Overview
EN 2279:2018 is a European (CEN) aerospace material standard that defines the requirements for Steel FE‑PM37 used in forged aerospace components. The standard targets high‑strength forgings with a tensile strength 900 MPa ≤ Rm ≤ 1 100 MPa and maximum forging diameter De ≤ 150 mm. It is part of the EN aerospace series and references general rules for metallic material standards and forging specifications.
Key topics and technical requirements
- Material designation: Steel FE‑PM37.
- Mechanical range: Tensile strength Rm between 900 and 1 100 MPa (as the material class requirement).
- Form and size: Intended for forgings with De ≤ 150 mm.
- Chemical composition (typical limits given in the standard):
- C: 0.08 – 0.13%
- Si: max 0.35% (min not specified)
- Mn: 0.50 – 0.90%
- P: max 0.030% (min not specified)
- S: max 0.025% (min not specified)
- Cr: 11.0 – 12.5%
- Mo: 1.50 – 2.00%
- Ni: 2.00 – 3.00%
- V: 0.25 – 0.40%
- N: 0.020 – 0.040%
- Melting method: Air melted.
- Heat treatment / delivery conditions: Options include softened and hardened & tempered conditions. The standard gives a reference heat treatment: harden at 1 050 ± 10 °C followed by tempering at 650 ± 5 °C.
- Testing and inspection: The standard refers to sampling, test-piece direction (L or LT), and common mechanical test types (proof stress, hardness in HB, elongation), with specific test methods and acceptance criteria to be applied per EN 2157‑1 and purchaser/manufacturer agreement.
- Conformance: Product qualification and inspection programs are to be agreed between manufacturer and purchaser.
Applications and users
EN 2279:2018 is intended for:
- Aerospace manufacturers specifying high‑strength forged parts (shafts, fittings, landing gear subcomponents where size and strength limits apply).
- Material engineers and metallurgists selecting steel grades for forgings requiring controlled chemistry and heat treatment.
- Procurement and quality assurance teams who need a standardized technical specification for supply contracts and inspections.
- Test laboratories performing mechanical and metallurgical verification against EN requirements.
