7 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations
JIS G 4305:2021, Table 3, heat analysis, mass fractions wt%; Each actual edition is retained separately. Applicable to cold-rolled stainless steel plate, sheet and strip; this does not establish suitability for delivery as cold-heading wire or guarantee cold-heading process performance. 5.2 product analysis permits variations under JIS G0321, Table 5; unlisted items require agreement between the parties; Heat-analysis limits are not directly widened in this batch. A dash indicates that no general limit is specified and is not treated as 0; Conventional welding carbon-equivalent formulas for low-alloy steels do not apply to this stainless steel category. Nb≥10×measured C; the original table specifies no general Nb maximum; Without measured C/Nb, compliance with the coupled requirement is not established.

Applicability and limitations
The original Japanese edition JIS G 4308:2013, Table 2, row 20, heat-analysis mass percentages. ; The standard covers hot-rolled stainless steel wire rod; Product-analysis tolerances must be checked under JIS G 0321 and purchaser requirements; tolerances are not included in the default heat-analysis range. ; Material designation and chemical composition do not establish cold-heading suitability or a supply commitment from Creation Group; Dimensions, delivery and processing condition require separate verification. ; Table 2 coupled condition: Nb≥10×C; no independent fixed minimum is specified, and no value is invented.
Verification notes
The grades in original Table 1–6, the heat-analysis table and footnotes were visually checked row by row; Nb≥10×C: the existing same-edition reference record retains ID and is superseded by the original standard table.SUS 347 · JIS G 4303-2005
