ASTM A992


ASTM A992 steel is a structural steel alloy often used in the USA for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m3. ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification . Tensile yield strength, 345 MPa ; tensile ultimate strength, 450 MPa ; strain to rupture 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 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 is required. ASTM A992 is written to cover all hot-rolled shapes."
