Overview

SIST EN 2483:2011 is a European standard developed by CEN that specifies the stringent requirements for Steel FE-PL2108 (36NiCrMo16) forgings used in aerospace applications. This standard targets steel forgings with a tensile strength (Rm) ranging from 1,100 MPa to 1,300 MPa and a maximum outer diameter (De) of 100 mm. The steel grade FE-PL2108 is a low-alloy, high-strength steel specifically tailored for the aerospace sector, ensuring optimal performance under demanding mechanical and environmental conditions.

This standard is part of the wider aerospace series standards that regulate metallic materials, ensuring consistency, reliability, and safety in aerospace components manufacturing. It encompasses chemical composition, mechanical properties, production methods, heat treatment, and stringent inspection requirements that aerospace parts must meet.
