High-strength steel for heavy engineering SeverDom (S355MC−S700MC)

Main emphasis in the development of the production technology for high-strength steels SeverDom (S355MC-S700MC) is aimed at the strength properties of the product, as well as ductility, weldability of metal and toughness at negative temperatures, which is provided by low carbon content. It makes possible to produce products of complex shape and ensures their durability.
Application
  • Parts of hydro generators (power engineering)

Advantages

  • High strength and ductility due to specially developed steel alloying concept
  • Excellent weldability of steel due to reduced carbon content
  • Ability to withstand high loads, incl. impact loads, at low operating temperatures, due to lower content of harmful impurities in steel
