Manila, Philippines-based Isis Metals is a reliable producer and supplier of high-quality Hastelloy Forgings to thrive in the most challenging industrial conditions. Known for precision engineering, long-lasting performance, and high-quality corrosion resistance, Isis Metals supplies products that surpass international standards. Our Hastelloy Forgings are produced to provide top-notch performance under elevated pressure, heat, and chemically corrosive conditions, with long-term dependability in high-risk applications. With its emphasis on quality assurance, customer satisfaction, and timely delivery, Isis Metals has established itself as a top choice supplier of choice for clients looking for reliable and high-performance metal solutions.
Hastelloy Forgings are high-performance nickel-based alloys consisting of Nickel, Chromium, and Molybdenum, along with additions of Iron, Tungsten, and Cobalt to provide strength and corrosion resistance. They contain good tensile strength, superior fatigue resistance, and ductility even in harsh temperatures. Hastelloy provides better resistance against pitting, crevice corrosion, and oxidation and is thus suited for aggressive conditions. With great weldability and mechanical stability, Hastelloy Forgings provide extended service life, durability, and low maintenance, retaining structural integrity and performance in high-stress and high-temperature industrial 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.
Hastelloy Forgings have broad applications in industries where materials are exposed to corrosive, high-temperature, and high-pressure conditions. In the chemical process industry, they are employed in the production of valves, pumps, heat exchangers, and reactor vessels operating under exposure to aggressive acids and oxidizing agents. In power generation and aerospace industries, Hastelloy is selected for turbine components, combustion chambers, and exhausts because of its higher strength and oxidation resistance. The petrochemical, marine, and nuclear sectors also depend on Hastelloy forgings for pressure vessel and piping systems, heat treatment equipment, providing long-term reliability and safe operation in the most severe service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
