HIGH-CARBON STEEL WIRE WITH NICKEL SUB COATING

摘要

A wire for external exposure, i.e. without chemical binding with a polymer or rubber matrix. The wire has a steel core, a nickel sub-coating and a zinc or zinc alloy top coating above the nickel sub-coating. The steel core has a carbon content exceeding 0.20%. The wire is in a work-hardened state by drawing or rolling. The wire has an excellent corrosion resistance and provides an excellent barrier against hydrogen. Preferable uses are wires in off-shore applications.
