Incoloy 800/825 Hex Bars are high-performance nickel-iron-chromium alloys designed to withstand extreme temperatures and corrosive environments. These hexagonal bars are widely used in chemical, petrochemical, and power generation industries due to their excellent resistance to oxidation and carburization. The alloy composition ensures a perfect balance of strength and durability, making them suitable for heat exchangers, furnace parts, and pressure vessels. Incoloy 800/825 Hex Bars maintain structural integrity even under thermal cycling conditions. Their mechanical properties allow them to sustain high loads without significant deformation. The precision in manufacturing guarantees uniform dimensions and surface finish. This makes them a preferred choice for critical applications.

The chemical composition of Incoloy 800/825 Hex Bars typically includes nickel, chromium, and iron, with small amounts of carbon, manganese, silicon, and copper. Nickel provides high-temperature strength and resistance to corrosion, while chromium enhances oxidation resistance. Iron ensures cost-effectiveness while maintaining structural stability. Carbon content is controlled to reduce the risk of sensitization, preventing intergranular corrosion. Additional elements like copper in Incoloy 825 improve resistance to reducing acids such as sulfuric acid. The combination of these elements gives the alloy its exceptional versatility. Each hex bar undergoes strict quality checks to meet international standards.

Incoloy 800/825 Hex Bars offer remarkable mechanical properties that make them ideal for demanding industrial environments. The yield strength typically ranges between 215–275 MPa, and the tensile strength is about 515–690 MPa. These bars have good elongation, around 30–40%, which ensures toughness under stress. Hardness usually falls between 160–190 HB, providing wear resistance for long-term service. They also exhibit excellent creep and fatigue resistance at elevated temperatures. The alloy’s thermal stability ensures minimal scaling and distortion under high-heat operations. This makes Incoloy 800/825 Hex Bars suitable for both static and dynamic structural components.
