Type

This specification covers studs made from a corrosion and heat resistant, age hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286. The following specification designations and their properties are covered:

AS7482 130 ksi minimum ultimate tensile strength at room temperature 70 ksi stress-rupture strength at 1200 °F

AS7482-1 130 ksi minimum ultimate tensile strength at room temperature 78 ksi minimum ultimate shear strength at room temperature

AS7482-2 130 ksi minimum ultimate tensile strength at room temperature

Application

Primarily for aerospace propulsion system applications where a good combination of strength and resistance to corrosion are required. AS7482 studs are intended for use at elevated temperatures in corrosion resistant steel parts. AS7482-1 studs are intended for studs loaded in shear. AS7482-2 studs are intended for use where the coefficient of expansion of the stud is more compatible for use in aluminum or magnesium alloys.

Safety - Hazardous Materials

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
