Hastelloy X Fasteners

Hastelloy X Fasteners are high-performance alloy fasteners known for their strength and heat resistance. They are made with a balanced mix of nickel, chromium, iron, and molybdenum, with cobalt for added toughness. The chemical composition includes 20.5–23.0% chromium, 17.0–20.0% iron, and 8.0–10.0% molybdenum. It has excellent mechanical properties with a tensile strength of 760 MPa, a yield strength of 350 MPa, and 40% elongation. Metracore Alloys, one of the trusted Hastelloy X fastener manufacturers in India, supplies fasteners with a density of 9.2 g/cm³ and a melting point of 1370 °C.

Hastelloy X Fasteners Manufacturers In India, Hastelloy X Fasteners, Hastelloy X Fasteners Manufacturers, Hastelloy X Fasteners Suppliers

We provide fasteners in sizes ranging from 3 mm to 200 mm and lengths ranging from M02 to M33. We designed it to provide stability under stress and offer a variety of options, including Hastelloy X bolts, nuts, screws, and washers. Their features include high resistance to oxidation, corrosion, and scaling at elevated temperatures, making them a reliable choice for harsh service conditions.
Hastelloy X fasteners are highly valued in industries that face extreme heat and corrosion. They are used in gas turbines and jet engines because they retain strength and resist oxidation even above 1000 °C. In chemical plants, these fasteners hold up against strong acids and aggressive chemicals, making them reliable in reactors and processing units. Power plants use them in boilers, heat exchangers, and pressure vessels where both heat and stress are constant. They are also common in furnace hardware and heat-treatment equipment because they do not crack or scale under repeated thermal cycles.

Hastelloy X Washers, Hastelloy X Bolts, Hastelloy X Screws, Hastelloy X Nuts

These fasteners are supplied in accordance with ASTM B572 requirements and include quality and compliance certifications. We use hardwood boxes, crates, and bubble wrap to protect them against damage during shipment. As reliable Hastelloy X fasteners suppliers, we deliver products tested for durability and performance, offering our customers long-lasting and dependable fastening solutions.
