Overview

SIST EN 3310:2012 is a European Standard developed by CEN, specifying the technical requirements for aerospace-grade titanium alloy TI-P64001 (Ti-6Al-4V). This standard covers forging stock material that is not heat treated and intended for annealed forgings with a diameter (De) up to 360 mm. As part of the aerospace series of metallic material standards, EN 3310 defines the chemical composition, mechanical properties, production methods, and inspection criteria to ensure the material's suitability for critical aerospace applications.

This titanium alloy is widely used in aerospace due to its excellent strength-to-weight ratio, corrosion resistance, and good mechanical performance at elevated temperatures. The standard provides a framework for manufacturers and purchasers, ensuring uniformity and reliability in titanium forgings for aerospace components.

Key Topics

• Material Designation: Titanium alloy TI-P64001 (Ti-6Al-4V), a popular α+β titanium alloy.
• Chemical Composition: Specified limits for aluminum (min 5.50%, max 6.75%), vanadium (3.50%–4.50%), and strict control of impurities such as oxygen, hydrogen, iron, and carbon.
• Form and Dimensions: Forging stock with an external diameter not exceeding 360 mm.
• Production Method: Melting as per EN 4800-005, non-heat-treated delivery condition (coded Ua).
• Mechanical Properties:
  • Proof stress (Rp0.2) ≥ 830 MPa
  • Tensile strength (Rm) between 900 MPa and 1160 MPa
  • Minimum elongation (A) of 10%
  • Reduction of area (Z) ≥ 25%
• Microstructure and Macrostructure: Acceptable microstructural classifications based on diameter ranges, ensuring consistent material quality and performance.
• Annealing Heat Treatment: Optional reference heat treatment between 690 °C and 840 °C with controlled cooling to achieve desired microstructure before forging.
• Testing and Verification: Includes dimensional, macro/microstructure inspections, chemical composition checks, and batch uniformity verification as per related aerospace test methods.
• Marking and Documentation: Clear guidelines for product marking, traceability, and compliance documentation to support aerospace quality assurance.

Applications

SIST EN 3310:2012 titanium alloy TI-P64001 forging stock is designed explicitly for aerospace uses where high performance and reliability are critical. Typical applications include:

• Structural airframe components
• Landing gear parts
• Engine components
• Fasteners and connectors requiring high strength, toughness, and corrosion resistance
• Critical parts subjected to cyclic loading and fatigue stress

The standard ensures that material delivered for these aerospace applications meets stringent requirements for mechanical strength and physical integrity without additional heat treatments, facilitating manufacturers’ ability to produce annealed forgings aligned with aerospace safety and performance demands.
