Product Description
Alloy Overview
MGA 1400 (commonly referenced in directional solidification processing as DS MGA 1400) is a high-performance, nickel-base superalloy specifically engineered for land-based industrial power-generation gas turbines and high-stress aerospace engine components.
When cast via Directional Solidification (DS), MGA 1400 forms elongated columnar grain structures parallel to the main stress axis, eliminating transverse grain boundaries. This gives the material superior thermal fatigue resistance, high-temperature creep strength, and excellent oxidation/sulfidation resistance in severe operating environments exceeding $1000^circtext{C}$ ($1832^circtext{F}$).
