【国外标准】 Standard Specification for Magnesium-Alloy Forgings

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.1.1 This specification covers magnesium alloy forgings designated as shown in Table 1.(A) Limits are in weight percent maximum unless shown as a range or stated otherwise.(B) These alloy designations were established in accordance with Practice B951.(C) Includes listed elements for which no specific limit is shown.1.2 The values stated in inch-pound units are the standard. The SI values in parentheses are provided for information only.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
