SUS434
3 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 4308:2013, Japanese original, Table 4, row 4, cast-analysis mass fraction %. The standard covers stainless-steel hot-rolled wire rod. Product-analysis deviations must be checked under JIS G 0321 and purchaser requirements; deviations must not be added to the default cast-analysis range. Grade designation and chemistry do not establish cold-heading suitability or a supply commitment by our company; dimensions, delivery and process condition require separate verification.

Applicability and limitations
The original scanned Japanese edition JIS G 4308:1998 lists SUS434 in main-text Table 1; main-text Table 3 gives heat-analysis mass percentages. ; This edition covers stainless steel wire rod; reference suffix -WR is not a separate default grade; Standard wire diameters are in Table 6; product-analysis tolerances require separate verification under Clause 4.2. ; Table 3, remark: Ni≤0.60% is a permitted-content condition, not a default composition. ; This does not establish cold-heading suitability, stock dimensions or a supply guarantee from Creation Group.
Verification notes
Line-by-line visual check of Table 1 and Tables 2–5 in the 1998 scanned Japanese original; footnote conditions are kept separate from the default composition.SUS434 · JIS G 4305-2021

Applicability and limitations
JIS G 4305:2021, Table 5, heat analysis, mass fraction 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 performance. 5.2 product analysis permits variations under JIS G0321, Table 5; unlisted items require agreement between the parties. These variations are not added to the heat-analysis limits in this batch. A dash indicates that no general limit is specified; it is not treated as 0. Conventional welding carbon-equivalent formulas for low-alloy steels do not apply to this stainless steel category.
