K-WHY

Cost effective saving process for on-line surface quenching and self-tempering

BENEFITS

Lower production cost in steel making/billet purchasing, high product quality with optimal final characteristics due to lower amount of alloying elements
High yield strength values ≥ 500 Mpa
Up to DB51 mm and grade 700/800/1000 and 1200 produced or treated in case of deformed bar production
Sufficient ductility with El ≥ 12%
Good weldability with carbon equivalent ≤ 0.40%
Approx. 18% and 8% cost saving if compared respectively with micro-alloyed or low-alloy steels
ROI: 6 to 12 months
