- Table 1 mass fraction %, default is heat analysis.
- Note a: Si is not specified; it may be agreed to use ≤0.10%, 0.10–0.20%, 0.15–0.35%, etc.; The listed items are not the only possible agreed ranges.
- Note b: Without agreement between both parties, elements not specified shall not be intentionally added for purposes other than to finish steelmaking; Blank entries must not be treated as zero.
- Note c: Only SUM22/SUM22L may have an agreed Mn upper limit of 1.10%.
