Supplier composition reference, not independently assayed chemistry or a statement of conformance to an unreviewed standard edition. Uses are the corresponding source application row, not a certified operating envelope. Ambiguous/mismatched AISI/DIN/JIS equivalence columns and reversed or unconditioned hardness values are omitted; no silently corrected standard values. No corrosion/temperature/safety approval or guaranteed final heat-treatment performance.
