Hastelloy B3 round bar is a high-performance nickel-molybdenum alloy known for its excellent resistance to hydrochloric acid and other aggressive chemicals. It remains strong even in extreme environments, making it an excellent choice for chemical processing. Preston Pipes & Alloys is one of the leading Hastelloy B3 round bar suppliers, offering premium-quality bars to meet demanding industrial needs. This alloy contains nickel, molybdenum, chromium, iron, tungsten, manganese, carbon, aluminum, titanium, and silicon. These elements together provide strong mechanical strength, high thermal stability, and superior corrosion resistance. With a density of 9.2 g/cm³ and a melting point of 1370°C, the Hastelloy B3 bar delivers a tensile strength of 115,000 psi and a yield strength of 52,000 psi, along with 40% elongation, making it both tough and flexible under pressure.
We supply Hastelloy B3 round bar as per ASTM B335 / ASME SB335 specifications. The bars range in size from 6 mm to 120 mm and are available in round, square, hexagonal, and rectangular shapes. Standard dimensions follow ASTM, ASME, and API requirements, with lengths ranging from 100 mm to more than 3000 mm. Each bar is finished to fit the unique application requirements, such as bright, polished or black finishes. Whether you want unique lengths or specific measurements, our production techniques guarantee consistent quality, and accuracy in each bar.
These bars offer high resistance to thermal cracking, pitting, and stress corrosion. That makes them perfect for industries like chemical processing, pharmaceuticals, power generation, and marine applications. Hastelloy B3 round bar is often used in heat exchangers, pressure vessels, reactors, and piping systems exposed to acidic conditions. Its stability under thermal cycling and excellent fabricability give it an edge in high-temperature and corrosive settings. It also resists oxidation, which adds to its long service life.
Each Hastelloy B3 round bar is subjected to stringent quality control checks before shipment. To fulfill industry standards, we undertake various tests such as tensile strength testing, ultrasonic inspection, and PMI. Bars are packed with care using wooden crates or bubble wraps to prevent damage during transit. Our goal is to deliver high-quality, tested material that performs well.
