Dhruv Metals, a well-respected manufacturer and supplier based in Hyderabad, India, specializes in high-quality Alloy 20 Round Bars that are celebrated for their outstanding corrosion resistance and mechanical strength. 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. Dhruv Metals is committed to ensuring that every Alloy 20 Round Bar adheres to strict quality standards, providing precision and reliability for even the most demanding applications. With a strong emphasis on customer satisfaction, the company offers tailored solutions and prompt delivery to clients in the chemical, pharmaceutical, food processing, and marine sectors, both domestically and internationally.
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 known for their exceptional resistance to acid attacks, particularly from sulfuric acid. Alloy 20 boasts a tensile strength of about 551 MPa, a yield strength of 241 MPa, and an elongation of approximately 30–35%. Additionally, the alloy is recognized for its good fabricability, high resistance to pitting and crevice corrosion, and impressive mechanical performance in tough industrial settings.
