Book excerpt: The corrosion potential of stressed sensitized Type 304 stainless steels were studied in oxygen-containing solutions to determine the relation between potential fluctuations and the initiation of stress-corrosion cracking. An in situ scanning vibrating electrode technique was shown to detect currents coming from growing stress corrosion cracks in dilute thiosulfate solutions at temperatures below 90°C. The onset of the cracking was clearly indicted by rapid decreases in the potential. It was observed that small cracks, which had grown for a limited period, were not susceptible to reinitiation of the cracking process. The onset of cracking was clearly observable by marked decreases in the potential which continued to decrease if cracking remained active and increased when cracking stopped. At and above 200°C there were no potential fluctuation indicative of the onset of stress-corrosion cracking. Small potential differences between platinum and stainless steel were observed demonstrating the presence of a single electrochemically reversible reaction determined the potential of all metals within the stainless steel autoclave, and thus masking the onset of cracking. The presence of only an iron-containing deposit on the platinum suggested that a sufficiently reversible redox couple was set up between deposited iron oxide and a soluble iron species in solution which dominated the potential of the stainless steel and the platinum.

Book excerpt: The problem of stress corrosion cracking (SCC), which causes sudden failure of metals and other materials subjected to stress in corrosive environment(s), has a significant impact on a number of sectors including the oil and gas industries and nuclear power production. Stress corrosion cracking reviews the fundamentals of the phenomenon as well as examining stress corrosion behaviour in specific materials and particular industries.The book is divided into four parts. Part one covers the mechanisms of SCC and hydrogen embrittlement, while the focus of part two is on methods of testing for SCC in metals. Chapters in part three each review the phenomenon with reference to a specific material, with a variety of metals, alloys and composites discussed, including steels, titanium alloys and polymer composites. In part four, the effect of SCC in various industries is examined, with chapters covering subjects such as aerospace engineering, nuclear reactors, utilities and pipelines.With its distinguished editors and international team of contributors, Stress corrosion cracking is an essential reference for engineers and designers working with metals, alloys and polymers, and will be an invaluable tool for any industries in which metallic components are exposed to tension, corrosive environments at ambient and high temperatures. - Examines the mechanisms of stress corrosion cracking (SCC) presenting recognising testing methods and materials resistant to SCC - Assesses the effect of SCC on particular metals featuring steel, stainless steel, nickel-based alloys, magnesium alloys, copper-based alloys and welds in steels - Reviews the monitoring and management of SCC and the affect of SCC in different industries such as petrochemical and aerospace

Available in PDF, EPUB and Kindle. Book excerpt: Scoping stress corrosion cracking (SCC) tests of 304 stainless steel (SS) were performed in 75 C and 250 C aerated pressurized water (APW) and 250 C deaerated pressurized water (DPW). The 250 C APW environment was used to initiate intergranular stress corrosion cracking (IGSCC) and then the water was deaerated and hydrogenated to see if IGSCC continued in 250 C DPW. Tests were performed with and without 200 ppb SO4{sup =}. The 304 SS test materials were evaluated in either the as-received, heavily sensitized (649 C for 1 h), fully sensitized (1099 C for 1 h/water quench/621 C for 17 h) or 20% cold rolled condition. At the beginning of each test sequence, specimens were subjected to continuous cycling with a 500s rise/500s fall or a 5000s rise/500s fall to promote the transition from a transgranular (TG) precrack to an IG crack. After generating a uniform crack under continuous cycling conditions, a trapezoidal waveform with 500s rise/9000s hold/500s fall was used to characterize the SCC behavior. Crack growth rates (CGRs) were monitored continuously with the electric potential drop (EPD) method and were corrected based on physical crack length measurements obtained when specimens were destructively evaluated. Continuous cycling with a 500s or 5000s rise time was found to produce both TG faceting and IGSCC in fully sensitized 304 SS tested in 75 C APW with 7 ppm O2 and 200 ppb SO4{sup =}. However, no measurable crack extension occurred when a 9000 s hold time was introduced. Extensive IGSCC occurred in heavily sensitized and fully sensitized 304 SS in 250 C APW with 1 ppm O2 and 200 ppb SO4{sup =}. IGSCC initiated under continuous cycling conditions with a 500 s rise time, and rapid IGSCC occurred when a 9000 s hold time was introduced. During the trapezoidal waveform test with a 9000 s hold, CGRs ranged from 1 to 3 mils/day for the heavily sensitized material and 5 to 10 mils/day for the fully sensitized material. When the test environment was dearated and hydrogenated to 30 cc H2/kg H2O, CGRs decreased by an order of magnitude ((almost equal to)0.1 mils/day), and the cracking mode in 250 C DPW was predominantly TG. The only material that exhibited evidence of IGSCC in 250 C DPW was 20% cold rolled 304 SS. IGSCC readily initiated in 250 C APW and continued in 250 C DPW. Metallographic and fractographic examinations showed that the IG cracking was highly branched and discontinuous. Results from the scoping SCC tests have revealed significant information regarding the nature of IG and TG cracking of 304 SS in APW and DPW. The key finding is that cold work appears to be more important than sensitization in producing IGSCC in DPW.

This book was released on 1984 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of low-level environmental impurities, test temperature, sensitization heat treatment, and surface condition on crack initiation have been examined in Type 304 stainless steel in constant extension rate stress corrosion cracking tests. Tests were conducted at 288, 200 and 125°C in pure water environments containing 0.2, 0.2, and 1.8 ppm of dissolved oxygen, respectively. At 288°C in highly sensitized specimens, cracks initiated at less than 20% of life in pure water, with impurities accelerating initiation. The bulk pH affected initiation and failure strains, while increasing conductivity at neutral pH affected only strain to failure. At lower temperatures or lesser degrees of sensitization, crack initiation occurred later in life and impurity additions had a stronger impact. Shot-peening reduced the strain to initiation in constant extension rate tests, most noticeably at 125°C. The minimal data available for comparison support the findings of this study.
