Applicability and limitations
JIS G 4305:2021, Table 5, 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. Original table note: where unspecified Cu/V/Ti/Nb is added as needed, its content must be reported; No general limit is specified; a guaranteed range is not invented.
