SAE 1018 carbon steel is a widely used low-carbon, free-machining grade with 0.12 to 2% carbon content. As the carbon content increases, steel hardness and strength improve, but ductility decreases. SAE 1018 is favored for its versatility in forming, machining, welding, and fabrication. Although its mechanical properties aren’t exceptional, i
