Al Summan Metals, a well-known manufacturer and supplier located in Dubai, UAE, is dedicated exclusively to producing top-quality Alloy 20 Round Bars that are designed to resist corrosion and last for years. By concentrating closely on quality and precision engineering, Al Summan Metals ensures that their products meet international standards, making them well-suited for chemical processing and industrial uses. Their Alloy 20 Round Bars are particularly valued for their exceptional resistance to sulfuric acid and other severe conditions, which positions them as a favored option for challenging applications. Al Summan Metals strives to supply dependable, high-performance materials to customers throughout the chemical, petrochemical, and marine industries, both inside the UAE and abroad.
These Alloy 20 Round Bars consist primarily of nickel (32–38%), iron (making up the balance), chromium (19–21%), copper (3–4%), and molybdenum (2–3%), plus a small amount of niobium for stabilization. This distinctive blend provides them with exceptional resistance to sulfuric acid, pitting, and chloride stress corrosion cracking. Regarding mechanical properties, Alloy 20 delivers a tensile strength of about 620 MPa, a yield strength of 300 MPa, and an elongation of 30–40%. Moreover, it retains excellent ductility and formability, making it a great fit for both high-temperature and corrosive settings.
