INVESTIGATION OF STRESS-CORROSION CRACKING OF HIGH-STRENGTH ALLOYS
Abstract
Results are tabulated for bent-beam stresscorrosion tests on specimens of Ladish D6AC, Type 300M, and Vascojet 1000 alloy steels, AM355 and PH 15-7 Mo stainless steel, and B120VCA Ti alloy. The specimens were stressed to 75% of the 0.2% offset yield strength; and tested in air, distilled water, tap water, 0.25% Na2Cr2O7.2H2O solution, 1% marquench salt solution, 3% NaCl solution, trichloroethylene, cosmoline, 4% soluble oil solution, and high humidity. The only alloy to fail consistently because of stress corrosion was Vascojet 1000 alloy steel. Results are tabulated for U-bend stress-corrosion tests on specimens of Ladish D6AC, type 300M, and Vascojet 1000 alloy steels tested in distilled water, tap water, 0.25% Na2Cr2O7.2H2O solution, 1% marquench salt solution, 3% NaC1 solution, trichloroethylene, cosmoline, and 4% soluble oil solution. Failures were recorded for each alloy in distilled water, tap water, salt water an trichloroethylene. The Vascojet 1000 alloy failed in the shortest time; the Ladish D6AC specimens recorded the longest times to failure.
