Anucha Metals is a renowned manufacturer and supplier of hastelloy forgings, with its headquarters in Bangkok, Thailand. Renowned for making high-quality corrosion-resistant and heat-resistant alloy forgings, Anucha Metals caters to industries that need long-lasting and dependable components. The hastelloy forgings at Anucha Metals are designed according to stringent global standards and widely employed in chemical processing, aerospace, power generation, and marine environments. With dedication to accuracy, quality assurance, and punctual delivery, Anucha Metals established a solid reputation as a reliable supplier of high-quality hastelloy materials to both domestic and international markets.
Hastelloy forgings are essentially nickel-based alloys containing large percentages of molybdenum, chromium, and iron, which give excellent resistance to severe chemical environments, such as oxidizing as well as reducing agents. The forgings have excellent mechanical characteristics in terms of high strength, toughness, and resistance against creep and fatigue under high temperatures. Hastelloy forgings also exhibit excellent weldability and can be shaped into intricate forms without sacrificing their corrosion resistance or integrity.

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 the critical parts of chemical reactors, heat exchangers, valves, and pressure vessels where there is frequent exposure to corrosive chemicals and hostile temperatures. They are also critical in aerospace and power generation industries for the application in turbine components, exhaust systems, and nuclear reactor components. Additionally, these forgings find application in marine environments for seawater handling equipment and pollution control equipment, providing long-term performance in harsh environmental and mechanical stresses.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
