Starc Metals, located in Canberra, Australia, stands out as a top manufacturer and supplier of high-performance alloys, particularly known for their Incoloy 800H forgings. With a reputation built on precision engineering and strict quality control, Starc Metals provides solutions tailored to meet the rigorous demands of sectors like power generation, chemical processing, and aerospace. Their Incoloy 800H forgings are designed to endure harsh environments, showcasing remarkable resistance to oxidation, carburization, and high-temperature corrosion. Committed to reliability, durability, and customer satisfaction, Starc Metals guarantees that every product adheres to international standards, ensuring clients receive exceptional performance and lasting operational efficiency.
Incoloy 800H forgings are made from a nickel-iron-chromium alloy that contains about 30–35% nickel, 19–23% chromium, and 39–46% iron, along with trace amounts of manganese, silicon, and carbon. The high levels of nickel and chromium provide outstanding resistance to oxidation and corrosion at high temperatures. On the mechanical side, Incoloy 800H boasts impressive tensile strength, creep resistance, and toughness even in elevated temperatures, making it perfect for challenging thermal environments. The carefully controlled carbon content improves creep rupture properties while still maintaining ductility. These characteristics make Incoloy 800H forgings a reliable choice for critical industrial applications in extreme conditions.
