New Project Request
Steel, Bars, Forgings, and Tubing, 0.80cr 1.8ni 0.25mo (0.38 0.43)
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock procured in SI (Metric) units.<p>AMS 6415 is the inch/pound version of this MAM.<p>These products have been used typically for parts, 90 millimeters 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.<p>Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking after heat treatment; ARP 1110 recommends practices to minimize such conditions.
