The standard ASTM B737 specifies the requirements for hafnium and hafnium alloys in the form of bars and wires. This specification includes provisions for chemical composition, mechanical properties, dimensional tolerances, and surface finish. The products are manufactured through vacuum melting in electron beam or consumable arc furnaces, followed by hot or cold working, and are delivered in the recrystallized annealed condition unless otherwise specified.
ASTM B737 is applied worldwide to ensure the quality and reliability of hafnium products in applications exposed to high temperatures, corrosive environments, and mechanical stress. The standard provides a solid foundation for consistent product quality in demanding industrial environments.
Hafnium produced according to ASTM B737 is renowned for its high melting point, excellent corrosion resistance, and good mechanical properties at elevated temperatures. The material maintains its strength and ductility under thermal stress and offers stability in aggressive chemical environments. In nuclear applications, hafnium is valued for its ability to absorb neutrons, while in other industries, it is utilized for its durability and resistance to oxidation.
Materials conforming to ASTM B737 are extensively used in sectors where high performance is required under extreme conditions. Typical applications include:
Components for nuclear reactors, such as control rods, due to hafnium’s excellent neutron absorption properties.
Electronic parts and semiconductor equipment, where hafnium is used in thin films and as an alloying element.
Aerospace applications requiring lightweight and high strength, such as in jet engines and rocket components.
The combination of thermal stability, mechanical strength, and corrosion resistance makes hafnium according to ASTM B737 a reliable choice for critical industrial applications.
