Carbon-equivalent reference

IIW / CEV:0.6360–0.8727Known-element contribution; incomplete value; missing Ni, Cu 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):0.4930–0.6370Known-element contribution; incomplete value; missing Cu, Ni, 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:0.5400–0.6730Known-element contribution; incomplete value; missing Cu, Ni 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

Table 3 of EN 10267:1998 is heat analysis mass fraction wt%. ; Table 1: Table 3 and Table 4 are used for untreated +U and cold-sheared +S deliveries; The chemical composition in Table 5 for precipitation hardening +P machined bars is for guidance only; Table 3 shall not be automatically regarded as a +P delivery guarantee. ; Table 3 Footnote 2: Other elements for improving machinability or controlling sulfides/oxides, as well as adjustments to the sulfur range, shall be by agreement. ; Table 3 Footnote 3: Partial or total substitution of V by Nb requires agreement; the lower limit of V must also be separately negotiated; Current composition reverse-checks shall only use the default limits of Table 3 without substitutions. ; Table 3 Footnote 4: Ti addition shall be by agreement; Elements not listed shall not be intentionally added without the buyer's consent (except additions needed to finish steelmaking). ; Product analysis deviations in Table 4 shall be verified separately; The +P mechanical properties in Table 5 correspond only to machined bars and 30–120mm; other sizes shall be by agreement; Cold-heading suitability shall be verified separately.

Verification notes

EN 10267:1998, Table 3, row 4, and Table 1 / footnotes were checked item by item; Composition in the +P condition is for guidance only.
