EIN-286 (UNS S66286): Precipitation-Hardening Alloy für Fasteners zu 700°C

AMS 5731 / ASTM A453 Gr 660 · Published: 2026-06-02 · Updated: July 2026

Quick Reference

A-286 is the standard aerospace fastener alloy for 500-700°C service — where 17-4PH is too weak and Inconel 718 is overkill. Gamma-prime (Ni3(Ti,Al)) precipitation provides strength. For gas turbine bolting, springs, and fasteners. Iron-base =...

EIN-286 ist der standard aerospace fastener alloy für 500-700°C service — wo 17-4PH ist zu weak und Inconel 718 ist overkill. Gamma-prime (Ni3(Ti,Al)) precipitation provides strength. Für gas turbine bolting, springs, und fasteners. Iron-base = fraction von nickel alloy kosten.
