Die Annotation des Normtextes ASTM B350/B350M-11(2021) :

This specification covers vacuum-melted zirconium and zirconium alloy ingots for nuclear application. Materials covered shall be produced by multiple vacuum arc melting, or electron beam melting, or other melting processes conventionally used for reactive metals. Unless otherwise specified, ingots shall be conditioned by machining or grinding or both to remove surface and subsurface defects detrimental to subsequent fabrication. The ingot shall conform to the chemical composition requirements prescribed. The ingots shall be analyzed for the alloying and impurity elements prescribed. Ingots shall be inspected ultrasonically using the prescribed methods. The test shall be conducted in accordance with practice E 114.
