Carbon-equivalent reference

IIW / CEV:0.1417–0.3417 Known-item contribution, not a complete value; missing Cr, Mo, V, 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):0.0425–0.2075Known-element contribution; incomplete value; missing Si, Cu, Cr, Ni, 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:0.0850–0.2650 Known-item contribution, not a complete value; missing Mo, Cr, 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

ASTM A576-17 applies to hot-finished bars of quality carbon steel; Table 1 specifies heat analysis; This must not be assumed to guarantee the performance of wire rod or finished cold-heading products.. ; Table 1 Note C: Si shall be according to order agreement when required, commonly ≤0.10, 0.10–0.20, 0.15–0.35, or 0.20–0.40%.; Do not enter a fixed Si value if not agreed upon. ; Table 1 Note D: When Cu is required, Cu≥0.20% may be specified, which is a conditional requirement.. ; Notes E/F/G: Pb, B, and Bi/Ca/Se/Te are all applicable only when specified.; Do not automatically add Pb/B lower limits to all grades. ; Clause 7.1 requires reporting the content of Cu/Cr/Ni/Mo/V/Nb; the reporting requirement is not equivalent to the provision of limits for these elements in Table 1.. ; Clause 5.1 allows other chemical ranges to be agreed upon according to Table 2.; Table 2 does not impose additional mandatory limits on every grade in Table 1.. ; Table 1, Note H: These grades are usually not produced to the specified Si limits for machinability reasons; do not infer a Si range..
