Table footnote a: residual Cr≤0.20, Ni≤0.20, Cu≤0.20, Mo≤0.06 wt%; where this row specifies otherwise, its requirement for that element takes precedence. Unlisted elements and special agreement requirements must not be treated as zero or assumed guarantees; permitted product-analysis deviations are governed separately by GB/T 222. Wire rod is delivered hot rolled; stricter P/S under Z1 and special surface or inclusion quality must be confirmed under normative Annex A and the contractual ordering codes. Fixed mechanical properties must not be inferred from the chemistry table.

Applicability and limitations
Baosteel BEXG 021-2020, Table 1, row 11, PDF page 4; heat-analysis composition in wt%, hot-rolled wire rod. 2020 is the original edition available locally, with no claim that it is the company’s current latest edition. Special conditions and actual supply require separate confirmation.
Composition conditions
- Table 1 and its continuation give heat composition, in mass fractions wt%; The product is hot-rolled wire rod for automotive parts.
- Unless expressly stated otherwise, residual Cr≤0.20%, Ni≤0.20%, Cu≤0.20% and Mo≤0.06% apply; Specific requirements in the table and additional notes take precedence.
- A dash does not mean zero; Composition outside the table is not inferred from grade names or referenced standards.
