Effect of hydrogen content and percent of real deformation during wiredrawn for high carbon steel in the manufacture of bronze plated steel beadwire

Effect of hydrogen content and percent of real deformation during wiredrawn for high carbon steel in the manufacture of bronze plated steel beadwire

$15.00

This paper explains the effect of hydrogen embrittlement during the production of bead wire. The effect of hydrogen on torsion tests is remarkable after drawing for real deformation (e) levels higher than 2.6 in bronze plating bead wire process. Nonetheless, this situation is not presented for e = 2.01. Ductility is recovered after 30 days at room temperature and can be increased with stress-relieved heat treatment (327.6°F for one hour). A similar situation is observed when the hydrogen amount is occluded in high carbon steel wire.
