Semih Metals, based in Istanbul, Turkey, is a trusted name in the manufacturing and supply of Monel Forgings. They specialize in high-quality nickel-copper alloy components that are celebrated for their strength, durability, and remarkable resistance to corrosion. Crafted with precision and a commitment to global standards, these forgings boast excellent dimensional accuracy, outstanding mechanical stability, and reliable performance even in the harshest conditions. Semih Metals guarantees that its Monel Forgings meet the rigorous demands of industries like marine, oil and gas, aerospace, and chemical processing, where components must withstand aggressive environments, high stress, and long service life.
Monel Forgings mainly consist of nickel (around 63%) and copper (approximately 28–34%), along with trace amounts of iron, manganese, carbon, and silicon. This distinctive blend offers exceptional resistance to seawater, acids, alkalis, and other corrosive substances while ensuring high mechanical strength. Monel alloys, including Monel 400 and Monel K500, are known for their excellent toughness, ductility, and resistance to stress corrosion cracking and erosion. The forging process enhances the material’s grain structure, boosting its strength and fatigue resistance, making it ideal for critical and high-performance applications.

The forging process for Monel typically takes several hours, depending on the size and complexity of the component. It involves heating, shaping, and cooling, with each stage carefully controlled to ensure quality.
The most suitable forging techniques for Monel alloys include open-die and closed-die forging. These methods ensure precise shaping and maintain the material's strength and corrosion resistance during the process.
These Monel Forgings find their place in industries where top-notch corrosion resistance and mechanical strength are essential. They’re commonly used in marine components like shafts, propellers, and seawater valves, as well as in oil and gas drilling equipment, pumps, and fasteners. In aerospace, they are utilized in turbine engine parts and landing gear components, while the chemical processing sector employs them in heat exchangers, reactors, and piping systems. Thanks to their exceptional durability and performance, Monel Forgings are the go-to choice for demanding industrial, marine, and aerospace environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
