ASTM B408 Round Bar

Astm B408 Round Bar

ASTM B608 Round Bar is extremely resistant to corrosion, even in acidic environment. Alloy 800HT Rods is particularly useful for high-temperature equipment in the petrochemical industry because the alloy doesn't form the embrittling sigma phase after long time exposure at 1200 Degree F (649 Degree C).These Nickel 800 Round Bars are used for Heat exchangers, Pressure vessels, Dampers, Nitric acid catalyst supports, Reformer outlet pigtails and manifold, and more. ASTM B408 Round Bars are used for process piping, heat exchangers, heating-element sheathing, carburizing equipment, and nuclear steam-generator tubing etc.

Scope And Manufacturing

ASTM B408 specification covers UNS N08800 in the form of hot-worked and cold-worked round bar. Alloy UNS N08800 is normally employed in service temperatures up to and including 1100°F (593°C). The material shall be subjected to heat treatment, and its composition shall conform to the chemical requirements for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, niobium, tantalum, phosphorus, tungsten, cobalt, nitrogen, and boron. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation.
