適用范圍：This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, flash welded rings, and stock for forging or flash welded rings. These products have been used typically for heat treated parts, which may be welded during fabrication, requiring through-hardening to high strength levels, and which may be used at operational stress levels approaching the yield strength, but usage is not limited to such applications.
