ASTM B737-10(2021)

Annotation of standard text ASTM B737-10(2021) :

This specification covers hot-, cold-, or both hot- and cold-rolled hafnium rods and wires in either one of two grades. All grades should be in the recrystallization annealed condition unless specified otherwise. The materials should be made from ingots produced by vacuum melting in an electron beam or consumable arc furnaces, or both, of a type conventionally used for reactive metals. Samples for chemical composition tests should be taken from the top, middle, and bottom of the ingots. The requirements for mechanical properties do not apply to wires. Corrosion tests shall be done in water. All rods should be furnished in mechanically descaled and pickled, centerless ground and pickled, or centerless ground, pickled, and oxidized surface finish, while wires should be furnished in either conditioned and pickled or conditioned, pickled, and oxidized surface finish.
