SWRS62B

2 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

Estimate from manufacturer-published ranges, not a standard guarantee or measured heat result; formula applicability requires review against the application and process.

IIW / CEV：0.7000–0.8133Known-element contribution; incomplete value; missing Cr, Mo, V, Ni 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）：0.6340–0.7157Known-element contribution; incomplete value; missing 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：0.6600–0.7500Known-element contribution; incomplete value; missing Mo, Cr, 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

Locally held POSCO wire rod catalogue, PDF page 9

printed page 17, table index 1, row 2. The original edition number is not stated. The PDF creation date 2014-12-03 is not a standard publication year. Manufacturer range data do not constitute our company’s supply guarantee.

Composition conditions

Original catalog chemical composition table %, wire rod; Editions of JIS/SAE/DIN were not provided; catalog data shall not be upgraded to the verified official editions of these standards.
Dashes are not zero; cast/product analysis types are not consistently explicit. Orders, product-analysis deviations and actual supply require separate verification.

Verification notes

The original PDF tables and text coordinates were reconciled in both directions. Missing grade cells were restored; merged cells, footers and remarks were checked separately. Tables with identified disputes and rows without composition data are withheld.
