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. The original table permits one or a combination of Ti, Nb and Zr; The total of the actually selected elements is ≥8×(C+N) and ≤0.80%; The branch checks only measured values for the actual selected route; it does not invent independent lower and upper limits or treat unreported elements as 0. Original table note: where unspecified V is added as needed, its content must be reported; No general limit is specified; a guaranteed range is not invented.
