Hastelloy B3 is a nickel-molybdenum alloy that mainly consists of about 65% nickel and 28–30% molybdenum, along with small amounts of iron, cobalt, and trace elements like carbon, silicon, and manganese. This alloy is specifically engineered to withstand hydrochloric acid and other potent reducing agents. It offers enhanced thermal stability compared to B2 and is less sensitive to fabrication processes. In terms of mechanical properties, Hastelloy B3 Bars and Rods boast a tensile strength of around 760 MPa, a yield strength of approximately 350 MPa, and an elongation of about 40%. The alloy retains excellent formability, ductility, and strength even after welding or exposure to high temperatures.
