Hastelloy B3 Fasteners

Hastelloy B3 fasteners are comprised of a nickel-molybdenum alloy that is known for its high resistance to severe reduction agents. These fasteners maintain stability across varying temperatures and offer high ductility. The chemical composition includes a minimum of 65% nickel, 27–32% molybdenum, and controlled amounts of iron, chromium, and other elements. Mechanical qualities include a tensile strength of 760 MPa, a yield strength of 350 MPa, and an elongation of 40%, making them both strong and flexible. Metracore Alloys is one of the trusted Hastelloy B3 fastener manufacturers in India, and produces these components with precision to meet global quality standards.

Hastelloy B3 Fasteners, Hastelloy B3 Fasteners Manufacturers, Hastelloy B3 Fasteners Manufacturers In India, Hastelloy B3 Fasteners Suppliers

We provide fasteners in a wide range of diameters, from 3 mm to 200 mm, and lengths ranging from M02 to M33. They are available in many forms, such as Hastelloy B3 bolts, nuts, screws and washers, designed to give exceptional performance in demanding situations. It is resistant to hydrochloric acid, has improved thermal stability and has good mechanical strength even under stress. Their durability makes them reliable for use in demanding industries.

Our Hastelloy B3 fasteners are used in chemical processing plants, where resistance to strong acids is critical. They are also common in marine, power generation, and pharmaceutical equipment. These fasteners hold up well in conditions where other alloys fail, especially in high-temperature and high-pressure setups. The manufacturing process involves careful alloy selection, precision machining, and strict testing to ensure consistent quality and performance.
