This specification establishes requirements for steel forgings of any shape or form from which finished parts are to be made (See 8.2, 8.3.4, 8.5, and 8.6).
This specification covers steel cleanliness requirements in SI (metric) units for aircraft-quality ferromagnetic steels, other than hardenable corrosion-resistant steels, by magnetic particle inspection methods.
1. SCOPE: 1.1 Type: This specification covers high quality holts and screws made of a low-alloy, heat resistant steel. 1. 2 Application: Primarily for joining parts where high strength up to 900'F (480'C) is reqnired.
