08085 High Performance Corrosion Resistant Stainless Steels and Nickel Alloys for Oil & Gas Applications

Product Number: 51300-08085-SG

ISBN: 08085 2008 CP

Author: Dirk Aberle and Dinesh C. Agarwal

Publication Date: 2008

$20.00

In a 1998 study, costs for corrosion in USA were estimated to be about 276 billion US-$. One way to reduce this gigantic amount of money is to use modern stainless steels and nickel alloys with excellent resistance to various forms of corrosion in corrosive environments like seawater, brines, oil and sour gas wells.

Corrosion Of Nickle Based Alloy In Batch-Mode Biomass Supercritical Water Gasification(SCWG) System

Product Number: 51322-18030-SG

Author: Haoyang Li, Xue Han, Kaiyang Li, Minkang Liu, Yimin Zeng, Chunbao (Charles) Xu

Supercritical water gasification (SCWG) is a promising thermochemical conversion technology in which supercritical water is used as the medium to convert different types of wet biomass (such as wastewater sludge, food waste or microalgae) and even crude bio-oils into hydrogenrich syngas without the need of costive pre-drying process.¹ During typical SCWG conversion at temperature and pressure above the critical point of water (i.e., 374℃ and 22.1 MPa), alkali metal/metal oxide catalysts, carbon-based catalysts and Ni- or Fe-based catalysts are introduced to significantly improve the conversion efficiency on H₂ production.²

There is an increasing interest in substituting nonrenewable fossil fuels with clean and renewable energy resources due to the concerns on the greenhouse gas emissions and the depleting fossil resources. Biomass is a renewable resource derived from living organism and/or their byproducts. For example, some agriculture or forestry wastes (like cornstalk or wood sawdust), industrial wastes (such as black liquor), cattle manure from animal husbandry, and even sewage from our daily life usage can be used for bioenergy production.

Effect of Heat Treatment and Manufacturing Method on the Susceptibility to Hydrogen Induced Stress Cracking of UNS N06625

Product Number: 51324-20899-SG

This paper presents results obtained from examining the effect of heat treatment and production method on the hydrogen induced stress cracking (HISC) susceptibility of UNS N06625 (Alloy 625). Five different versions of Alloy 625 were examined: Hot forged material heat treated at 920 °C, 1010 °C and 1100 °C respectively, material produced by hot isostatic pressing (HIP) and material that has been solution annealed and strain hardened (cold worked) at a temperature below secondary phase formation. The different versions of Alloy 625 were initially characterized by identifying the critical pitting temperature (CPT) by use of a modified ASTM G48 Method C test. Resistance to Hydrogen Embrittlement (HE) has been examined by use of stepwise loading of tensile specimens in a hydrogen charging environment in CortestTM proof rings, followed by fractography characterization and microstructural examination by use of Optical Light Microscope (OLM) and Scanning Electron Microscope (SEM). The hot forged and the HIP’ed versions of Alloy 625 that subsequently were heat treated, were found to be susceptible to HISC. The evaluation was based on a decrease in strength and ductility, as well as brittle fracture surfaces and secondary cracking on the samples’ outer surface. Among the hot forged and heat-treated versions, the samples heat treated at 1010°C were found to be the most susceptible to HISC, while (solution) heat treatment at 1100°C resulted in the lowest HISC susceptibility amongst the hot forged and heat-treated qualities. The solution annealed (1150 °C) and cold worked version showed a higher resistance to HISC, as no reduction in fracture strength, nor any secondary cracking were observed. The amount of grain boundary precipitations was found to be the main factor influencing the HISC susceptibility, where an increased amount of grain boundary precipitations led to higher susceptibility. The effect of grain size on the HISC susceptibility of samples charged with hydrogen were also considered, and the results indicate that larger grains have a beneficial effect on the ductility.

Stress Corrosion Cracking (SCC) and Electrochemical Corrosion Study of Cold Formed Alloy 625 (UNS N06625) In Extremely Low pH and High Chloride Conditions

Product Number: 51322-17782-SG

Author: Suresh Divi, Sri Krishna Chimbli

Publication Date: 2022

$20.00

Alloy 625 (UNS N06625) is an austenitic solid solution strengthened nickel-chromium-molybdenum alloy containing niobium. The high alloy content of alloy 625 enables it to withstand a wide variety of severe corrosive environments. In mild environments, such as ambient atmosphere, fresh and seawater, neutral salts and alkaline media, there is almost no attack.
