Carbon-equivalent reference

IIW / CEV：0.4500–0.6267Known-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）：0.3833–0.4900Known-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：0.4100–0.5250Known-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 document, Table 1, heat analysis; PDF, page 3. The PDF main text lacks a cover and shows no standard number; The filename states “244—2019”; PDF was created in 2019, and this designation is not treated as a verified standard edition. G denotes Xingtai Steel high-end wire rod; -A/-B/-C is a quality-class suffix and must not be treated as boron B or aluminum-killed A. Check product-analysis tolerances under GB/T 222; This table gives heat-analysis ranges and must not be directly treated as guaranteed product-analysis ranges. This record does not establish Creation Group stock availability, customer approval or direct substitution. Table 1, merged residual-element cell: each Cr/Ni/Cu ≤0.20%. Clause 5.4: for high or relatively high cold-upsetting requirements, specimens with C at least 0.30% or containing alloying elements must first be spheroidize-annealed as specified in the clause; A range crossing the threshold requires assessment against the actual heat and contract.
