Applicability and limitations
Mass fraction wt%; Q/XG 232-2021, Table 1, heat analysis; Local PDF, page 3. Table 1 merged cell: P≤0.030%, S≤0.030% and B 0.0008%–0.0030% apply to all 17 rows. Clause 4.1.2: residual Ni and Cu are each ≤0.20%, Cr≤0.30%. Check product-analysis tolerances under GB/T 222; Heat-analysis ranges are not directly treated as guaranteed product-analysis ranges. Clause 4.1.3: other compositions may be supplied by agreement between both parties and are not automatically included in Table 1. Xingtai Steel wire-rod enterprise-standard record; this does not establish Creation Group stock availability or a project-approved substitute. Table 1: Alt≥0.02%; Applies only to the first 5 rows.
