Al Summan Metals, a top manufacturer and supplier headquartered in Dubai, UAE, focuses on producing and delivering high-quality alloy steel products, such as the widely sought-after 20MnCr5 Round Bars. Supported by state-of-the-art production facilities and a strong dedication to global quality standards, Al Summan Metals ensures that their materials deliver outstanding performance, longevity, and accuracy. They serve a broad spectrum of industries, ranging from automotive and engineering to machinery and power generation. Known for their reliability and technical know-how, Al Summan Metals consistently provides 20MnCr5 Round Bars that meet the rigorous demands of today’s industrial applications, both across UAE and internationally.
20MnCr5 Round Bars are low-alloy case-hardening steels consisting of approximately 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 composition strikes an optimal balance between core toughness and surface hardness after the carburizing process. The material delivers remarkable mechanical properties, featuring a tensile strength ranging from 550 to 850 MPa, as well as good ductility and high wear resistance. 20MnCr5 maintains its structural integrity even when placed under stress, making it an excellent choice for components that need both a hard surface and a resilient core to enhance fatigue performance.
