George Metals, based in Houston, USA, stands out as a leading manufacturer and supplier of Hastelloy B2 Forgings, designed to excel in highly aggressive chemical environments. This nickel-molybdenum alloy is renowned for its exceptional resistance to hydrochloric acid, hydrogen chloride, and other potent reducing agents. At George Metals, we offer a diverse array of forged components, including rings, shafts, blocks, discs, and custom shapes, all crafted to meet ASTM B564 specifications. Our precision-forged products find their place in chemical processing, pharmaceuticals, petrochemicals, and waste treatment applications, where top-notch corrosion resistance and mechanical strength are essential for lasting reliability.
Hastelloy B2 Forgings from George Metals are mainly made up of nickel (the balance) and 26–30% molybdenum, with minimal amounts of iron, carbon, silicon, and chromium to reduce carbide precipitation and intergranular corrosion. These forgings boast a tensile strength of around 760 MPa, a yield strength of about 310 MPa, and impressive ductility and impact resistance. Typically provided in a solution-annealed state, Hastelloy B2 retains excellent formability and weldability. At George Metals, we ensure that each forging undergoes rigorous quality testing, ultrasonic inspection, and chemical analysis to guarantee optimal performance in corrosive and high-temperature settings.
