Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 4241-2006 stainless steel wire rod for welding. This standard compared with GB/T 4241-2006, the main changes
as follows.
--- wire rod diameter range expanded from the original standard 5mm ~ 20mm modified to expand to 4.5mm ~ 20mm;
--- to improve the weight requirements of the coil;
--- remove the grades Si ≤ 0.35% of the H08Cr21Ni10, H03Cr21Ni10, H12Cr24Ni13, H03Cr24Ni13,
H12Cr26Ni21, H08Cr19Ni12Mo2, H03Cr19Ni12Mo2 and long-term use of H06Cr14 and
H08Cr11Nb a total of nine grades; increase the brand H09Cr21Ni9Mn7Si, H16Cr19Ni9Mn7, H022Cr22Ni11,

Ni9Mo3N, H10Cr12Nb, H08Cr17Nb, H022Cr17Nb, H03Cr18Ti, 022Cr13Ni4Mo and so on a total of 18 grades,
The number of grades increased from the original standard 59 to 68;
- Chemical composition modified by the smelting analysis for the finished product analysis, abolished the chemical composition of the finished product to allow deviation;
- Elimination of low-level organization requirements in the standard, moving it to special requirements;
- Added Appendix A (normative appendix) "This standard is a comparison with the original standard grade".
This standard uses the re-drafting method to modify ISO 14343.2009 "welding material stainless steel and heat-resistant steel arc welding welding wire, filling
Wire and welding tape classification ".
For convenience of comparison, this standard lists a list of the terms of this standard and the ISO 14343.2009 standard clause in Appendix C.
