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;
- According to GB/T 25777 “Preparation methods of deposited metal
specimens for chemical analysis”, ADJUST the preparation of deposited
Solid wire electrodes/flux combinations for
submerged arc welding of stainless steels

5 Test methods
5.1 Chemical analysis of deposited metal
5.1.1 Specimen preparation
Deposited metal specimens for chemical analysis shall be prepared according
to the provisions of GB/T 25777, or may be prepared on the specimens for
mechanical properties or the pull-rods after breaking. In the arbitration test, it
shall be carried out in accordance with the provisions of GB/T 25777.
5.1.2 Analysis method
The chemical composition of deposited metal can be analyzed by any suitable
analytical method. In the arbitration test, it shall be carried out according to the
analytical method confirmed by the supplier and the buyer.
5.2 Mechanical properties of deposited metal
5.2.1 Base metal for test
The base material for the tensile test of deposited metal shall be a steel plate
equivalent to the chemical composition of the deposited metal. If other base
materials are used, it shall use the test welding consumables or other equivalent
welding consumables to weld the isolation layer on the groove face and the
surface of base plate. The thickness after processing shall not be less than 3
mm.
5.2.2 Flux drying specification
The flux before welding shall be dried at 250 °C~400 °C for 1 h~2 h or be dried
according to the specification recommended by the manufacturer.
