Anucha Metals stands out as a top manufacturer and supplier located in Bangkok, Thailand, focusing on high-performance metal products like Alloy 20 Round Bars. Renowned for their quality, precision, and reliability, Anucha Metals caters to a variety of industries, including chemical processing, pharmaceuticals, and marine engineering. With a strong dedication to customer satisfaction, they offer Alloy 20 round bars in multiple sizes and specifications that comply with both local and international standards. Their cutting-edge manufacturing facility and rigorous quality control processes guarantee products that boast exceptional durability and resistance, establishing Anucha Metals as a trusted name in both the Thai and global metal markets.
Alloy 20 Round Bar is primarily made up of nickel (32-38%), chromium (19-21%), iron (the balance), along with molybdenum (2-3%), copper (3-4%), and columbium for stabilization. This composition provides excellent corrosion resistance, particularly in sulfuric acid environments. Its mechanical properties include a minimum tensile strength of 551 MPa, a minimum yield strength of 241 MPa, and an elongation of 30%. The bar is non-magnetic and retains its strength and ductility across a wide temperature range, making it perfect for demanding industrial applications.

Alloy 20 Round Bars find extensive use in the chemical processing industry due to their outstanding corrosion resistance, especially against sulfuric acid. You’ll often see them in heat exchangers, mixing tanks, process piping, and valves within pharmaceutical, food and beverage, and petrochemical plants. They’re also well-suited for marine environments, where they resist chloride-induced stress corrosion cracking. Power generation facilities and plastic manufacturing plants depend on Alloy 20 for its mechanical strength and chemical stability. Its excellent weldability and machinability make it a go-to choice for engineers.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
