Type

This standard covers bolts and screws made from a corrosion and heat resistant, age hardenable nickel base alloy of the type identified under the Unified Numbering System as UNS N07718.

Classification

AS4877 (where "-1" is not included):

a. Tensile strength at room temperature: 185 ksi minimum.

b. Maximum test temperature of parts: 1200 °F.

c. Tensile strength at 1200 °F: 145 ksi minimum.

d. Stress rupture: 100 ksi stress rupture strength at 1200 °F.

e. Fatigue strength at room temperature: 105 ksi minimum.

AS4877-1:

a. Tensile strength at room temperature: 185 ksi minimum.

b. Ultimate double shear strength at room temperature: 111 ksi minimum.

Application

Primarily for use in aerospace propulsion systems as follows:

a. For use up to approximately 1200 °F where elevated temperature, tensile strength, stress-rupture strength, and resistance to relaxation are required.

b. For use up to approximately 800 °F where fatigue resistance and tensile strength are required.

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.

Usage of Existing Manufactured Stock

Unless otherwise specified, part inventory manufactured to previous revisions of this specification may be procured and used until stock is depleted.
