SUS430
2 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.

Composition
| Element | Composition requirement |
|---|---|
| C | ≤ 0.12 (lower limit not stated) |
| Si | ≤ 0.75 (lower limit not stated) |
| Mn | ≤ 1.0 (lower limit not stated) |
| P | ≤ 0.04 (lower limit not stated) |
| S | ≤ 0.03 (lower limit not stated) |
| Cr | 16.0 ～ 18.0 |
Applicability and limitations
The original scanned Japanese edition JIS G 4308:1998 lists SUS430 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.SUS430 · Japanese standard (number not stated)

Applicability and limitations
A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
