With the increasing popularity of the austenitic, super austenitic and duplex stainless steels foundries are facing an increasing need to ensure the economic supply of quality melt base and also the control their foundry returns - the AOD refining route meets these needs.
Many end users and specifiers including BP, Statoil, Norsok, the NACE technical committee and CTi recognise the value and importance of using refined melting stock and the use of refined material is mandatory for some contracts.
