The Susceptibility Of Spheroidal Graphite Cast Iron To Hydrogen Induced Stress Cracking

Product Number: 51322-17796-SG

Author: Veronika Djupvik, Cathrine Hartung, Atle H. Qvale, Roy Johnsen, Ida Westermann

Publication Date: 2022

$20.00

Cast Iron with its ancient history, traced back to 6th century BCE1, has been used for centuries to anything from manhole covers & fire hydrants to bridges. However, the development of Spheroidal Graphite Cast Iron (SGCI) or Nodular Cast Iron, in the 1940’s, with resulting improvement in mechanical properties such as ductility and fracture toughness, paved the way for further growth in industrial usage of cast iron.² The material has been adopted by several industries such as automotive-, nuclear-, and wind turbine industry. During the last decade, SCGI has gained increased attention as construction material for subsea equipment in offshore oil & gas production, mainly competing with welded and bolted steel assemblies.

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.

The thermal properties that influence the performance of insulation coatings used for personnel protection – redefining “Safe Touch”

Product Number: 51323-19531-SG

Author: Dr. David Morton, Dr. Francois Pierrel

Publication Date: 2023

$20.00

The majority of insulation coatings used today are used to provide personnel protection to workers in the oil and gas or chemicals industry. These coatings provide a reduction in surface temperature to help prevent burn injuries from accidental contact with a hot surface. Human burn hazard is defined in ASTM C1055-03 and this standard is used in conjunction with ASTM C1057-17 as a method of determining skin contact temperature from a heated surface.

Pallets have been used in transporting and storing goods such as consumables, food & beverages, and chemicals for many years. Pallets have multiple designs and dimensions and can be produced from multiple raw materials such as wood, plastic, and metal. The most common types of pallets are wooden and plastic, while wooden pallets have been used the longest and possess the largest share of the global market.

The Transient pH Distribution of the Electrolyte During Mg Galvanic Corrosion

Product Number: 51324-20878-SG

Author: R. Montoya; A. Ortiz-Ozuna; J. Genesca

Publication Date: 2024

$40.00

To better understand the Mg galvanic corrosion, a gel electrolyte was employed. The gel electrolyte was doped with a pH indicator, serving to unveil and monitor the development of alkaline fronts that evolve in parallel with the evolution of H2. Using RGB (Red, Green, Blue) image processing as a semi-quantitative technique, it became feasible to generate transient 2D maps with proper detail regarding the pH evolution into the electrolyte and to provide new information about the galvanic corrosion of Mg. Findings revealed a significant pH decrease in regions where Mg dissolution was more pronounced. A local anodic polarization was achieved by coupling magnesium with A97075. The findings suggest that Mg hydrolysis is responsible for the local pH drop. Additionally, a biunivocal correspondence has been established between the maximum pH value observed in the electrolyte and the specific location where the Mg(OH)2 compound is generated.

The Truth About TG - The Measurement and Significance of the Glass Transition Temperature

Product Number: 41206-290-SG

Author: Dwight G. Weldon

Publication Date: 2006

$20.00

The glass transition temperature (Tg) is an important property, as it is a reflection of both the type of resins in a coating and its degree of cure. This paper discusses what Tg is, the measurement of Tg, and its relationship to coating performance. Data is presented which indicates that the performance of a coating may depend on the conditions under which it is cured, such that the exact same coating may perform differently depending on the region of the country in which it is used and the time of year in which it is applied.

The Ultrasonically Induced Cavitation Erosion of Fiber Glass Reinforced Epoxy and Nodular Cast Iron (NCI) in Seawater

Product Number: 51319-13296-SG

Author: Abdul Hameed Al-Hashem

Publication Date: 2019

$20.00

An investigation was carried out to study and compare the cavitation erosion behavior of a non-metallic fiber glass reinforced epoxy system and a metallic nodular cast iron (UNS F32800) alloy utilizing an ultrasonically induced cavitation facility in seawater. The cavitation tests were made at a frequency of 20 KHz as per ASTM-G30-90 and at a temperature of 250C. the cavitation action increased the rate of mass loss of both the fiber glass reinforced epoxy and that of the UNS F32800 by several orders of magnitude with respect to stagnant conditions. Cavitation also made the surfaces of the fiber glass reinforced epoxy and UNS F32800 very rough exhibiting large cavity pit in the region of the attacked area as revealed by the scanning electron microscope (SEM). The main mechanisms of failure for the fiber glass epoxy system was due to loss of adhesion of the matrix / fiber glass interface and subsequent removal of the resin as well as glass fibers by the mechanical action of cavitation. However the failure of UNS F32800 was due to severe plastic deformation and the fragmentation of the graphite nodules . Mechanical factors and surface defects were determined to be the leading cause of resin and glass fiber loss for the epoxy system and micro-galvanic activities between the ferrite matrix and graphite nodules for the UNS F32800.
