What are UNS and W.Nr.?

Confused by alloy designations like Inconel 600, UNS N06600, and W.Nr. 2.4816? You’re not alone. It’s common for the same high-performance alloy to have multiple designations from different standards organizations (like UNS) or specific trade names (like Inconel). This can make material selection confusing.

This guide clarifies these specifications. We’ll break down what each designation means and provide a comprehensive nickel alloy grade comparison table to help you easily cross-reference materials and find the exact equivalent you need.
