This hex bar is made from 347 stainless steel, known for high strength and excellent corrosion resistance in oxidizing environments. It offers an ultimate tensile strength of 93 ksi and a yield tensile strength of 39 ksi, making it suitable for high-temperature applications.

Yes, this hex bar is available for custom cutting with lengths up to 144 inches. Custom cuts are processed at warehouse 1, allowing you to order the exact size needed for your project.

Yes, this product complies with RoHS and REACH standards and comes with Material Test Reports (MTR) availability to ensure quality and compliance.

This hex bar is ideal for aerospace uses such as aircraft exhausts, collector rings, and expansion joints, as well as high-temperature chemical processing due to its high temperature capability and corrosion resistance.

The cold drawn process enhances the bar's strength and surface finish, providing better dimensional accuracy and mechanical properties compared to hot rolled bars.
