| Property | Hastelloy Alloy Rods |
| Material Composition | Hastelloy alloys are primarily composed of nickel, molybdenum, chromium, and other alloying elements such as iron, tungsten, and cobalt, depending on the specific grade. Common grades include Hastelloy C-276, Hastelloy C-22, and Hastelloy B-3. |
| Diameter Range | Hastelloy rods are typically available in diameters from 5 mm to over 150 mm, depending on the alloy and intended application. |
| Applications | Used in the production of valves, pump shafts, fasteners, reactor components, heat exchangers, and other critical parts for industries such as aerospace, chemical processing, power generation, and marine environments. |
| Mechanical Properties | High strength, excellent toughness, and fatigue resistance. They maintain their strength and integrity even under high-temperature and high-stress conditions. |
| Corrosion Resistance | Outstanding resistance to a wide range of corrosive environments, including sulfuric, hydrochloric, and phosphoric acids, as well as seawater. Highly resistant to pitting, crevice corrosion, and stress corrosion cracking. |
| Thermal Resistance | Excellent performance at high temperatures, capable of withstanding temperatures over 1000°C (1832°F) without significant degradation in mechanical properties. |
| Forming & Fabrication | Hastelloy rods can be hot-rolled, cold-rolled, or forged, depending on the required mechanical properties. They can be machined, welded, and cut to specific dimensions. |
| Heat Treatment | Hastelloy rods are often heat-treated to enhance mechanical properties like strength and toughness. Solution annealing or stress-relieving heat treatments are common, depending on the alloy and application. |
| Welding & Joining | Hastelloy rods are weldable using techniques like TIG (Tungsten Inert Gas), MIG (Metal Inert Gas), and electron beam welding. Special care is required during welding to prevent material degradation. |
| Examples of Alloys | Hastelloy C-276, Hastelloy C-22, Hastelloy B-3, Hastelloy X, Hastelloy B-2. |
| Cost | More expensive than carbon steel and many other alloys due to the high cost of nickel, molybdenum, and other alloying elements used in the composition. |
| Common Standards | ASTM B574, ASTM B575, ASTM B619, AMS 5580, ASME SB-574. |
