本规范已于2007年10月由SAE航空航天材料部宣布“取消”，并已被AWS A5取代。31类FB3-D、FB3-I或FB3-J。符合最新版AMS AWS A5的要求。当参考已取消的AMS 3417B时，应满足31（钎焊和钎焊用助焊剂规范）。通过这一行动，本文件仍将列在航空航天材料规范索引的数字部分，并指出其已被AWS A5取代。 31类FB3-D、FB3-I或FB3-J。本规范涵盖膏体或粉末形式的高温钎焊助焊剂。该焊剂通常与铜合金和金镍填充金属一起使用，用于镍合金、含奥氏体钢的黑色金属以及碳化钨和铬的焊炬钎焊，温度范围为1700至2200华氏度（927至1204摄氏度）。焊剂也可用于涉及高温钎焊长加热周期的关键加热应用，或用于快速感应加热应用等密集局部加热周期，但使用不限于此类应用。

This specification has been declared “CANCELLED” by the Aerospace Materials Division, SAE, as of October, 2007 and has been superseded by AWS A5.31 Types FB3-D, FB3-I, or FB3-J. The requirements of the latest issue of AMS AWS A5.31 (Specification for Fluxes for Brazing and Braze Welding) shall be fulfilled whenever reference is made to the cancelled AMS 3417B. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it has been superseded by AWS A5.31 Types FB3-D, FB3-I, or FB3-J.This specification covers a high temperature brazing flux in the form of paste or powder.This flux has been used typically with copper alloy and gold-nickel filler metals for torch brazing of nickel alloys, ferrous metals including austenitic steels, and tungsten and chromium carbides, at temperatures in the range 1700 to 2200 degrees F (927 to 1204 degrees C). Flux may also be used for critical heating applications involving long heating cycles for high temperature brazing, or for intense, localized heating cycles such as fast induction heating applications, but usage is not limited to such applications.
