Starc Metals is a well-respected manufacturer and supplier located in Canberra, Australia, with a focus on high-quality Hastelloy Forgings. The company has built a reputation for crafting durable, corrosion-resistant forged components that meet the rigorous demands of various industrial sectors. Thanks to their cutting-edge forging technology and strict quality control measures, Starc Metals guarantees that each product delivers exceptional mechanical strength, precision, and long-lasting reliability. Their Hastelloy Forgings are specifically engineered to excel in harsh chemical and high-temperature environments, solidifying Starc Metals’ status as a trusted name in the global alloy manufacturing scene.
Hastelloy Forgings are mainly made up of nickel, molybdenum, and chromium, with small amounts of tungsten, cobalt, and iron added to boost their resistance to corrosion and oxidation. These forgings showcase impressive tensile and yield strength, outstanding ductility, and remarkable toughness. They also provide excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in highly oxidizing and reducing conditions. The fine-grain structure of the alloy ensures mechanical stability and reliability in high-temperature and high-pressure settings.

To improve the surface finish of Hastelloy forgings, use techniques like polishing, grinding, or shot peening. Additionally, chemical or electrochemical cleaning can remove surface contaminants and enhance smoothness.
The most suitable forging techniques for Hastelloy include open-die forging and closed-die forging, which ensure optimal material flow and minimize defects. These methods provide the necessary strength and precision for high-performance applications.
To determine if Hastelloy forgings meet your needs, evaluate their chemical composition, mechanical properties, and corrosion resistance in your specific operating conditions. Conduct material testing or consult with suppliers for tailored solutions based on your application requirements.
Hastelloy Forgings find extensive applications in industries like chemical processing, marine, aerospace, power generation, and oil and gas. They are perfect for creating flanges, shafts, rings, fittings, and pressure vessel components that are exposed to corrosive chemicals and extreme temperatures. Additionally, these forgings are used in reactors, heat exchangers, pollution control equipment, and scrubbers. Their outstanding corrosion resistance and mechanical strength make Hastelloy Forgings the go-to choice for environments where reliability, safety, and long-term durability are essential for operational success.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
