Low Cost, Multipurpose Alloy. Tensile/toughness property data below for Beta Forged, RA material.

Features: Properties and processing characteristics equivalent to or better than TIMETAL 6-4, but with significantly higher stiffness (elastic modulus). Due to the use of iron as the beta stabilizer, the alloy has lower formulation costs than TIMETAL 6-4. The combination of reasonable cost and excellent mechanical properties make TIMETAL 62S a practical substitute for many engineering materials.

Typical heat treatment for this alloy: Mill Anneal at 760°C for 1-2 hrs, air cool
