Applicability and limitations

Table 2 cast analysis, mass fraction wt%; Si is an upper limit and unspecified elements are not filled with zero. P/S requirements for the C, Ck and Cm series remain separate; S 0.020–0.035% in S-containing grades is a two-sided range. Note 1: unlisted elements may not be intentionally added without purchaser consent, except to complete melting; no fixed residual values are inferred. Table 3 contains permissible product-analysis deviations, not added to cast limits; applicable sizes and positive/negative directions are checked separately. Heat-treatment condition, hardenability and size-dependent properties require separate verification. The standard includes hot-rolled wire rod; chemistry alone is no cold-heading supply commitment. Note 2: small composition deviations, excluding P/S, may be agreed when ordering restricted hardenability bands or quenched-and-tempered/normalized properties, but may not exceed Table 3. These data retain the Table 2 baseline without automatic relaxation. Light-typeface grades in note 4 are for special applications only. Note 5 permits separate ordering of Pb 0.15–0.30% only for the marked C-series grades; not added to ordinary base compositions. Original material number 1.0501; not marked for special application under note 4.

Applicability and limitations

Q/BQB 130—2003 is a standard for slabs produced by initial rolling for subsequent rerolling. The finished plate thickness in Table 3 means the plate thickness after rerolling the slab, not slab thickness or wire diameter. Table 3 gives ladle analysis in mass fraction wt%; C = capped steel, A = aluminium-killed steel, G = aluminium-silicon-killed steel, K = silicon-killed steel. Read the applicable condition row; unlisted elements are not assumed to be zero. Note 3 to Table 3 requires slabs for thick plate (finished thickness ≥15 mm) to use G aluminium-silicon-killed steel; buyer and supplier must verify applicability of rows involving other deoxidation methods. Product-analysis tolerances for killed steel are separately governed by GB/T 222 and must not be mixed with Table 3 ladle-analysis values.

Applicability and limitations

The original informative-annex table has been checked and is for reference only. Clause 7.1.2 requires chemical composition to be determined under the cited standard; the formal normative composition and applicable edition remain unverified. Do not use it as a delivery guarantee, a reverse-search acceptance criterion or a basis for standard-range carbon equivalent.

Composition conditions

The original informative-annex table has been checked and is for reference only. Clause 7.1.2 requires chemical composition to be determined under the cited standard; the formal normative composition and applicable edition remain unverified. Do not use it as a delivery guarantee, a reverse-search acceptance criterion or a basis for standard-range carbon equivalent.
Footnote b: raising S to approximately 0.10% or adding Pb must follow the enquiry requirements; When S is increased, the Mn maximum may be increased by 0.15%; this is not applied automatically.
Footnote c: raising the S maximum to 0.005% requires agreement, sulfide treatment and Ca≥0.0020%; this is not enabled by default.
Footnote d: exemption from the N maximum requires Alt≥0.020%, acid-soluble Al≥0.015% or sufficient other nitrogen-binding elements, stated in the certificate; This is not enabled on the basis of missing Al.
Footnote e: Cu>0.40% may cause hot cracking during hot forming; Footnote f: reducing Si requires alternative deoxidation measures.
