ASTM a992 steel is recognized as the most suitable steel for wide flange beam in the world. It contains a variety of alloy elements, such as vanadium, niobium, copper, nickel, chromium and molybdenum, which greatly improve its strength and other properties. For example, the mechanical properties are much better than the tensile strength 65ksi and yield strength 65ksi of a572-50 and A36. Therefore, a992 wide flange beam (H beam) generally replaces a572-50.
