This specification covers a corrosion-resistant steel in the form of sheet and strip. These products have been used typically in aircraft structural components requiring forming and bending during fabrication and where corrosion resistance up to 800 degrees F (427 degrees C) is required but usage is not limited to such applications. Mechanical properties specified herein are obtained by cold working (strain hardening) and not by heat treatment. Therefore, the cold-worked product should not be heated to a temperature which adversely affects the mechanical properties or corrosion resistance before, during, or after fabrication.
