Description / Abstract:

Type This procurement specification covers bolts and screws made from a low alloy, heat resistant steel of the type identified under the Unified Numbering System as UNS K14675, having UNJ profile threads. The following specification designations and their properties are covered

AS7459 195 ksi minimum ultimate tensile strength at room temperature

145 ksi minimum ultimate tensile strength at 900 °F

105 ksi stress rupture strength at 900 °F for 100 hours

100 ksi tension to 10 ksi tension fatigue at room temperature Protective treatment to be specified on part drawing

AS7459-1 AS7459 part plated per AMS2416, nickel-cadmium diffused plating

AS7459-2 195 ksi minimum ultimate tensile strength at room temperature 117 ksi minimum ultimate shear strength at room temperature Protective treatment to be specified on part drawing

AS7459-3 AS7459-2 part plated per AMS2416, nickel-cadmium diffused plating

Application

Primarily for aerospace propulsion system applications where high strength at temperatures up to approximately 900 °F is required and the part is protected against corrosion.
