General Engineering and Structural Steels is a steel group used in the production of various construction or machine components. Most of these steels are alloyed with carbon and manganese only or by micro alloying. In this way, many General Engineering and Construction Steel grades approach to Quenched and Tempered, Case Hardening or Nitriding qualities. Due to their versatility, this group is called the General Engineering and Structural Steel group.
General Engineering and Structural Steels are regulated by standards in most countries. In European Union, most of the Structural Steels take S as prefixes and Engineering Steels as E, followed by yield strength; for example S235, S355, E470, E520 etc.
These Standards also regulates shapes, sizes, chemical compositions, mechanical properties, storage applications, etc.
