Nial Sheets and Plates, located in Houston, USA, is a well-respected manufacturer and supplier of high-performance Alloy 20 Steel Angles, designed to provide corrosion-resistant solutions for tough industrial settings. These Alloy 20 angles are engineered to thrive in highly acidic and chloride-rich environments, making them perfect for structural applications in the chemical, petrochemical, and pharmaceutical sectors. With a reputation for precision fabrication and rigorous quality control, Nial offers Alloy 20 Steel Angles in a variety of sizes and specifications that meet international standards. Their dedication to durability, performance, and customer satisfaction has made Nial a reliable source for long-lasting steel products.
Alloy 20 Steel Angles are primarily made up of nickel (32–38%), chromium (19–21%), and iron (the balance), along with molybdenum (2–3%), copper (3–4%), and trace amounts of manganese, silicon, and niobium. This unique composition grants them outstanding resistance to sulfuric acid, pitting, and chloride stress corrosion cracking. In terms of mechanical properties, they boast a tensile strength of 551–751 MPa, a yield strength of around 241–344 MPa, and an elongation of about 30–35%. Alloy 20 also features good weldability and formability, making it suitable for demanding chemical and marine environments where corrosion resistance and structural integrity are crucial.
