Steel, bars, forgings, and tubing, 0.80Cr 1.8Ni 0.25Mo (0.38 0.43c). (SAE standard)
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. MAM 6415 is the metric version of this AMS. These products have been used typically for parts, 3.5 inches and under in nominal thickness at time of heat treatment, requiring a through-hardening steel capable of developing a minimum hardness of 40 HRC when properly hardened and tempered and also for parts of greater thickness but requiring proportionately lower 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. Alloy: 4340 UNS Number: G4340.
