K-Monel/K-500, UNS N05500

Alloy 500 is a variant of Alloy 400. The addition of aluminum and titanium, along with a heat-treat process known as age-hardening, creates a much stronger material. Corrosion resistance is similar. It is approved by ASME for bolting applications up to 500° F. Alloy 500 is used extensively in critical marine applications.
