Nr. 2.4952 TTaabbllee 11 - Limiting Chemical Composition, % by Weight 2.4631) is a wrought, age-hardenable nickel-chromium Carbon0.10 max. alloy, strengthened by additions of titanium, aluminum Chromium18.0-21.0 and carbon, developed for service at temperatures up to Silicon 1.0 max 815°C (1500°F). It is produced by high-frequency Copper0.2 max. melting and casting in air for forms to be extruded. Iron3.0 max. Electroslag refined material is used for forms to be Manganese 1.0 max. forged. Vacuum refined versions are also available. Titanium1.8-2.7 NIMONIC alloy 80A is currently used for gas turbine Aluminum 1.0-1.8 components (blades, rings and discs), bolts, nuclear Cobalt 2.0 max. boiler tube supports, die casting inserts and cores, and Boron 0.008 max. for automobile exhaust valves.
