Neith Metals, located in Cairo, Egypt, stands out as a top manufacturer and supplier of high-performance specialty alloys and metal products. One of their standout offerings is Hastelloy Forgings, which are celebrated for their remarkable corrosion resistance, impressive strength, and durability, especially in harsh chemical and high-temperature settings. Crafted with cutting-edge forging techniques and rigorous quality control, these forgings adhere to international standards for precision, reliability, and performance. Neith Metals caters to various industries, including chemical processing, petrochemical, marine, and power generation, providing robust Hastelloy Forgings that are engineered for long-term operational efficiency, exceptional mechanical properties, and consistent performance in challenging industrial environments.
Hastelloy Forgings are nickel-based alloys, primarily made up of nickel, molybdenum, and chromium, with small amounts of iron, cobalt, and carbon added to boost their mechanical properties and corrosion resistance. These forgings showcase impressive tensile strength, typically falling between 550–750 MPa, and a yield strength of around 240–350 MPa. With outstanding hardness, toughness, and resistance to pitting, crevice corrosion, and both oxidizing and reducing environments, Hastelloy Forgings maintain their structural integrity even under extreme chemical and high-temperature conditions, making them perfect for critical, high-performance applications.

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.
These Hastelloy Forgings find extensive use in industries that demand high corrosion resistance, strength, and durability. They’re perfect for chemical reactors, heat exchangers, piping systems, valves, pumps, and storage tanks that come into contact with aggressive acids and oxidizing agents. The petrochemical and pharmaceutical sectors rely on these forgings for components that must withstand highly corrosive environments. In marine and offshore applications, Hastelloy Forgings are used for components exposed to seawater and structural parts. Moreover, the power generation and industrial machinery industries depend on these forgings to ensure long-lasting reliability and performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
