Aung Metals, a top-notch manufacturer and supplier located in Naypyidaw, Myanmar, is all about crafting high-quality Hastelloy Forgings that stand out for their incredible corrosion resistance, strength, and durability. Thanks to cutting-edge forging techniques and rigorous quality control, Aung Metals guarantees that each Hastelloy Forging not only meets international standards but also performs reliably in the toughest industrial settings. Known for their remarkable ability to resist both oxidizing and reducing chemicals, as well as high temperatures and extreme conditions, these forgings are perfect for industries like chemical, petrochemical, marine, and power generation. Aung Metals delivers precision-engineered Hastelloy solutions that blend toughness, reliability, and long-lasting performance.
Hastelloy Forgings are mainly made up of nickel (about 57%), molybdenum (around 16%), iron (approximately 6%), and cobalt (about 2.5%), along with small amounts of manganese, silicon, and carbon. This unique composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, all while maintaining impressive mechanical strength. In terms of mechanics, Hastelloy forgings boast a tensile strength ranging from 620 to 860 MPa, yield strength between 200 and 450 MPa, and an elongation of 30 to 50%. The material also showcases excellent ductility, fatigue resistance, and weldability, making it a go-to choice for high-performance applications that are chemically aggressive and high-temperature.

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 their place in various sectors, including chemical, petrochemical, marine, pharmaceutical, and power generation, thanks to their superior corrosion resistance and mechanical properties. Common applications include reactor vessels, pressure vessels, heat exchangers, pumps, valves, fasteners, and piping systems that come into contact with highly corrosive chemicals and extreme temperatures. They’re also utilized in offshore platforms, desalination plants, and chemical processing units where durability, safety, and reliability are paramount. With Hastelloy Forgings, you can expect long-lasting performance, operational efficiency, and structural integrity.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
