This book was released on 2018-07-12 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stress corrosion cracking (SCC) evaluation was undertaken on HP 9Ni-4Co-0.20C steel in support of the Advanced Solid Rocket Motor (ASRM) program. This alloy was tested in plate, bar, and ring forging forms. Several heat treating procedures yielded ultimate tensile strengths ranging from 1,407 to 1,489 MPa (204 to 216 ksi). The test environments were high humidity, alternate immersion in 3.5-percent NaCl, and 5-percent salt spray. Stress levels ranged from 25 to 90 percent of the yield strengths. The majority of the tests were conducted for 90 days. Even though the specimens rusted significantly in salt spray and alternate immersion, no failures occurred. Therefore, it can be concluded that this alloy, in the forms and at the strength levels tested, is highly resistant to SCC in salt and high humidity environments. Torres, Pablo D.

Book excerpt: A stress corrosion cracking (SCC) investigation was conducted on HP 9Ni-4Co-0.30C steel plate welds (welded by using straight polarity plasma arc and HP 9Ni-4Co-0.20C weld wire) since this material is being considered for use in the Advanced Solid Rocket Motor (ASRM) program. Prior to the welding, the material was double tempered at 538 C (1,000 F). After welding, only part of the material was stress relieved at 510 C (950 F) for 3 h. Round tensile specimens obtained from nonstress-relieved material were tested in 100-percent relative humidity at 38 C (100 F), in 3.5-percent NaCl alternate immersion, and in 5-percent salt spray at 35 C (95 F). Specimens obtained from stress-relieved material were tested in alternate immersion. The stress levels were 50, 75, and 90 percent of the corresponding 0.2-percent yield strength (YS). All the nonstress-relieved specimens exposed to salt spray and alternate immersion failed. Stress-relieved specimens (exposed to alternate immersion) failed at 75 and 90 percent of YS. No failures occurred at 50 percent of YS in the stress-relieved specimens which indicates a beneficial effect of the stress relief on the SCC resistance of these welds. The stress relief also had a positive effect on the mechanical properties of the welds (the most important being an increase of 21 percent on the YS). Under the conditions of these tests, the straight polarity plasma are welded HP 9Ni4Co-0.30C steel plate was found highly susceptible to SCC in the nonstress-relieved condition. This susceptibility to SCC was reduced by stress relieving. Torres, Pablo D. Marshall Space Flight Center...

This book was released on 1966 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since all current aircraft strctural steels exhibit some degree of stress-corrosion cracking (SCC), the recently developed steels, HP 9-4-30 and HP 9-4-45, were investigated to define their limits of stress-corrosion susceptibility or immunity. Stress-corrosion testing variables included HP 9-4-30 Martensite (220/240 KSI), HP 9-4-45 Martensite (260/280 KSI), and HP 9-4-45 Bainite (260/280 KSI); normal and severe grinding and drilling, flash and fusion welding, stress relief, 400 F service exposure, shot-peening, and cadmium-plating. Effects of microstructures, pre-existing cracks, surface conditions, and residual stresses (X-ray diffraction) were determined. HP 9-4-30 Martensite was immune to SCC in the as-heat-treated, H.T. (heat treated) and ground, H.T. and drilled, H.T. and shot-peened, and H.T. and cadmium-plated conditions, but was susceptible in the H.T. and severely ground, H.T. and severely drilled, H.T. and fusion-welded, and H.T. and pre-cracked conditions. The SCC threshold for tempered martensite was above 205 KSI and between 90 and 120 KSI for untempered martensite. HP 9-4-45 Martensite was very susceptible to SCC for all variables tested, except shot-peening (immune). The cadmium-plated condition was the most susceptible. The SCC threshold for tempered martensite was between 89 and 127 KSI. HP 9-4-45 Bainite was immune to SCC in the as-heat-treated, H.T. and shot-peened, and flash welded and H.T. conditions, but susceptible in the H.T. and cadmium-plated, and H.T. and pre-cracked conditions. Severe grinding and severe drilling conditions contained SCC only in the martensenic surface layer.

This book was released on 1964 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stress corrosion susceptibility of several high strength steels has been evaluated by alternate-immersion laboratory testing in a 3.5-percent sodium chloride solution. The steels evaluated were the stainless steels AFC 77, AM 350, AM 355, and 17-4PH; the low alloy steels D6AC, 4335M, 4340, H-11, 4330M, and HY-Tuf; and the high nickel steels 18Ni-9Co-5Mo, 18Ni-7Co-5Mo, and 9Ni-4Co. The variables investigated were product form, grain direction, tensile strength level, stress level, cold working, ausforming, welding, and protective coatings. Detailed results relating stress corrosion susceptibility to the variables and alloys studied are included. Notch tensile and fatigue cracked fracture toughness testing was carried out for correlation with stress corrosion susceptibility. Optical microscopy, electron microscopy, and X-ray diffraction studies were made to supplement the mechanical property and stress corrosion testing. A literature survey of related stress corrosion test data is included.
