Title
Standard Practice for Evaluating Stress- Corrosion-Cracking Resistance of Metals and Alloys in a Boiling Magnesium Chloride Solution
ASTM International
Publication Date:
Feb 15, 1994
Scope:
This practice describes a procedure for conducting stress-corrosion cracking tests in a boiling magnesium chloride solution. Although this test may be performed using various concentrations of magnesium chloride, this procedure covers a test solution held at a constant boiling temperature of 155.0 ± 1.0°C (311.0 ± 1.8°F). The boiling points of aqueous magnesium chloride solutions at one atmosphere pressure as a function of concentration are shown graphically in Fig. 1.2 A suggested test apparatus capable of maintaining solution concentration and temperature within the prescribed limits for extended periods of time is also described herein.3
The boiling magnesium chloride test is applicable to wrought, cast, and welded stainless steels and related alloys. It is a method for detecting the effects of composition, heat treatment, surface finish, microstructure, and stress on the susceptibility of these materials to chloride stress corrosion cracking.4
This practice is concerned primarily with the test solution, which may be used with a variety of stress corrosion test specimens, surface finishes, and methods of applying stress.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Section 7 for specific safety precautions.
2 Available data on the relationship of concentrations and boiling points of magnesium chloride solutions are critically reviewed and supplemented by I. B. Casale in “Boiling Points of Magnesium Chloride Solutions—Their Application in Stress Corrosion Studies,” Corrosion , Vol 23, 1967, pp. 314–17.
3 The apparatus and test procedures for maintaining constant boiling temperatures of magnesium chloride solutions for stress corrosion tests are described by M. A. Streicher and A. J. Sweet in Corrosion, Vol 25, 1969, pp. 1–6.
4 The use of concentrated magnesium chloride solutions for determining the susceptibility to stress corrosion cracking of austenitic and ferritic stainless steels and related nickel-base alloys was first described by M. A. Scheil, Symposium on Stress Corrosion Cracking of Metals, ASTM STP 64, ASTM, 1945, p. 395. (Although currently out of print, copies may be obtained from University Micro- films, Inc., 300 North Zeeb Rd., Ann Arbor, MI 48106.)
