High-strength steel for heavy engineering SeverWeld (S460QL—S690QL)
SeverWeld (S460QL–S690QL) is a high-strength steel with high strength, good weldability and ductility.
- Turbine elements
- Hydro- and turbine generators
- 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
