Overview

EN 4245:2020 (CEN / ASD-STAN) defines material requirements for the aerospace heat-resisting alloy FE‑PM1708 supplied as vacuum arc remelted (VAR), as‑forged forging stock with maximum diameter D ≤ 300 mm. This European Standard is part of the aerospace metallic materials series and is intended to ensure consistent material quality, mechanical performance and producibility for high‑temperature aerospace components.

Key features covered by the standard:

• Material designation: Heat resisting alloy FE‑PM1708
• Method of melting: Vacuum arc remelted (VAR)
• Form and condition: As‑forged forging stock (delivery condition code U)
• Maximum diameter: D ≤ 300 mm
• Reference heat treatment: Quenched and tempered (see EN 4245:2020 for specific cycle parameters)

Key Topics

The standard provides prescriptive and normative requirements that are important for manufacturers, purchasers and design engineers:

• Chemical composition: Elements and limits are specified for FE‑PM1708 (C, Si, Mn, B, Co, Cr, Mo, Nb, Ni, V, N, etc.) to control alloy behaviour at elevated temperature.
• Mechanical properties: Minimum proof stress and tensile ranges are given. For example, proof stress Rp0.2 ≥ 880 MPa and tensile strength Rm between 1 000 and 1 140 MPa are specified in the standard. Elongation and reduction of area requirements vary with diameter.
• Testing & samples: Test sample preparation follows EN 2957; other dimensional and testing requirements reference EN 2860‑2.
• Non‑destructive inspection: Internal imperfection limits and ultrasonic testing classes are specified depending on diameter (different UT classes for D ≤150 mm, 150 mm < D <250 mm and D >250 mm).
• Delivery and heat treatment: Delivery condition and recommended reference quench and temper cycles are defined; purchasers and manufacturers are expected to agree any specific qualification programme.

Applications

FE‑PM1708 is intended for aerospace applications where heat resistance, high strength at elevated temperatures, and reliable forging behaviour are required. Typical uses include high‑temperature structural or engine components produced by forging from VAR stock, where traceable material specifications and qualification are essential.

Benefits of specifying EN 4245:2020 in procurement and design:

• Ensures consistent alloy chemistry and melting route (VAR) for improved homogeneity
• Defines mechanical property minima suitable for high‑temperature service
• Standardises testing, inspection and acceptance criteria for forging stock
