 specification A992/A992M. Tensile yield strength, 345 MPa (50 ksi); tensile ultimate strength, 450 MPa (65 ksi); strain to rupture (sometimes called elongation) in a 200-mm-long test specimen, 18 %; strain to rupture in a 50-mm-long test specimen, 21 %.

ASTM A992 is the industry standard for all structural wide-flange beams.

From the American Institute of Steel Construction: "ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred material specification for wide-flange shapes, having replaced ASTM A36 and A572 grade 50. There are a couple of noteworthy enhancements with ASTM A992. Material ductility is well defined since a maximum yield-to-tensile strength ratio of 0.85 is specified. Additionally, weldability is improved since a maximum carbon equivalent value of 0.45 (0.47 for Group 4 and 5 shapes) is required. ASTM A992 is written to cover all hot-rolled shapes."
