With state-of-the-art production facilities and rigorous quality control measures, they guarantee excellent dimensional accuracy, a superior surface finish, and reliable mechanical performance. Their customer-centric approach, competitive pricing, and prompt delivery make Mourad Metals a go-to choice for 20MnCr5 round bars, especially in demanding engineering and industrial applications.
20MnCr5 is a low-carbon alloy steel that typically contains around 0.17–0.22% carbon, 1.10–1.40% manganese, and 1.00–1.30% chromium, along with trace amounts of silicon and carefully managed impurities. This precise chemical composition gives the steel remarkable hardenability, making it perfect for carburizing and heat treatment. When in use, 20MnCr5 round bars exhibit high surface hardness after case hardening, impressive core toughness, dependable tensile strength, and strong resistance to wear and fatigue, even under cyclic loading conditions.
