37、Q-A-250. 6.NOTES: 6.1Intended Use: Alloy 6061 plate and sheet are intended for use where good strength and workability are required. For airframe applications alloy 6061 is considered an inherently corrosion-resistant alloy. Welding of alloy 6061 may require special precautions to avoid unsatisfacto
38、ry properties in weld and heat- affected zones of welded joints. Welding of alloy 6061 is not acceptable to NAVFAC or NAVSEA as a method of joining. 6.2Mechanical Properties After Heat Treatment: Mechanical properties of producer-supplied material are certified for the temper of material supplied. T
39、he producers “capability“ demonstration is not evidence that user-treated material conforms to property requirements of a given temper. Frequently, user-heat-treated material may develop a lower level of properties, especially if any cold, warm, or hot work is introduced prior to heat treatment. The
40、 user should be held responsible for demonstrating the acceptability of his processing for the end use. 6.3Ordering Data: Purchasers should select the preferred options permitted herein and include the following information in procurement documents: Title, number, and date of this specification shee
