Overview
EN 3150:1995 (Aerospace series) defines the characteristics of headless shoulder pins manufactured from the heat‑resisting nickel‑base alloy NI‑P100HT (Inconel 718) for aerospace use. Published by CEN, the standard establishes the required attributes for these specialty pins and references EN 3368 for installation‑hole requirements. EN 3150 is used where high temperature strength and corrosion resistance of Inconel 718 are required in precision locating and load‑bearing pin applications.
Key Topics
The standard covers the essential characteristics and quality expectations for headless shoulder pins in NI‑P100HT, typically including:
- Material specification: use of the heat‑resisting nickel‑base alloy NI‑P100HT (Inconel 718).
- Pin geometry and shoulder form: nominal configurations and design intent for headless shoulder pins (locating/shouldered pins).
- Dimensional features and tolerances: required dimensions and tolerances to ensure fit and repeatability in aerospace assemblies.
- Installation and hole interface: installation hole guidance and compatibility - see EN 3368 for hole preparation and installation details.
- Surface finish and treatment: expectations for surface condition and any permissible post‑processing (e.g., passivation or coatings) relevant to performance at elevated temperatures.
- Quality, testing and acceptance: inspection, material verification and testing methods appropriate for aerospace fasteners manufactured from high‑temperature alloys.
- Marking and traceability: identification, batch traceability and documentation needed for aerospace supply chains.
(Note: EN 3150 defines these topics at a standard level; do not use this summary as a substitute for the full standard text.)
Applications
EN 3150 applies where high‑temperature resistance, strength and corrosion resistance are critical, for example:
- Engine components, hot‑section assemblies and support hardware
- Structural locating pins in high‑temperature zones
- Aerospace assemblies requiring precise shoulder locators with high fatigue and creep resistance
Users include design engineers, fastener manufacturers, procurement teams, quality/inspection personnel, and maintenance/repair organizations (MRO) working within the aerospace supply chain.
Related Standards
- EN 3368 - installation holes for these pins (referenced by EN 3150)
- Other aerospace fastener standards and specification documents for material certification, heat treatment and testing (consult full standards list for cross‑references)
Using EN 3150 helps ensure consistent performance and interchangeability of headless shoulder pins in NI‑P100HT (Inconel 718) applications across aerospace programs and suppliers.
