Hastelloy B2 round bar is a solid solution-strengthened nickel-molybdenum alloy with exceptional resistance to reducing conditions such as hydrochloric acid, and hydrogen chloride gas. Preston Pipes & Alloys is a known name in the market delivering excellent Hastelloy B2 bars to numerous sectors and providing continuous quality and performance. It consists of important elements such nickel, molybdenum, chromium, iron, manganese, carbon, phosphorus, sulfur and silicon, which combined provide outstanding performance in harsh media. The alloy offers high tensile and yield strength along with good elongation. With a density of 9.2 g/cm³ and a melting point of 1370°C, this material stands up well in extreme conditions.
These bars are manufactured in round, square, hex, and rectangular forms, with sizes ranging from 6 mm to 120 mm. Lengths commonly range from 100 mm to 3000 mm and up, with finishes available in bright, polished, and black. Hastelloy B2 round bars conform to global standards such as ASTM, ASME and API and are produced by precision-controlled procedures such as hot rolling and cold drawing. This ensures the bars meet exact dimensional and surface finish requirements, offering strength and reliability across all batches.
Hastelloy B2 bars are favored for their strong resistance to pitting, stress corrosion cracking, and knife-line attack. Their ability to perform in highly corrosive settings makes them ideal for applications in chemical processing, power plants, marine equipment, and pollution control systems. The bars also resist thermal cracking and keep their strength at high temperatures, making them appropriate for use in heat exchangers, pressure vessels and reactor vessels.
Every bar undergoes strict quality checks to such as hardness tests, tensile tests, PMI and dimensional checks. As a hastelloy b2 round bar suppliers, we pack every order with care using wooden boxes, plastic wrapping, and proper labeling to prevent surface damage or contamination during transport. Choose high-grade Hastelloy B2 round bars for demanding industrial use with confidence.
