BS EN 2476:2019

Overview

BS EN 2476:2019 is a critical standard within the aerospace sector, specifically addressing the requirements for steel 30CrNiMo8 (1.6580) used in the manufacture of forgings. This standard is applicable to components that require high strength and toughness, with a tensile strength range of 1 100 MPa to 1 300 MPa. The standard is particularly relevant for forgings with a diameter of up to 100 mm, ensuring that materials meet stringent performance criteria essential for aircraft and space vehicle engineering.

Key Requirements

The standard outlines specific requirements for the chemical composition, mechanical properties, and testing methods for steel 30CrNiMo8. Key aspects include:

• Chemical Composition: The steel must conform to specified limits for elements such as carbon, chromium, nickel, and molybdenum to ensure optimal performance.
• Mechanical Properties: The material must exhibit a tensile strength (Rm) between 1 100 MPa and 1 300 MPa, ensuring it can withstand the demanding conditions encountered in aerospace applications.
• Forging Process: The standard specifies acceptable forging practices to maintain the integrity and performance of the material.
• Testing Procedures: Rigorous testing methods are defined to verify compliance with the mechanical and chemical specifications.

Implementation Benefits
