Structural Steel Technology

Module aims

  • To understand structural steel physical metallurgy
  • To apply this knowledge to the manufacture of steels, including welding
  • To understand the factors leading to corrosion and brittle fracture of steel

Learning outcomes

On successfully completing this course unit, students will have:

  • Knowledge of the basics of steel metallurgy
  • An understanding of how to change the mechanical and corrosion properties of structural steel, including a basic understanding of how to assess steel for flaws
  • Knowledge of the manufacturing processes for steels and their effect on steel properties, including the effect of welding
  • Knowledge of corrosion processes and corrosion prevention techniques for steel structures

Module syllabus

Underlying chemistry of steel alloys; steel manufacturing methods; microstructure development and the effect of heat treatments; properties of steels, including a qualitative treatment of brittle fracture; quality control principles; methods of fabrication; tolerances and workmanship; connection philosophy; welding technology; corrosion; non-destructive testing; use of relevant codes.
