Alloy Grade UNS: CW-6MC – Exceptional Corrosion Resistance

  • Overview

    N26625 is an austenitic alloy with exceptional corrosion resistance and fatigue strength in marine services. It is also highly temperature-resistant and can be easily welded and processed. As a nickel-based alloy, it has great strength at sub-freezing temperatures. This metal alloy is also known as CW-6MC in its cast grade and N06625 in its wrought form.

  • Typical Uses

    Chemical and food processing equipment, nuclear, heat exchangers, combustor/exhaust, shaft sleeves.

  • MetalTek Grade

    MTEK 625
