Cnc Machining Inconel 625
Inconel 625 is a superalloy primarily composed of nickel (58% minimum) and chromium (20-23%), with notable additions of molybdenum (8-10%) and niobium (3.15-4.15%). This unique composition imparts exceptional strength and corrosion resistance, even in harsh environments. The alloy’s microstructure consists of a face-centered cubic (FCC) lattice, contributing to its high-temperature stability and resistance to oxidation and carburization.
