# Inconel 693

*N06693*

> Advanced Ni-Cr-Al alloy with unparalleled metal dusting resistance for petrochemical reforming.

Inconel 693 is a high-chromium nickel alloy with aluminum designed for the most severe metal dusting and carburization environments. It is the premier material for hydrogen and syngas production plants where CO-rich gas streams cause catastrophic carburization in conventional alloys.
