High-strength steel for heavy engineering SeverWeld (S460QL—S690QL)

SeverWeld (S460QL–S690QL) is a high-strength steel with high strength, good weldability and ductility.
Application
  • Turbine elements
  • Hydro- and turbine generators

Advantages

  • High strength characteristics due to use of optimally selected
    micro-alloying scheme for steel and heat treatment of rolled product
  • High weldability due to limited carbon and carbon equivalent
  • Low content of harmful impurities in steel and optimally selected modes of
    hot rolling and heat treatment of rolled products provide cold resistance down to -70 °C
