Nickel Alloy

Nickel AISI/SAE

Nickel-based alloys known for exceptional heat and corrosion resistance, widely used in aerospace turbines and chemical processing.

Nickel-based superalloys maintain their strength and corrosion resistance at temperatures where steel and aluminum alloys would fail. Originally developed for jet engine turbine blades in the 1940s, they now serve critical roles in chemical processing, nuclear energy, oil and gas, and pollution control systems.

Designation Guide

Nickel alloys are typically identified by trade names: Inconel (Ni-Cr-Fe for high temperature), Hastelloy (Ni-Mo-Cr for corrosion resistance), Monel (Ni-Cu), and Waspaloy (Ni-Cr-Co-Mo for turbine discs). UNS N-numbers provide standardized designations: N06625 (Inconel 625), N10276 (Hastelloy C-276), N04400 (Monel 400).

Selection Tips

Inconel 625 is the versatile choice for marine, chemical, and aerospace applications up to 800 °C. Inconel 718 (age-hardenable) provides the highest strength for turbine discs and fasteners. Hastelloy C-276 handles virtually any corrosive media below 1,000 °C. Monel 400 is cost-effective for seawater and hydrofluoric acid service. For the most extreme temperatures (>1,000 °C), consider single-crystal superalloys like CMSX-4.
