... Abstract UNS N08935 is a new versatile austenitic alloy with the composition 35Ni-30Fe-27Cr-6.5Mo-0.28N and a PREN of 52. It has an extreme pitting resistance which makes the grade a good candidate for O&G applications. The alloy is available in several strength levels with good ductility...

... Abstract The comparison of the pitting resistance of alloys with high corrosion resistance can be challenging, as CPT-values (critical pitting temperatures) are often above the boiling point of the test solutions. For high-nickel alloys, the use of potentiostatic electrochemical methods...

... Abstract ATI has developed ATI 642 ™† alloy, a new Ni-Cr-Mo corrosion-resistant alloy that displays significant resistance to sensitization from the effects of hot-clad bonding and welding operations. The new alloy is unique because of its substantial Fe content, which gives it a significant...

... Abstract Operating temperatures above 700°C are desired to improve the efficiency of power generation systems such as microturbines. Therefore, the use of creep-resistant Ni-based or Fe-based alloys, which can form protective Cr 2 O 3 and Al 2 O 3 scales, is required. In this paper, Fe...

... ABSTRACT Two commonly used aluminum alloys, namely 5083 and 6061, in fabrication of Aluminum Plate Heat Exchangers (APHE) were tested under four-point bending at different volumes of mercury and stress to measure their susceptibility to liquid metal embrittlement (LME) by mercury. The test...

... users is to get the specific grade which can resist to corrosion while minimizing the cost. The API 5CRA standard defines corrosion resistant alloy (CRA) grades for casings and tubings, from group 1 named “Super 13Cr 13 -5-2” (suitable up to 180°C), to group 2 “Duplex” grades 22-5-3 (232°C) or “Super...

... ABSTRACT Environmentally assisted cracking of high strength PH nickel based alloys 725, 945X, and 955 were evaluated under subsea HPHT environments. The two primary environments of interest in this effort were in 3.5wt% NaCl, pH = 8.2 under cathodic polarization at low temperature 40°F...

... ABSTRACT Carbon steels are widely used in the oil and gas exploration and production service. However, these materials are prone to corrosion and cracking in CO 2 /H 2 S. The propensity to cracking increases when higher strength grades are employed. The use of corrosion resistant alloys...

... ABSTRACT Copper alloys are widely used for the heat exchanger tubes in both multi-stage flash (MSF) and multiple effect distillation (MED) thermal desalination plants. Millions of metres of such tubing have been used and, generally, the copper alloys give good performance. In the last few...

... ABSTRACT A previously developed modeling framework has been extended to predict the general and localized corrosion of various corrosion resistant alloys (CRAs), including alloys 2507, 2535, 28, 29, S13Cr, S15Cr, and S17Cr in complex aqueous systems relevant to oil and gas production...

... ABSTRACT Precipitation Hardened (PH) nickel alloys have been used extensively and successfully in the Oil & Gas Industry for many years. These materials offer high strength and outstanding corrosion resistance in many aggressive environments and they are a common selection for high...

... ABSTRACT It is a well admitted fact that oxygen contamination shall be avoided during H 2 S cracking tests of low alloy steels. In the 2016 revisions of NACE TM0177 and NACE TM0284 documents, quantitative limits of O 2 contamination were included with thresholds at 10 and 50 ppb of dissolved...

... ABSTRACT Super martensitic stainless steels are widely used in oil & gas production environments) for mitigation of general corrosion due to the presence of CO 2 in the produced fluids providing a cost-effective alternative to more expensive corrosion resistant alloys (CRA. However...

... ABSTRACT Corrosion Resistant Alloys (CRAs) are routinely utilized to mitigate against the complex damage mechanisms encountered in refining operations that carbon and low alloy steels are highly susceptible to. However, CRA materials can suffer similar corrosion damage when improperly...
