Definition of ASTM B637 Inconel 718 Alloy Round Bar
Inconel 718 alloy round bars conforming to ASTM B637 are precipitation-hardening nickel-chromium-based superalloy bars designed for high-strength, corrosion-resistant, and high-temperature (up to 700°C/1300°F) applications. These alloy bars, conforming to ASTM B637, are widely used in the aerospace, gas turbine, and oil/gas industries for manufacturing components requiring superior tensile strength and creep rupture strength.
What are the ASTM standards for Inconel 718 round bars?
Inconel 718 round bars can withstand temperatures up to 1300°F (700°C). They are used in power generation and in the manufacture of engine pistons and pump shafts. Typical specifications are AMS 5662 and ASTM B637. Please be sure to request the EN 10204/3.1B certification for this material from your supplier.
ASTM B637 round bars are a precipitation-hardening nickel-based superalloy that combines excellent corrosion resistance and strength with good weldability. This superalloy contains a large number of alloying elements, such as molybdenum, cobalt, carbon, silicon, manganese, titanium, aluminum, and boron. These round bars are renowned for their high tensile strength, impact strength, fracture strength, and excellent weldability.
