Neith Metals, located in Cairo, Egypt, has earned a solid reputation as a reliable manufacturer and supplier of top-notch 20MnCr5 Round Bars. With a strong focus on precision engineering and ensuring customer satisfaction, Neith Metals provides products that adhere to international standards for strength, durability, and performance. These round bars are popular in the automotive, engineering, and industrial sectors, thanks to their outstanding machinability and wear resistance. Equipped with cutting-edge facilities and a commitment to quality control, Neith Metals is a go-to source for 20MnCr5 Round Bars in both the Egyptian and global markets.
20MnCr5 Round Bars are low alloy steel bars characterized by a chemical composition that generally includes 0.17–0.22% carbon (C), 1.1–1.4% manganese (Mn), and 0.8–1.1% chromium (Cr), along with small amounts of phosphorus (P) and sulfur (S). These bars are known for their remarkable toughness, wear resistance, and hardenability, particularly after undergoing carburizing. Their mechanical properties boast a tensile strength ranging from 800 to 1000 MPa, a yield strength of about 500 MPa, and impressive elongation and impact values. These features make 20MnCr5 an excellent choice for components that need to withstand strength, ductility, and wear resistance in challenging working environments.
