Isis Metals, a top-notch manufacturer and supplier located in Manila, Philippines, specializes in high-quality Alloy 20 Round Bars that are renowned for their outstanding corrosion resistance and durability. Crafted with cutting-edge metallurgical techniques and premium raw materials, these round bars consistently perform well even in tough chemical and industrial settings. Isis Metals is committed to rigorous quality control and compliance with international standards, ensuring that their products are reliable and precise for critical applications. Alloy 20 Round Bars are perfect for industries like chemical, petrochemical, pharmaceutical, and food processing, where resistance to sulfuric acid, chloride stress corrosion, and oxidizing agents is crucial for long-lasting, high-performance components.
Alloy 20 Round Bars mainly consist of nickel (32–38%), chromium (19–21%), and copper (3–4%), along with molybdenum (2–3%) and small amounts of iron and carbon. This specific blend guarantees excellent resistance to both oxidizing and reducing acids, particularly sulfuric acid. The alloy boasts a tensile strength of up to 655 MPa, a yield strength of around 275 MPa, and an elongation of 35%. Alloy 20 is known for its superior toughness, ductility, and weldability, maintaining its mechanical integrity and dimensional stability even in high-stress, corrosive environments, making it ideal for critical industrial components and applications.
