What is ASTM A992 equivalent to?
ASTM A992/A992M equivalent to EN 10025 S355J2,Australian AS/NZS 3678: Grade 350 L20; Canadian G40.,In China, the corresponding national standard material is GB/T 1591-2018 High Strength Low Alloy Structural Steel. This standard was released in 2018, replacing the original GB/T 1591-2008 standard. Compared with ASTM A992, the GB/T 1591-2018 standard has more steel strength grades, including Q345B, Q345C, Q345D, Q345E, Q390B, Q390C, Q390D, Q420B, Q420C, Q420D, Q460C, Q460D, Q460E, etc.
ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m3 (0.2836 lb/in3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM 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 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. 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.
