  4140 Steel Applications There are many SAE 4140 steel applications and when navigating your way to finding a new metal machining carrier/partner, it can be difficult to grasp just what’s out there. What types of metal rods , bars, and tubing are best suited for your facility, and what materials you should be using? SAE 4140 steel is widely used in many industrial fields for its strength and versatility, and therefore is important to know about it if you are considering using it in your facility. Here is an outline of its key characteristics and most common applications. What is SAE 4140 Steel? SAE 4140 steel is a low-alloy steel containing chromium and molybdenum as strengthening agents. These give great corrosion resistance and strength up to around 600°. These characteristics include high strength and good machinability that can easily be heat treated for increased hardness. 4140 Steel Composition Chromium, Cr 0.80 – 1.10 Manganese, Mn 0.75 – 1.0 Carbon, C 0.380 – 0.430 Silic...
