Aerospace series - Fasteners, externally threaded, in heat resisting nickel base alloy NI-PH2601 (Inconel 718) - Classification 1 275 MPa/650 °C - Manufacturing method optional - Technical specification

This standard specifies the technical and quality assurance requirements for externally threaded fasteners in material NI-PH2601 (Inconel 718) of tensile strength class 1 275 MPa at room temperature, maximum test temperature of material 650 °C.
The externally threaded fasteners specified herein may be manufactured by machining from bar or by forging at the manufacturer's option, if forged there is no requirement for control of grainflow.
Primarily for Aerospace applications it is applicable to such externally threaded fasteners when referenced on the product standard or drawing.

Luft- und Raumfahrt - Verbindungselemente mit Außengewinde aus hochwarmfester Nickelbasislegierung NI-PH2601 (Inconel 718) - Klasse : 1 275 MPa/650 °C - Herstellverfahren nach Wahl - Technische Lieferbedingungen

Diese Norm legt die technischen Anforderungen und die Anforderungen an die Qualitätssicherung für
Verbindungselemente mit Außengewinde aus dem Werkstoff NI-PH2601 (Inconel 718), Zugfestigkeitsklasse
1 275 MPa bei Raumtemperatur, maximale Prüftemperatur des Werkstoffes 650 °C, fest.
Die in dieser Norm festgelegten Verbindungselemente mit Außengewinde können nach Wahl des Herstellers
durch Zerspanen von Stangen oder durch Schmieden hergestellt werden, bei geschmiedeten Verbindungselementen
ist keine Überprüfung des Faserverlaufs erforderlich.
Diese Norm gilt in erster Linie für Anwendungszwecke im Bereich Luft- und Raumfahrt und ist für diejenigen
Verbindungselemente mit Außengewinde anzuwenden, bei denen in der zugehörigen Produktnorm oder
Zeichnung auf sie verwiesen wird.
