Chuck Metals is a reputable manufacturer and supplier of Hastelloy B2 Bars and Rods in Singapore, catering to high-performance industries throughout Pulau Ujong with their corrosion-resistant and durable alloy solutions. These Hastelloy B2 bars and rods are well-known for their outstanding resistance to hydrochloric acid, impressive thermal stability, and robust mechanical strength, making them perfect for harsh chemical service environments. Crafted to meet standards like ASTM B335, these bars come in various sizes and finishes, ideal for both precision machining and structural applications.
Hastelloy B2 is a nickel-molybdenum alloy that mainly consists of 69–71% nickel and 26–30% molybdenum, with only trace amounts of iron and chromium. It boasts tensile strengths of about 760 MPa and yield strengths around 345 MPa, along with remarkable resistance to hydrogen chloride gas, sulfuric acid, and acetic acid. This alloy retains its ductility and formability even after welding, and it effectively resists grain-boundary carbide precipitation.

Yes, Hastelloy B2 rods can be welded. However, it requires proper techniques and filler materials to avoid cracking due to their sensitivity to heat-affected zones.
Hastelloy B2 bars offer exceptional resistance to hydrochloric acid and other corrosive environments, along with excellent weldability and high strength. They are highly resistant to pitting, stress corrosion, and localized corrosion.
Hastelloy B2 rods are available in various sizes, ranging from small diameters to larger rods, with common diameters including 0.125 inches to 4 inches. They typically come in a polished or cold-drawn finish, depending on the application requirements.
Hastelloy B2 bars and rods find extensive use in industries such as chemical processing, pharmaceuticals, pulp and paper, marine, and nuclear. Common applications include pump shafts, valves, reactor vessels, heat exchanger components, and agitators that are exposed to aggressive chemical environments. Their reliability in extreme corrosive and thermal conditions makes them the go-to choice for critical, long-lasting applications where other alloys might not hold up.
