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 rods for welding”.
Compared with GB/T 4241-2006, the main changes of this Standard are as follows.
- EXPAND the diameter range of wire rods from 5 mm ~ 20 mm in the original
standard to 4.5 mm ~ 20 mm;
- IMPROVE the requirements for mass of wire coils;
- DELETE 9 designations, i.e. H08Cr21Ni10, H03Cr21Ni10, H12Cr24Ni13,
H03Cr24Ni13, H12Cr26Ni21, H08Cr19Ni12Mo2, H03Cr19Ni12Mo2 with Si ≤ 0.35 %
and H06Cr14 and H08Cr11Nb that are unused for long periods; ADD 18
designations, i.e. H09Cr21Ni9Mn7Si, H16Cr19Ni9Mn7, H022Cr22Ni11,
H022Cr24Ni13Nb, H022Cr21Ni12Nb, H022Cr21Ni13Mo3, H022Cr26Ni21,
H022Cr20Ni16Mn7Mo3N, H022Cr19Ni12Mo2Nb, H022Cr20Ni10Nb,
H011Cr33Ni31MoCuN, H10Cr22Ni21Mo3, H022Cr25Ni9Mo3N, H10Cr12Nb,
H08Cr17Nb, H022Cr17Nb, H03Cr18Ti, 022Cr13Ni4Mo; the number of
designations is increased from 59 in the original standard to 68;
- Chemical composition analysis is modified from smelting analysis to finished
product analysis; CANCEL the allowable deviation of the chemical composition of
finished products;
- CANCEL the requirements for macrostructures in the standard, and MOVE it to
special requirements;
- ADD Annex A (normative) “Comparison between designations of this Standard and
designations of the original standard".
This Standard uses the re-drafting method to modify and adopt ISO 14343.2009
“Welding consumables - Wire electrodes, strip electrodes, wires and rods for arc
welding of stainless and heat resisting steels - Classification”.
For convenience of comparison, this Standard gives a table of comparison between
clauses of this standard and clauses of ISO 14343.2009 in Annex C.
According to China’s national conditions, this Standard has modified ISO 14343.2009
when adopting it. These technical differences are identified by the vertical single line
in the margins of the clauses in which they relate. A table of technical differences and
their causes is given in Annex D for reference.
This Standard is proposed by China Iron and Steel Association.
