产品名称

NIMONIC 80A

没有此类产品
产品描述
A nickel-chromium alloy similar to NIMONIC alloy 75 but made precipitation hardenable by additions of aluminum and titanium. The alloy has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 1500°F (815°C). Used for gas-turbine components (blades, rings and discs), bolts, tube supports in nuclear steam generators, die-casting inserts and cores, and exhaust valves in internal-combustion engines.
STANDARD PRODUCT FORMS
Sheet, round bar, flat bar, forging stock, hexagon, wire,
extruded section and plate.
