The 440C stainless steel square bar offers high strength with an ultimate tensile strength of 100 ksi and a yield tensile strength of 65 ksi. It also has excellent hardness, reaching up to 99 on the Rockwell scale, making it suitable for wear-resistant applications.

This product is available in a maximum length of 36 inches and is offered in a ground production method. However, the custom cut warehouse availability is zero, indicating no custom cutting service from the warehouse.

Due to its high hardness and wear resistance after heat treatment, the 440C bar is ideal for rolling element bearings, valve seats, high-quality knife blades, surgical instruments, chisels, gage blocks, molds and dies, and valve components.

Yes, this stainless steel square bar complies with RoHS (Yes 6C), but it is not REACH compliant.

Yes, an MTR report is available for this product, providing detailed material certification.
