11353 Timescale Correlation Between Marine Atmospheric Exposure and Accelerated Corrosion Testing

Product Number: 51300-11353-SG

ISBN: 2011 11353 CP

Author: Eliza L. Montgomery, Jerome P. Curran, Luz M. Calle and Mark R. Kolody

Publication Date: 2011

$20.00

Evaluation of metal-based structures has relied on atmospheric exposure test sites to determine corrosion resistance in marine environments. This work uses surface chemistry and electrochemical techniques to interpret the chemical changes occurring on low carbon and stainless steel during atmospheric and accelerated corrosion conditions to find a correlation between its accelerated and long-term corrosion performance.

51317--9745-Corrosion-Fatigue of Steels in Sour Environments: Effects of Strain on the Electrochemical Behavior

Product Number: 51317--9745-SG

ISBN: 9745 2017 CP

Author: Diego Leyser

Publication Date: 2017

$20.00

The effects of cyclic stress and strain on corrosion-fatigue in sweet and sour corrosion were studied with an electrochemical approach. Cold-drawn and cold rolled carbon steel samples were mechanically cycled in a confined and CO2-saturated synthetic seawater solution, and their electrochemical response was acquired with a classic 3-electrode apparatus.

A Comparison of the Pitting and Crevice Corrosion of Directional Drilling Alloys With Oilfield Production Alloys

Product Number: 51320-14432-SG

Author: Manuel Marya

Publication Date: 2020

$20.00

The pitting corrosion and crevice corrosion of oilfield production alloys (e.g., 13Cr/UNS S41000, 17-4PH/UNS S17400, 25Cr/UNS S32750, A286/UNS S66286, 718/UNS N07718) and proprietary austenitic stainless steels for directional drilling (PREN between ~20 to ~45) has been investigated. Specifically, series of electrochemical tests have been conducted to rank the alloys, establish simple correlations between electrochemical parameters, PRENmod, and 3-to-60-day immersion tests in 3.5% NaCl at ambient temperature. For all but one alloy, pitting was absent in stark contrast to crevices. Upon tracking populations and dimensional characteristics of crevices over time, trendlines comparing the susceptibility of the alloys towards crevice corrosion were established. Practical conclusions were reached, including the following: (1) 13Cr consistently developed crevices within days, (2) 17-4PH as well as all traditional directional drilling stainless steels developed crevices within one to five weeks, and, (3) neither 718, 25Cr, nor newer directional drilling alloys with both high nickel and high PRENmod showed any sign of crevices upon being tested up to 60 days. Through a variety of comparisons, this investigation also reveals useful technical directions for the development of new, economical, and fit-for-service Oil & Gas alloys for both production and drilling.

Alloying Effect Of Mo In Martensitic Stainless Steel On Passive Film In H2S-CO2 Environment

Product Number: 51322-17538-SG

Author: Kyohei Kanki, Katsuhiro Nishihara, Masayuki Sagara, Hisashi Amaya, Hideki Takabe

Publication Date: 2022

$20.00

Oil and gas wells are highly corrosive environments because they contain H₂S and CO₂. The 13Cr martensitic stainless steel is widely used in the oil and gas industry because of high good corrosion resistance in CO₂ gas wells. Generally, the addition of Mo increases the passivity of steel. However, the role of Mo in passive films has not been completely clarified.
