S460 Steel is a high-strength structural steel commonly used in construction and engineering applications. It is part of the European standard EN 10025, which specifies the requirements for hot-rolled structural steel. The "S" in S460 stands for "structural," while the "460" indicates a minimum yield strength of 460 megapascals (MPa). This steel grade is known for its excellent weldability and toughness, making it suitable for various structures, including bridges, buildings, and heavy machinery. Its high strength allows for lighter structures, which can lead to cost savings in materials and construction.
