What is the modulus of elasticity for A992 angle steel?

A992 angle steel has a modulus of elasticity (E) of 29,000 ksi (200 GPa)- identical to most structural steels (e.g., A36). Modulus of elasticity measures stiffness- the material's resistance to elastic deformation under stress. It is a critical design parameter for calculating deflection: for example, a 10 ft-long L4x4x0.5 A992 angle supporting a 500 lb load will deflect ~0.1 inches, calculated using E=29,000 ksi. Unlike yield strength, E is a material constant, not affected by work hardening or thickness, ensuring consistent deflection predictions across all A992 angles. Engineers rely on this value to ensure angles meet deflection limits (e.g., preventing cracking in attached drywall or concrete), a key requirement for occupant comfort and structural safety.
