This specification covers a low-alloy steel in the form of bars, forgings, and forging stock.
These products have been used typically for parts requiring a steel capable of through-hardening to a minimum hardness of 50 HRC in section thicknesses up to 12 inches (305 mm) with relatively high levels of strength, fatigue resistance, ductility, and thermal stability in service from -100 degrees to +1000 degrees F (-73 degrees to +538 degrees C), 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.
