SUS303SE
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.

Applicability and limitations
The original Japanese edition JIS G 4308:2013, Table 2, row 4, heat-analysis mass percentages. ; The standard covers hot-rolled stainless steel wire rod; Product-analysis tolerances must be checked under JIS G 0321 and purchaser requirements; tolerances are not included in the default heat-analysis range. ; Material designation and chemical composition do not establish cold-heading suitability or a supply commitment from Creation Group; Dimensions, delivery and processing condition require separate verification. ; Table 2 separately lists Se composition, recorded as in the original table.

Applicability and limitations
JIS G 4308:1998: main-text Table 1 in the scanned Japanese original lists SUS303Se; main-text Table 2 gives heat analysis, mass fraction %. This edition covers stainless steel wire. The reference suffix -WR does not create another default grade. Standard wire diameters are given in Table 6; product-analysis deviations under clause 4.2 require separate verification. Cold-heading suitability, stocked sizes and supply by our company are not automatically established.
