High Temperature Alloy Nimonic80A Wire For Manufacture Of Bolts
Nimonic80A High Temperature Nickel Alloy
Alloy 80A (Nimonic alloy 80A) is a wrought, age-hardenable nickel-chromium alloy. Alloy 80A is similar to alloy75 but made precipitation hardenable by additions of aluminium and titanium. Alloy 80A has good corrosion and oxidation resistance and high tensile and creep-rupture properties at temperatures to 815ºC (1500ºF). Vacuum refined versions are also available. Alloy 80A is used for gas-turbine components (blades, rings, discs), bolts, tube supports in nuclear generators, exhaust valves in internal combustion engines and has many other offshore/marine, automotive and electrical applications.
Application: Ships, tanks with diesel exhaust valve mainly made of wrought Nimonic 80A. Nimonic 80A has high heat resistance, high strength at high temperatures, deformation resistance, increasing the difficulty of forging suitable for the manufacture of bolts, combustion chamber exhaust valve.
