Buy CK40 Carbon Steel Round Bar (UNS G10400) offering good strength and toughness. Ideal for shafts, gears, bolts, and engineering component
CK40 Round Bar is a medium-carbon steel bar manufactured to meet international standards like DIN CK40 / EN 1.1181, offering a balanced combination of strength, machinability, and wear resistance. With a carbon content typically around 0.37–0.44%, CK40 delivers higher mechanical strength and hardness than low-carbon steels, while still maintaining good formability and heat-treatable properties.
Available in various diameters and surface finishes such as black, turned, bright, and polished, CK40 round bars are ideal for precision machining and fabrication. Their moderate carbon content makes them suitable for parts that require high strength and durability, but with easier machining compared to higher carbon grades.
