Fine Pearlitic Steel Wire

6.5× SCC Resistance

By increasing carbon and silicon content, the pearlite lamellar spacing is refined, reducing both corrosion activity and reversible hydrogen trapping while maintaining the same tensile strength, markedly extending the time to stress corrosion fracture.
