Meanwhile, these Hastelloy B3 Hollow Bars are also being offered in customized sizes and shapes to our customers. Austenitic steels such as Hastelloy B3 Hexagonal Bars are non – magnetic stainless steels that contain high levels of chromium and nickel and low levels of carbon. Known for their formability and resistance to corrosion, austenitic steels such as Hastelloy B3 Triangular Bars are the most widely used grade of stainless steel.

In addition to being non – magnetic, austenitic stainless steels such as Hastelloy B3 Bars are not heat treatable. Hastelloy B3 Rods can be cold worked to improve hardness, strength, and stress resistance. In addition, Alloy B3 Rods provides excellent elevated temperature tensile, creep and stress – rupture strengths, as well as outstanding formability and weldability.
