These materials are essential in various engineering, industrial, and structural applications. Known for its remarkable toughness, fatigue strength, and wear resistance, 4140 is a chromium-molybdenum alloy steel. Daksh prides itself on delivering precision-engineered 4140 plates that adhere to both national and international standards, ensuring they perform reliably even under high-stress and impact conditions. With strong manufacturing capabilities and a dedication to quality and customer satisfaction, Daksh serves a wide range of sectors, including construction, oil & gas, automotive, mining, and general engineering, providing dependable alloy steel solutions.
4140 steel is a low-alloy steel that includes chromium (0.80–1.10%), molybdenum (0.15–0.25%), carbon (0.38–0.43%), and manganese (0.75–1.00%). This unique blend offers a great balance of strength, hardness, and toughness. Typically, it boasts a tensile strength ranging from 655 to 1080 MPa and a yield strength between 415 and 655 MPa, along with excellent fatigue and impact resistance. For improved mechanical properties, 4140 can be heat-treated through quenching and tempering. It also provides good machinability and fair weldability, making it an ideal choice for demanding applications where strength and wear resistance are crucial.
