Standard Test Method for Hydrogen Embrittlement Resistance for Steel Wire Hard-Drawn Used for Prestressed Concrete Pipe

Importancia y uso:

4.1 Hard-drawn steel wire as used in prestressed concrete pipe may be exposed to elemental hydrogen favorable to hydrogen induced embrittlement and cracking. Resistance to hydrogen embrittlement is necessary for prestressing wire to provide long-term performance to installed pipe.

4.2 The length of time that a stressed wire specimen resists failure while exposed to a heated solution of NH₄SCN, is an indication of the specimen's resistance to hydrogen embrittlement.
