BS 2HR 51:2010

Overview

BS 2HR 51:2010 is a critical standard in the field of aircraft and space vehicle engineering, specifically addressing the specifications for high expansion heat-resisting steel billets, bars, forgings, and parts. This standard is essential for manufacturers and engineers involved in the production of components that must withstand extreme temperatures and mechanical stresses. The alloy composition specified includes Nickel (Ni 25.5), Chromium (Cr 15), Titanium (Ti 2), Manganese (Mn 1.5), Molybdenum (Mo 1.25), Silicon (Si 0.7), and Vanadium (V 0.3), with the material being solution treated at 980 °C.

Key Requirements

The standard outlines several key requirements for the material properties and testing methods necessary to ensure compliance. These include:

• Material Composition: Adherence to the specified alloying elements to ensure optimal performance under high-temperature conditions.
• Heat Treatment: The solution treatment process at 980 °C must be strictly followed to achieve the desired microstructure and mechanical properties.
• Mechanical Properties: The standard specifies minimum requirements for tensile strength, yield strength, and elongation, ensuring that the material can perform reliably in demanding applications.
• Testing Methods: Detailed procedures for mechanical testing, including tensile tests and hardness tests, are provided to validate compliance with the standard.
