Structural steels

Structural steel are used in the engineering and automotive industries. Their properties are high yield strength, tensile strength, elongation, ductility and toughness. Depending on the alloying elements can be divided into low-alloyed and alloyed steels.

Depending on usage, we divided them to three groups:

  • steels for cementation
  • steels for quenching and tempering
  • nitriding steels
