適用范圍：This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. These products have been typically ised for critical carburized parts, such as bearings, operating under heavy loads and high speeds at moderate temperatures, and subject to very rigin inspection standards, but use is not limited to such applications.
