BS 4S 28:1964+A3:2015

Overview

BS 4S 28:1964+A3:2015 specifies the requirements for 4 per cent nickel-chromium-molybdenum steel, which is known for its air hardening properties. This standard is crucial for applications in aircraft and space vehicle engineering, where material performance and reliability are paramount. The steel specified in this standard is characterised by a limiting ruling section of 63.5 mm and a tensile strength of 1545 MPa, making it suitable for high-stress environments.

Key Requirements

The standard outlines several key requirements that must be met for compliance. These include:

• Material Composition: The steel must contain 4 per cent nickel, chromium, and molybdenum, ensuring optimal mechanical properties.
• Tensile Strength: The material must achieve a minimum tensile strength of 1545 MPa.
• Heat Treatment: Specific heat treatment processes are prescribed to achieve the desired hardness and toughness.
• Testing Procedures: Rigorous testing methods must be employed to verify compliance with the standard's requirements.
