SAE AMS5620G

This specification covers two types of corrosion and moderate heat resistant steel in the form of bars, wire, forgings, and forging stock.

These products have been used typically for parts on which the amount of machining warrants use of free-machining grade of steel and requiring hardness within the range of 40 to 50 HRC with corrosion resistance and oxidation resistance up to 1000 \mDF (538 \mDC), but useful at the higher temperatures only when stresses are moderately low, 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.
