Title:Steel, Corrosion Resistant, Bars, Wire, Forgings, Rings, and Extrusions 15Cr - 4.5Ni - 0.30Cb (Nb) - 3.5Cu, Consumable Remelted, Precipitation Hardenable
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion-resistant steel in the form of bars, wire, forgings, flash welded rings, extrusions, and stock for forging, flash welded rings, or extruding.These products have been used typically for parts requiring corrosion resistance and high strength up to 600 掳F (316 掳C) with good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications.Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP1110 recommends practices to minimize such conditions.MIL-DTL-70446C (W/ AMENDMENT 1), DETAIL SPECIFICATION: MACHINE GUN, 5.56MM: M249 (27 MAR 2009) [SUPERSEDES MIL-DTL-0070446B & MIL-M-70446A]., This specification prescribes the detail requirements and identifies the verification procedures for the Machine Gun, 5.56MM: M249, hereafter referred to simply as the M249.
