, minimizing O2 ingress, and lowering the level of other contaminants.

Stress Corrosion Cracking Testing Of Laboratory Processed 304/304L Stainless Steel Elbows And Pipe

Product Number: ED22-18591-SG

Author: Denise J Paraventi, Justin R Hesterberg, Tyler E Moss, and Stephen C Healey

Publication Date: 2022

$20.00

Stress corrosion cracking (SCC) of austenitic stainless steels, while not as prevalent as that in nickelbased alloys such as Alloy 600 and Alloys 82/182, has been observed in the primary system of commercial pressurized water reactors. These instances of SCC have been associated with water chemistry issues and/or occluded regions; however, in many cases high levels of cold work were also present in the material as well.

The Temperature Functionality of Sensitized Stainless Steel SCC Growth in Deaerated Water

Product Number: ED22-17110-SG

Author: David Morton, Elaine West, Tyler Moss and George Newsome

Publication Date: 2022

$20.00

The SCC of stainless steels has been an issue facing light water reactors (LWRs) since 1965 when sensitized components failed in the Dresden boiling water reactor (BWR). Numerous experimental efforts have been performed to characterize the SCC of stainless steel in LWRs in the last several decades and many of these efforts have been reported at each of the prior Environmental Degradation of Materials Conferences. Recent research has focused on characterizing SCCGR dependencies in hydrogen deaerated water. Testing of cold worked (CW) stainless steel has shown that heavily CW stainless steel has Arrhenius temperature functionality with a thermal activation energy of roughly 75 kJ/mol . In moderately to low CW stainless steel, a departure from Arrhenius temperature functionality is observed due to high temperature SCCGR retardation (HTR). This paper further extends this research and describes tests which were conducted to characterize the SCCGR temperature dependency of sensitized and CW 304 SS in hydrogenated water.

Theory and testing of composite materials on Stress Corrosion Cracking

Product Number: 51323-19002-SG

Author: Casey Whalen, Omar Ramirez

Publication Date: 2023

$20.00

Stress Corrosion Cracking, or SCC, is part of a group of cracks commonly known as Environmental Cracking. Additional types of cracks found in this group include corrosion fatigue and hydrogen embrittlement. It is generally known that SCC requires three factors to be present to form and continue growing. The first is a susceptible material. In the world of pipelines, carbon steel is quite susceptible to corrosion when buried but is typically protected from this threat utilizing a combination of external coatings in cathodic protection.
