Aung Metals, a prominent manufacturer and supplier located in Naypyidaw, Myanmar, is committed to crafting and delivering top-notch alloy steel products, including the highly sought-after 20MnCr5 Round Bars. With state-of-the-art manufacturing facilities and a strong focus on international quality standards, Aung Metals ensures that their materials deliver outstanding performance, durability, and precision. They serve a diverse array of industries, from automotive and engineering to machinery and power generation. Known for their reliability and technical know-how, Aung Metals consistently provides 20MnCr5 Round Bars that meet the rigorous demands of modern industrial applications, both in Myanmar and beyond.
20MnCr5 Round Bars are low-alloy case-hardening steels that contain about 0.17–0.22% carbon, 1.1–1.4% manganese, 0.9–1.2% chromium, along with trace amounts of silicon and sulfur. This specific blend strikes a perfect balance between core toughness and surface hardness after the carburizing process. The material boasts impressive mechanical properties, featuring a tensile strength ranging from 550 to 850 MPa, along with good ductility and high wear resistance. 20MnCr5 holds its structural integrity even under stress, making it an excellent choice for components that need both a hard surface and a resilient core to enhance fatigue performance.
