BS 3HR 202:2009

Overview

BS 3HR 202:2009 provides a comprehensive specification for nickel-chromium-cobalt-titanium-aluminium heat-resisting alloy sheet and strip. This standard is essential for professionals involved in aircraft and space vehicle engineering, ensuring that materials used in these critical applications meet stringent performance and safety requirements.

Key Requirements

The standard outlines the chemical composition and mechanical properties of the alloy, which includes:

• Nickel Base: The primary component, providing excellent corrosion resistance and high-temperature strength.
• Chromium (Cr 19.5%): Enhances oxidation resistance and contributes to the alloy's overall strength.
• Cobalt (Co 18.0%): Improves wear resistance and maintains mechanical properties at elevated temperatures.
• Titanium (Ti 2.5%): Aids in stabilising the alloy structure and enhancing strength.
• Aluminium (Al 1.5%): Contributes to oxidation resistance and improves the alloy's overall performance.

The standard also specifies the manufacturing processes, testing methods, and quality assurance protocols necessary to ensure that the alloy meets the required specifications.
