By investigating the physical properties of liquid ammonia and conducting a literature review, we will perform appropriate pretreatment and carry out highly accurate tests!
We offer the "Liquid Ammonia Stress Corrosion Cracking Test" as an evaluation of the corrosiveness and stress corrosion cracking (SCC) susceptibility in a liquid ammonia environment. This is useful for material selection for liquid ammonia storage tanks and transport piping that are compatible with carbon neutrality. Additionally, combinations of test conditions such as temperature, pressure, duration, and various additives can be accommodated as needed. 【Test Conditions】 ■ Test Temperature: -30 to 40℃ ■ Test Pressure: 0 to 3 MPa ■ Test Duration: Up to 1 month ■ Atmosphere: Air, nitrogen, oxygen, etc. ■ Test Specimens: Flat plates, U-bend test specimens, 4-point bend test specimens ■ Measurement Methods: Natural potential measurement, constant potential test, constant current test, total polarization measurement, etc. *For more details, please download the PDF or feel free to contact us.
