This 440C stainless steel round bar is ideal for high-strength, wear-resistant applications such as rolling element bearings, valve seats, high-quality knife blades, surgical instruments, molds and dies, and measuring instruments.

Yes, custom cut lengths are available from the warehouse, with options ranging from 12 inches up to 144 inches to suit your project needs.

After heat treatment, this 440C bar achieves very high strength and hardness, with an ultimate tensile strength of 100 ksi and a Rockwell hardness of 99, making it highly wear resistant.

Yes, this product is RoHS compliant and an MTR (Material Test Report) is available to verify its material properties and compliance.

The machinability rating is 40, indicating moderate machinability; this means it can be machined effectively but may require appropriate tooling and techniques due to its hardness.
