These bars are specifically engineered to thrive in highly corrosive environments, making them a go-to choice for industries that need to withstand sulfuric acid and other harsh chemicals. At Dhruv Metals, every Alloy 20 Round Bar is crafted to meet rigorous quality standards, ensuring precision and reliability for even the most demanding applications. With a strong commitment to customer satisfaction, the company offers tailored solutions and prompt delivery to clients in the chemical, pharmaceutical, food processing, and marine sectors, both in India and around the globe.
Alloy 20 Round Bars are made up of roughly 35% nickel, 20–24% chromium, 3–4% copper, and 2–3% molybdenum, with iron serving as the base element. They also include trace amounts of niobium to help stabilize the alloy and minimize carbide precipitation. These bars are particularly resistant to acid attacks, especially from sulfuric acid. Alloy 20 boasts a tensile strength of about 551 MPa, a yield strength of 241 MPa, and an elongation of roughly 30–35%. Additionally, the alloy is known for its excellent fabricability, strong resistance to pitting and crevice corrosion, and remarkable mechanical performance in tough industrial settings.
