QST
In line quenching & self-tempering system for beams
BENEFITS
  • Broadens market share to include fine grain steels
  • Improves mechanical properties with reduced quantities of alloying such as V and Nb
  • International standards such as ASTM A913, EN 10025, JIS G 3106, etc. are respected
  • Increased weldability compared to beams with the same tensile properties due to an inferior quantity of C and other alloys
  • Fine-grain steel allows a lower steel weight in building constructions
  • ROI: < 3 years considering a production of 60,000 tpy of QST beams
