1 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.

Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Carbon-equivalent reference

IIW / CEV：0.2300–0.3967Known-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）：0.1600–0.2517Known-element contribution; incomplete value; missing Mo, V, B 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：0.1900–0.2950Known-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%; manufacturer file, Table 1 ladle analysis; PDF p. 2. The PDF body has no cover and no standard number was found; the filename says “244—2019” and the PDF was created in 2019, which does not establish a verified standard edition. G denotes Xingtai Steel high-grade wire rod; suffixes -A/-B/-C are quality grades, not boron B or aluminium-killed A. Product-analysis tolerances are checked under GB/T 222; this table is a ladle range, not directly a guaranteed product range. This record does not represent our stock, customer approval or direct substitutability. Table 1 residual-element merged cells: Cr/Ni/Cu each ≤0.20%.
