Constructional

Print

These steel grades include unalloyed high grade steels as well as quality steels. Usually these steel grades are classified as follows:

  • Unalloyed steels
  • Alloyed steels (microalloyed and low alloyed)

Constructional steels are used in very different applications. Depending on the final use the following properties are required:

  • High yield point
  • Plastic deformation
  • Machinability
  • Low Temperature Ductility
  • Thermal conduction
  • Expansion
  • Weldability

Finishing

  • hot rolled
  • forged
  • cold finished



Heat treatment

All standard heat treatment conditions are available.
