SAE 4140 Alloy Steel

As low-alloy steel, SAE 4140 is derived from iron, carbon, and other alloying elements. It is a medium-carbon steel characterized by strength, toughness, and wear resistance.SAE 4140 Has Both Chromium And Molybdenum As Its Primary Alloying Elements, Making It A Chromium-Molybdenum Steel With A Wide Range Of Mechanical Properties. Gears, shafts, spindles, and other machine parts can be made from it. In addition, SAE 4140 steel is widely used for downhole tools and wellhead components in the oil and gas industry. In addition to its high strength levels, SAE 4140 steel maintains good toughness and ductility after heat treatment. Sae 4140 Steel Has A Good Weldability And Machinability. Welded using the most common welding methods, it can also be machined using conventional methods. While hardened and tempered, it is difficult to machine due to its high hardenability. Among the industries where it is commonly used are construction, mining, oil and gas, and transportation. It is available in many sizes and shapes and conforms to ASTM A29/A29m standards.
