J., 1921- Exploratory stress-corrosion cracking tests on some low-alloy high-strength steels [electronic resource] / G.J. Biefer, Physical Metallurgy Division. Ottawa : Queen's Printer, 1969. ii, 15 p. : ill. Technical bulletin ; TB 111 Cover title. "May 1969." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 7-8). “Using a test rig in which the test specimens are small bent strips, held in this configuration under spring loading, stress-corrosion cracking (SCC) tests were performed in several media upon four alloys resembling AISI Type 4320 but with different Si and Mn contents. One of the steels had the composition of “HY-Tuf”, a proprietary steel said to have high resistance to hydrogen embrittlement cracking. A steel containing 1.48% Si and 0.68% Mn showed the best all-round resistance to SCC in tests in normal sulphuric acid (with and without a cathodic "poison"), boiling calcium-ammonium nitrate, and 3.5% NaC1 solution, outperforming the steel having the "HY-Tuf" composition"--Abstract, p. i.
