G10080

5 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.

Table 1, general applications, including wire rod; Mn .30–.50%
IIW / CEV:0.0500–0.1833 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):0.0150–0.1250Known-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:0.0300–0.1500 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.
Note *: structural sections, plate, strip, sheet and welded tube; Mn≤.50%, with no minimum

Applicability and limitations

Original Table 1 UNS G10080 corresponds to SAE1008.; The two names are for retrieval correspondence.. ; Heat analysis wt%; Mn has no lower limit for structural sections/steel plates/strips/sheets/welded pipes; this is not automatically applied to wire rod.. ; Si is not a uniform mandatory component; When required, common ranges for bar products/semi-finished products are ≤ .10, .10–.20, .15–.35, .20–.40, .30–.60%; wire rod has a separate range of .07–.15%; No single range has been arbitrarily selected in this record. ; When Cu is required, it is generally specified as ≥.20%, which is not a uniform Cu upper limit or a default requirement. ; Addition of Pb .15–.35% requires L identification and a change to the UNS; Addition of B .0005–.003% requires B identification and shall not be merged into ordinary 1008.. ; Lower P/S for certain qualities/products must be verified separately per J411 and shall not apply agreement values from subsequent years. ; A requirement to report additional elements does not establish uniform limits for those elements in this table.; Unspecified Si/Cr/Ni/Mo etc. shall not be filled as zero; Finished product deviation to be verified separately per J409.
