This specification covers UNS M11311, M11610, M11800, or M16600 magnesium alloy forgings. The conformance of each material to the required chemical composition can be determined using any suitable method of chemical analysis. Samples for chemical analysis should be taken when the ingots are poured or from the finished or semi-finished products by drilling, sawing, milling, turning, or clipping. The variations in testing speed do not seriously affect the obtained tensile property values. However, care must be exercised so that the testing speed does not exceed the ability of the equipment to function satisfactorily. Unless specified, forgings should be chrome pickled before shipment.
