Aung Metals, a reputable manufacturer and supplier located in Naypyidaw, Myanmar, is known for crafting top-notch Hastelloy Rectangular Bars that stand out for their remarkable corrosion resistance, strength, and durability. By employing cutting-edge manufacturing methods and rigorous quality control, Aung Metals guarantees that each Hastelloy Rectangular Bar adheres to international standards, ensuring reliable performance even in the toughest industrial settings. These bars are celebrated for their exceptional resistance to both oxidizing and reducing chemicals, high temperatures, and extreme operational conditions, making them perfect for industries like chemical, petrochemical, marine, and power generation. Aung Metals delivers precision-engineered Hastelloy solutions that blend toughness, reliability, and long-lasting performance.
Hastelloy Rectangular Bars are mainly made up of nickel (around 57%), molybdenum (approximately 16%), iron (about 6%), and cobalt (roughly 2.5%), along with trace elements of manganese, silicon, and carbon. This unique composition grants them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, all while maintaining impressive mechanical strength. In terms of mechanics, these bars boast a tensile strength ranging from 620 to 860 MPa, yield strength between 200 and 450 MPa, and an elongation of 30 to 50%. They also showcase excellent ductility, fatigue resistance, and weldability, making them ideal for high-performance applications in chemically aggressive and high-temperature environments.
