51317-9771- A Comparison of Corrosion Resistant, High N Austenitic Stainless Steels

Product Number: 51317-9771-SG
Author: Samuel J. Kernion / Thomas N. Werley
Publication Date: 2017
$20.00

A study of the corrosion resistance of multiple high Nitrogen, high Manganese austenitic stainless steels is presented, focusing on a newly developed alloy with increased pitting resistance. The alloys vary principally by the amount of Molybdenum, Nickel, Manganese, Chromium and Nitrogen.

51318-11163-Evaluation of Corrosion of Austenitic Steels and Comparison with Martensitic Stainless Steel 17-4

Product Number: 51318-11163-SG
Author: Tatiana R. Ayers, Manuel P. Marya, Dean Lauppe
Publication Date: 2018
$20.00

A series of NACE TM0177 Tensile Test Method A tests were conducted on various commercially available chromium-manganese austenitic stainless steels as well as 17-4PH in the 110ksi-to-130ksi yield strength range (34 - 35 HRC max).

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.

Corrosion of Carbon Steel and Alloys in Ammonium Chloride Salt

Product Number: 51314-4007-SG
ISBN: 4007 2014 CP
Author: Kazuhiro Toba
Publication Date: 2014
$20.00

This study was conducted to determine the root cause of aggressive corrosion due to wet NH4Cl salt deposition in reactor effluent streams in hydroprocessing units. In addition corrosion resistance and behavior of carbon steel and alloys in high-concentration NH4Cl solutions were investigated.
