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
