Carbon-equivalent reference

IIW / CEV：0.1300–0.2967Known-element contribution; incomplete value; missing Mo, V CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15; an engineering estimate of welding cold-cracking susceptibility for carbon and low-alloy steels.

Pcm（Ito–Bessyo）：0.0990–0.2017Known-element contribution; incomplete value; missing Mo, V Pcm = C + Si/30 + (Mn + Cu + Cr)/20 + Ni/60 + Mo/15 + V/10 + 5B; mainly used for low-carbon low-alloy steels, particularly modern low-carbon pipeline steels; more relevant when C is approximately no higher than 0.11%.

CET：0.1100–0.2150Known-element contribution; incomplete value; missing Mo CET = C + (Mn + Mo)/10 + (Cr + Cu)/20 + Ni/40; used in welding preheat assessment for ferritic steels, subject to the applicability conditions of EN 1011-2.

Applicability and limitations

Mass fraction wt%; Q/XG 231-2023, Table 1, heat analysis; Local PDF, page 4. Check product-analysis tolerances under GB/T 222; Heat-analysis ranges are not directly treated as guaranteed product-analysis ranges. Clause 5.1.4: residual Cr, Ni and Cu, where no separate range is specified, are each ≤0.20%. Clause 5.1.3: other grades or compositions may be supplied by agreement between the parties and are not automatically included in Table 1. This table is an enterprise standard for Xingtai Steel wire rod; it does not establish Creation Group stock availability or a project-approved substitute. Table 1, note 1: the XGSWRCH series references the grade-designation system of JIS G3507; Composition values follow Table 1 of this Xingtai Steel standard. Table 1, note 2: A means aluminum-killed; Alt≥0.02%. Table 1: B is 0.0008%–0.0030%, not unspecified.
