Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 17853-1999 "stainless steel flux cored wire". And GB/T 17853-1999 "stainless steel flux cored wire"

The main content changes are as follows.

--- According to ISO 17633.2010 and China's actual application needs, increased 309H and other 12 gas-protected non-metal powder cored welding

Classification of silk chemical components, 316H and other 10 self-protecting non-metallic powder type flux cored wire chemical composition classification and 308L and other 13 gas

Body protection metal powder type flux cored wire chemical composition classification;

--- The requirements for model division, chemical composition and mechanical properties were adjusted according to ISO 17633.2010;

--- Removed the requirement for longitudinal bending test of welded joints;

--- According to ISO 17633.2010, the T-joint fillet weld test requirements have been added.

This standard uses the redrafting method to modify the use of ISO 17633.2010 "welding material gas protection and self-protection arc welding stainless steel

Flux Cored Wire and Filled Wire Classification (English version).

Compared with ISO 17633.2010, this standard has more adjustments in structure. Appendix A lists this standard and ISO 17633.2010.

Checklist of changes in the number of chapters;

There are technical differences between this standard and ISO 17633.2010. Appendix B gives the corresponding technical differences and their causes.

Watch list.

This standard also made the following editorial changes.

--- Change the standard name to "Stainless Steel Flux Cored Wire";

--- Added Appendix C flux core wire type control (informative appendix);

--- Added Appendix E protective gas type code (informative appendix).

This standard is proposed and managed by the National Welding Standardization Technical Committee (SAC/TC55).
