INCONEL 718 & 718SPF

没有此类产品
产品描述
Inconel alloy 718 is a precipitation-hardenable nickel-chromium alloy also containing significant amounts of iron, niobium and molybdenum along with lesser amounts of aluminum and titanium. It combines corrosion resistance and high strength with outstanding weldability, including resistance to post-weld cracking. The alloy has excellent creep-rupture strength at temperatures to 1300°F (700°C). Used in gas turbines, rocket motors, spacecraft, nuclear reactors, pumps and tooling. INCONEL alloy 718SPF is a special version designed for superplastic forming.
STANDARD PRODUCT FORMS
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging
stock, hexagon, wire and extruded section.
