Applicability and limitations
JIS G 4309:2013: main-text Table 1 of the Japanese original lists tempers SUS310S and W1, classified as austenitic stainless steel. Main-text Table 2: W1 applies to wire diameters 0.020–14.0 mm; W1/W2/W1/2H must not be mixed. Main-text clause 4 references the chemical-composition requirements in clause 5 of JIS G 4308 or JIS G 4311. Annex JA gives wire-rod composition references only, not independent mandatory limits for the finished wire. Mechanical properties by wire diameter and Annex JA composition have not been entered condition by condition in this record; no supply or performance guarantee is inferred. Existing composition remains a reference transcription and has not been upgraded to cell-by-cell original-source verification.
