Overview

SIST EN 3310:2012 is a European standard published by CEN that specifies the requirements for titanium alloy TI-P64001 (Ti-6Al-4V) forging stock. This standard addresses material used in the manufacture of annealed forgings, particularly for aerospace applications, with diameters up to and including 360 mm. As a key component in the aerospace series, SIST EN 3310:2012 ensures consistent quality, performance, and safety for titanium forgings used in critical aircraft structures and components.

Key Topics

• Material Specification: Covers the chemical and mechanical properties of the titanium alloy TI-P64001 (Ti-6Al-4V), focusing on material supplied in the not heat treated condition for subsequent annealing.
• Dimensional Range: Limits application to forging stock with diameters (De) of 360 mm or less.
• Production Requirements: Specifies requirements for form, melting method, acceptable microstructure, macrostructure, and external/internal defect criteria, referencing additional relevant standards.
• Mechanical Properties: Ensures minimum values for proof stress, tensile strength, elongation, and reduction of area - all critical for aero-engine and structural applications.
• Delivery Conditions: Details the supply state ("not heat treated"), identifying the need for subsequent heat treatment (annealing) before the final forging process.

Applications

SIST EN 3310:2012 is highly relevant in the following contexts:

• Aerospace Manufacturing: Ideal for producing critical structural and engine components where high strength-to-weight ratios and resistance to fatigue and corrosion are essential.
• Forging Stock Preparation: Guides the selection and preparation of titanium alloy bars and billets for further processing into annealed forgings. Common forged parts include landing gear, discs, and high-stress airframe links.
• Quality Assurance: Provides benchmarks for OEMs, suppliers, and certification bodies to assure conformity and traceability of titanium stock used in safety-critical applications.
• Material Procurement: Streamlines procurement by standardizing product specifications, dimensional tolerances, inspection, marking, and documentation requirements.

Compliance with SIST EN 3310:2012 supports manufacturers seeking to meet stringent airworthiness or aerospace quality management systems (e.g., EN 9100) and helps to facilitate international trade and interoperability within the aerospace sector.

Related Standards

SIST EN 3310:2012 references and is closely linked to several other key European standards in the aerospace series, including:

• EN 4800-005 – Titanium and titanium alloys – Technical specification for forging stock.
• EN 2032-2 – Codes for metallurgical condition in delivery condition.
• EN 2954-002 – Macrostructure requirements for titanium and titanium alloy wrought products.
• EN 3114-002 – Microstructure requirements for (α + β) titanium alloy wrought products.
• EN 4258 – Organization of metallic materials standardization in aerospace.
• EN 4500-4 – Rules for drafting and presentation of titanium and titanium alloy material standards.

These related standards work together to ensure a harmonized approach to material selection, testing, quality assurance, and regulatory compliance in the European aerospace industry.

SIST EN 3310:2012 is a critical reference for anyone involved in the specification, procurement, or production of titanium forging stock for high-performance aerospace applications.
