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
