GB/T 17854-2018Solid wire electrodes /flux combinations for submerged arc welding of stainless steels (English PDF)

Foreword

This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This Standard replaces GB/T 17854-1999 "Stainless steel electrodes and fluxes for submerged arc welding". As compared with GB/T 17854-1999, the main changes are as follows.

- CHANGE the standard's name to "Solid wire electrodes/flux combinations for submerged arc welding of stainless steels";

- According to JIS Z 3324:2010, ADJUST the method of classification for stainless steel wire electrodes-flux combinations;

- DELETE the technical requirements for wire electrodes, executed in accordance with GB/T 29713 "Wire electrodes, strip electrodes, wires and rods for arc welding of stainless and heat resisting steels";

- DELETE the technical requirements for flux, and the relevant content is adjusted to GB/T 36037 "Fluxes for submerged arc welding and electroslag welding";

- According to JIS Z 3324:2010, ADD five classifications for deposited metal of F309L, F312, F16-8-2, F317L, and F347L, and CHANGE "F316CuL" to "F316LCu";

- According to the actual application needs of China, ADD four classifications for deposited metal of F309LMo, F385, F2209, and F2594;

- According to JIS Z 3324:2010, ADJUST the Ni content of the deposited metal classification F308L from "9.0%~11.0%" to "9.0%~12.0%", and ADJUST the Ni content of F316L and F316LCu from "11.0%~14.0%" to "11.0%~16.0%";

- According to JIS Z 3324:2010, ADJUST the percentage elongation after fracture of the deposited metal classification F308L from "25%" to "30%", and ADJUST the percentage elongation after fracture of F410 from "20%" to "15%", ADJUST the percentage elongation after fracture of F430 from "17%" to "15%";

- According to JIS Z 3324:2010, ADJUST the heat treatment specifications of deposited metal classifications F410 and F430;
