PRODUCT DESCRIPTION
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition.
Final heat treatment - quenched and tempered.
AVAILABLE SHAPES
Round bar / flat bar / hollow bar / strip / sheet
Bright - peeled + polishing, centerless grinding
Forged - ring, discs, shaft
