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 currently the most available steel type for structural wide-flange beams.
The industry's technical institute describes the standard thus: "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.
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.
