ASTM F290-94(2020)

Anotace textu normy ASTM F290-94(2020) :

This specification covers round wires made from UNS N02211, UNS N10001, or N03300 nickel alloy or molybdenum, with diameters within a specified range, for winding electron tube grid laterals. The wires are classified into five classes based on tensile properties. All wires should conform to the required values of tensile strength, yield strength, working range, and elongation properties. The surface of each bare wire should be bright and free from cracks, slivers, fissures, lubricants, or other detrimental defects, while all platings should be free from bubbles, flakes, blisters, porosity, and plating salts. Wires should be spooled in one continuous length and in such a manner that it can be unwound under reasonable tension without binding or becoming distorted.
