ER70S-6

1 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：0.2933–0.5677 Envelope of independent element limits from manufacturer data; neither standard guarantee values nor measured heat results 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）：0.1567–0.3288Known-element contribution; incomplete value; missing 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：0.2000–0.3863 Envelope of independent element limits from manufacturer data; neither standard guarantee values nor measured heat results 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

China Steel bar and wire-rod catalogue CAT.NO.3-BD-01-2014-C1, PDF page 27

printed page 25, 7.1.21 ANSI/AWS A5.18-2005. The original catalogue does not explicitly identify the analysis type for this table. Historical manufacturer range data, not guaranteed standard limits or heat-specific measurements; this does not establish supply by Creation Group. Condition: Cu includes both copper plating and residual content, with total ≤0.50%; This does not represent chemical composition of the coating alone.

Composition conditions

Historical manufacturer 2014-C1 catalogue, bars/wire rod; Where the referenced standard edition is not identified, a year is not borrowed from another catalogue; a catalogue is not upgraded to the official standard text.
A dash or blank must not be treated as zero. Composition data do not establish completeness or applicability of a formula; mechanical properties and supply require separate verification.
Cu includes both copper plating and residual content, with total ≤0.50%; This does not represent chemical composition of the coating alone.

Verification notes

Merged cells in all 28 catalogue tables were reconstructed geometrically, with no missing cells. Original images, continuation pages and notes are recorded; disputed conditions are withheld.
