Scope
NB/T 20008.14-2013 is the English-translated version of 压水堆核电厂用其他材料 第14部分：镍-铬-铁合金弹簧丝.
Part 14 of the NB/T 20008 series, NB/T 20008.14-2013 is a recommended Chinese energy industry standard for the nickel-chromium-iron alloy wire from which springs are made in pressurized water reactor nuclear power plants.
It covers the manufacture of that wire and sets requirements for chemical composition, mechanical and processing properties, microstructure, surface quality, and dimensions and shape.
The grade sits under the international classification for steel wire, and its chemical composition is determined by the GB/T 223 family of analytical methods that the text cites at length.
The document supersedes EJ/T 481-1999, carrying the earlier nuclear industry specification into the energy industry series. Issued on 8 June 2013, it has applied since 1 October 2013.
