PRODUCT DESCRIPTION
Grade S147 is usually produced by EAF / VD / LF followed by electroslag refining (ESR) if necessary for special purpose. 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.
