ASTM B637 Round Bar

Astm B637 Round Bar

ASTM B637 Round Bar is a precipitation hardening nickel super alloy that combines superior corrosion resistance and strength with high weldability. This super alloy contains significant levels of carbon, manganese, silicon, phosphorus, sulfur, chromium, cobalt, molybdenum, columbium, tantalum, titanium, aluminum, zirconium, boron, iron, copper, and nickel. Known for their rupture, high tensile and impact strength, Inconel 718 bars also allows for superior weldability. Additionally, this super alloy can be used in a wide range of temperatures—as Inconel 718 is capable of withstanding the intense demands of extreme cold and heat. These qualities make Inconel 718 rods a popular choice for numerous industries. The alloy is ideal for hot extrusion tooling and parts, such as: casings, bolts, fasteners, rings and instrumentation components. Inconel 718 bars are also frequently used in fabricating aerospace, aircraft and other components.

Scope And Manufacturing

ASTM B637 specification covers hot and cold-worked precipitation-hardenable nickel alloy rod, bar, forgings, and forging stock for high-temperature service. Chemical analysis shall be performed on the alloy and shall conform to the chemical composition requirement in carbon, manganese, silicon, phosphorus, sulfur, chromium, cobalt, molybdenum, columbium, tantalum, titanium, aluminum, zirconium, boron, iron, copper, and nickel. The material shall follow recommended annealing treatment, solution treatment, stabilizing treatment, and precipitation hardening treatment. Tension testing, hardness testing and stress-rupture testing shall be performed on the material and shall comply to the required tensile strength, yield strength, elongation, reduction in area, and Brinell hardness.
