40Cr is one of the most widely used alloy steels in precision manufacturing, valued for its balanced performance, cost efficiency, and excellent machinability. With reliable hardness, high tensile strength, and good wear resistance, it is widely applied to produce shafts, gears, bolts, connecting parts, and various structural components.
This material responds well to quenching and tempering treatments, allowing adjustable mechanical properties to meet different working requirements. It machines smoothly, supports grinding, and ensures stable dimensional accuracy after heat treatment, making it highly suitable for CNC turning, milling, and custom processing.
Compared with high‑grade alloy steels, 40Cr offers more competitive pricing without compromising basic performance for general industrial use. It works reliably in most mechanical equipment, automotive parts, and tooling applications.
We provide custom components made from genuine 40Cr steel, with strict material inspection and precise machining. Whether for OEM orders, small batches, or prototypes, we deliver durable, high‑quality parts that meet your specifications.
