Alloy UNS N06058: A solution for demanding corrosive applications where common members of the Ni-Cr-Mo alloys experience their limits

Product Number: 51320-14557-SG

Author: D. Niespodziany, R. Behrens, H. Alves

Publication Date: 2020

$20.00

The high performance alloy UNS N06058 contains about 21 wt.-% chromium and at least 18.5 wt.-% molybdenum. It is the first member of the Ni-Cr-Mo alloys intentionally strengthened with nitrogen. Based in the combination of its alloying constitutes this alloy is highly resistant to oxidizing as well as to reducing corrosive media. Evidenced by the high Pitting Resistance Equivalent (PRE) number of about 86 the alloy UNS N06058 shows an outstanding resistance to localized corrosion as well.

The objective of this paper is to outline the characteristics of alloy UNS N06058 and therefore to highlight the successful use of it in demanding corrosive applications in the process industry and other sectors.

Main characteristics such as microstructure, mechanical properties and fabrication will be discussed. The very good weldability of alloy UNS N06058 has been verified by the German TÜV1. A matching filler metal, which is officially qualified according to AWS 5.14 (American Welding Society)2, is available. In addition, prior work shows that alloy UNS N06058 can be reliably explosion clad. Furthermore, corrosion resistance determined under laboratory conditions as well as in field studies will be presented not only for the base material but also exemplary on welded and cladded samples. Examples of applications will complete the comprehensive overview of this work.

Casing Corrosion in Geothermal Environments Containing Sulfuric Acid

Product Number: 51324-20932-SG

Author: Joseph Thevakumar; Joshua Owen; Richard Barker; Evgeny Barmatov

Publication Date: 2024

$40.00

This work focusses on understanding corrosion severity and material performance within model geothermal sulfuric acid (H2SO4)-containing environments. With the use of a tantalum-lined high pressure/high temperature autoclave, the corrosion behavior of N80 carbon steel was compared against duplex stainless steel when exposed to H2SO4 solutions (pH 2-4) at temperatures up to 150°C. Electrochemical linear polarization resistance measurements were implemented to gather real time corrosion kinetic data. Complimentary ex-situ analyses (scanning electron microscopy and white light interferometry) were conducted to understand the corrosion mechanism and quantify localized corrosion rates. A quantitative relationship was identified in terms of pH, temperature and metal corrosion for the selected materials to highlight material capability within such low pH geothermal environments.

The crude oil produced by fracking or hydraulic fracturing method are high in sulfur content (0.5%)1. The vast majority of vessels that are used in the petrochemical industry to store and transport materials are constructed using Carbon steel. Coating linings used for corrosion protection inside of vessels and tanks must perform under severe conditions such as an exposure to corrosive gasses ( H₂S) and carbon dioxide as well as high temperatures, high pressures and often must withstand the cold wall effect and rapid decompression.

Corrosion Fatigue and Chloride-Induced Stress Corrosion Cracking in Sulfur Recovery Units

Product Number: 51324-20691-SG

Author: Saud I Al Otaibi; Mohamud Farah

Publication Date: 2024

$40.00

Sulfur Recovery units (SRUs) are widely used in the oil and gas industry to recover sulfur from refined products and acid gas waste from the natural gas process. This involves routing acid gas rich in hydrogen sulfide through a reaction furnace to produce molten sulfur in a thermal Claus reaction. Central to the operation of the SRUs is the Sulfur storage pit, which is an underground high depth structure used to temporarily store sulfur product before shipment. Sulfur pits contain a range of critical equipment and piping, such as sulfur product pumps and steam coils.The pumps are crucial for shipping the sulfur product, while the steam coils are used for maintaining the molten sulfur temperature between 270-280 °F to prevent solidification and higher sulfur viscosity. Consequently, any impact to the integrity of this equipment impacts the unit’s operational efficiency or worse, leads to total unit shutdown. This equipment is susceptible to a range of damage mechanisms resulting from both operational conditions, such as sulfuric acid corrosion and environmental cracking, resulting from steam leakage and ground water seepage respectively. This paper investigates sulfuric acid corrosion and corrosion fatigue — in sulfur pumps — resulting from the synergistic effects of both dynamic loading and chloride-induced pitting corrosion. The steam coils in the pit were also found to suffer from both sulfuric acid corrosion and chloride stress corrosion cracking. These damage mechanisms were determined following extensive metallurgical analysis of samples recovered from the pit. Furthemore, laboratory compositional analysis from various samples collected from the pumps and the pits showed significant quantity of sodium chloride, resulting from ground water ingress alongside corrosion, and cementitious products, such as iron sulfide, quartz – SiO2 and iron sulfate. These findings, alongside sample results of the post-inspection findings for the sulfur recovery unit pit and equipment, will be highlighted and discussed. Effective mitigations, including the use of permanent dewatering, will also be discussed.
