PRODUCT MELTING PROCESS
1.3812 is usually produced by AOD / EAF followed by electroslag refining (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied peeled bright condition.
Final heat treatment - solution + aged.
