Sahil Metals is a Riyadh, Saudi Arabia-based leading manufacturer and supplier of high-performance metal solutions for heavy industrial applications. The company supplies a comprehensive selection of **Hastelloy forgings**, which are engineered to meet the most severe chemical corrosion and high-stress conditions. With service to industries including chemical processing, marine, pharmaceutical, and power generation, Sahil Metals offers precision-engineered forgings of international quality standards. Instructed by durability, precision, and timely delivery, Sahil Metals is a reliable partner for forged components employed in severe and corrosive service conditions.
Hastelloy forgings consist of nickel-chrome alloys like C22, C276, B2, and B3, which have varying combinations of corrosion resistance, toughness, and strength. Hastelloy forgings are primarily composed of chromium, molybdenum, iron, cobalt, and tungsten in some proportions. The forgings provide a high tensile strength of (690–800 MPa), good pitting, crevice corrosion, and stress corrosion cracking resistance. Their mechanical soundness does not waver even with exposure to hot temperatures and hostile chemical environments, making them the best for heavy industrial applications where structural integrity and resistance to corrosion are paramount.

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 application in applications where parts undergo extreme chemical exposure and mechanical loading. Some common uses include flanges, valve bodies, fittings, heat exchanger components, reactor vessels, and pump housings. Hastelloy forgings are best suited for hydrochloric acid and sulfuric acid systems, chlorine-containing compounds, and seawater systems. Their high resistance to localized corrosion and uniform corrosion guarantees extended service life with minimal downtime and higher reliability in harsh environments. Plant operators and engineers use Hastelloy forgings for important facilities that require performance, safety, and corrosion resistance during hostile operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
