HY Titanium 6-2-4-2 Material grades and equivalents

6Al-2Sn-4Zr-2Mo, 6-2-4-2 Titanium, 6-2-4-2, UNS R54620

Introduction

A near-alpha alloy, primarily used for high strength and toughness, with good creep resistance up to 1000°F. Forging and machining characteristics similar to those of Ti 6Al-4V. Applications include compressor components, hot airframe skin, and engine afterburner structures. The weld ability of Ti 6-2-4-2 is fair, using AMS 4952 weld wire. Several different treatments are available.
