A322 1340

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.

IIW / CEV:0.6467–0.8387Known-element contribution; incomplete value; missing V 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):0.4650–0.5723Known-element contribution; incomplete value; missing 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:0.5400–0.6597 Independent-element envelope of standard ranges; not measured heat-analysis values 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

Original header A322–91(Reapproved2001)e1; note e1 records correction of Table 1 in year 2004, month 5. The full edition is retained, not represented as 2013/2024. Cast analysis wt%. Note A gives maximum incidental contents for elements not otherwise specified or required: Cu≤.35/Ni≤.25/Cr≤.20/Mo≤.06; explicitly specified alloy ranges take priority. Note F: the purchaser may specify Si≤.10%, usually for severely cold-formed parts; default Si .15–.35%. Select the two conditions separately; this does not establish cold-heading supply availability. Note B: adding Pb .15–.35% requires L identification; not included in ordinary grades. This standard covers hot-worked alloy steel bars; coiled dimensions and applicability require supplier confirmation. Product deviations and other composition agreements referring to A29 require separate verification. Original-table UNS G13400; grade column 1340.
