ASTM A1032 Hydrogen Embrittlement Resistance for Steel Wire

Scope:

ASTM A1032 test method establishes a standard for providing pipes with long-term performance. The time passed by the stressed wire specimen in tolerating a heated solution of NH₄SCN without failure is its resistance to hydrogen-induced embrittlement.

Test Procedure:

Prepare a test specimen for ASTM A1032 testing by sealing the ends of the cell and placing it in a tensile force frame. After applying the tensile force, the test cell is to be filled with a preheated solution of NH₄SCN. The temperature of the solution and the tensile strength should be as per the force requirements. A chronometer should be used to record the time of failure.

Specimen Size : 

In ASTM A1032, a specimen is cut from the wire test unit with a minimum length of 150 mm exposed to the test solution.

Data:

A test unit consists of 1500 mm (60 in.) of wire from a coil of wire and the solution is preheated to 50°C. All the data in ASTM A1032 testing is expressed in SI units.

Conclusion:

ASTM A1032 test method establishes a standard for providing pipes with long-term performance.
