Description / Abstract:
Form:
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, and forging stock.
Application:
Primarily for parts requiring a combination of relatively-high strength, fatigue resistance, toughness, ductility, and thermal stability for operation between -100° and +1000°F (-73° and +538°C) and where such parts may require welding during fabrication.
