Carbon-equivalent reference

IIW / CEV：0.4150–0.5917Known-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）：0.2608–0.3675Known-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：0.3250–0.4400Known-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. 3. 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%.
