Steel Bars, Forgings, and Tubing, 0.88Cr - 1.8Ni - 0.42Mo - 0.08V (0.25 - 0.33C) (4330 Mod) AMS6427E

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. ARP1110 recommends practices to minimize such conditions.
