SAE AMS 6427L

Steel Bars, Forgings, and Tubing 0.88Cr 1.8Ni 0.42Mo 0.08V (0.25-0.33C) (4330 Mod)

SAE International / 21-Dec-2012

This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.These products have been used typically for parts requiring a combination of high tensile strength and good ductility with relatively-high impact strength and hardness, but usage is not limited to such applications. Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment. SAE ARP 1110 recommends practices to minimize such conditions.
