SUS 405
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 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.

Applicability and limitations
A material-database match does not establish cold-heading suitability or a finished-product strength commitment; Confirmation requires the actual wire condition, reduction, heat treatment and physical testing. ; The original Japanese 2005, Table 1 confirms this bar-grade designation; Composition and property sources require separate verification under Table 2—6 and the applicable condition.

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.
