Stainless Steel Rectangle Bar 15-5 is a solid rectangular bar made from 15-5 precipitation hardening stainless steel alloy containing chromium, nickel, copper, and other elements that provide high strength, hardness, and corrosion resistance after aging heat treatment. Its rectangular cross-section, stainless steel composition, and excellent mechanical properties make it suitable for applications requiring durability and resilience in harsh environments, such as in the manufacturing of tools, shafts, structural components, and other applications where good corrosion resistance and mechanical strength are necessary.
