Beschreibung
Zusammenfassung:	The invention concerns a submerged burner for a furnace for melting glass or rock, said burner consisting at least partially, and preferably totally, of an alloy of the following composition, expressed as weight percentages of the alloy: Cr 11 to 22% Ni 5 to 20% Mo less than 6%, preferably less than 5% Mn less than 3%, preferably less than 2% Si less than 2%, preferably less than 1% N less than 0.2 %, preferably less than 0.1% P less than 0.1 %, preferably less than 0.05% S less than 0.05%, the remainder being made up of iron, carbon and inevitable impurities, said alloy being characterised in that the weight ratio Cr/C in said alloy is greater than 500, and preferably greater than 530.
