This specification covers a corrosion-resistant steel in the form of two types of aircraft tubing.This tubing has been used typically in the fabrication of aircraft structural parts requiring good corrosion resistance, but usage is not limited to such applications. This tubing is not suitable for use in applications requiring flaring or shaper bends. Welding or other exposure over 800 mDF (427 mDC) during fabrication may impair corrosion resistance.
