Semih Metals, based in Istanbul, Turkey, is a leading manufacturer and supplier of high-quality metals. One of their specialized products is Alloy 20 Forgings. Alloy 20 is a nickel-iron-chromium alloy known for its excellent resistance to corrosion, especially against acids. The forging process makes the material stronger and more reliable for industrial use. Semih Metals ensures that every Alloy 20 Forging meets international quality standards. These forgings are widely used in industries where strength and resistance to harsh chemical environments are important. Customers can trust Semih Metals for consistent quality and timely delivery..
Alloy 20 Forgings are mainly made of nickel, iron, and chromium, with small amounts of copper and molybdenum. This combination makes the material strong, tough, and highly resistant to corrosion, especially from sulfuric acid. The forging process improves its mechanical properties, giving it high tensile strength, good hardness, and excellent durability. Alloy 20 Forgings can handle high pressure and temperature without deforming. Semih Metals ensures that each forging is produced with uniform composition and tested for strength and corrosion resistance, providing reliable performance for industrial applications.
