Abstract VAN QN (80) is a dual-phase steel with an equivalent yield strength of 80,000 psi and an exceptional combination of strength, formability, weldability, toughness and fatigue resistance. A dual-phase steel is one whose microstructure primarily consists of a mixture of ferrite and martensite or lower bainite. The high work-hardneing rate of VAN QN (80) permits the development of high strengths in formed parts in combination with excellent formability. Great weight savings have been achieved by its use for a number of automotive parts. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-373. Producer or source: Jones & Laughlin Steel Corporation.
