Description

The term "Super-Duplex" denotes high-performance Duplex steel based on elevated contents of chromium, nickel and molybdenum. These elements improve pitting corrosion resistance, while additions of nitrogen promoted structural hardening, raising the yield strength and ultimate strength values without impairing toughness.
