Alloy 20 forged products are highly sought after for their exceptional resistance to corrosion, especially in acidic environments. Known for its superior performance in chemical and pharmaceutical industries, Alloy 20 is an iron-based austenitic material composed of nickel, chromium, molybdenum, and copper. It provides an excellent balance of strength, resistance to pitting, and superior stress corrosion cracking resistance.

Alloy 20 is particularly designed to withstand harsh environments, including sulfuric acid, phosphoric acid, nitric acid, and other corrosive media. The alloy’s high nickel content (about 35-40%) contributes to its excellent resistance to chloride-induced stress corrosion cracking. Additionally, it has high strength and thermal stability, making it a reliable choice for a variety of critical applications. When used in forged products, these properties are enhanced, ensuring long-lasting durability and reduced maintenance costs in systems where equipment is exposed to extreme conditions.
Alloy 20 forged products are used across various industries, with chemical processing being one of the most significant sectors. The resistance to sulfuric acid makes it ideal for the production of pressure vessels, tanks, and piping systems. In the food and beverage industry, Alloy 20 is used for manufacturing equipment that must be resistant to acid attacks. Similarly, pharmaceutical manufacturers rely on Alloy 20 forged products due to their ability to endure harsh cleaning and sterilization procedures. Other sectors include the aerospace and marine industries, where corrosion resistance and mechanical properties are critical.
When sourcing Alloy 20 forged products, it is crucial to select reliable importers and suppliers who can provide high-quality materials with the proper certifications. Leading suppliers ensure that the materials meet international standards such as ASTM, ASME, and DIN, ensuring consistent quality and performance. Importers bring Alloy 20 forged products from reputable manufacturers, offering a wide range of sizes and customizations for specific industry requirements.
Trusted suppliers work closely with customers to deliver precise forged products that meet the exact specifications needed for various applications.
