Form:

This specification covers a premium aircraft-quality, corrosion-resistant steel in the form of bars, wire, forgings, mechanical tubing, and forging stock.

Application:

These products have been used typically for parts requiring a through-hardening, corrosion-resistant steel, operating under heavy loads at high speeds, requiring resistance to wear and softening at elevated temperatures, and subject to rigid inspection standards, but usage is not limited to such applications.
