SWCH22K

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.

IIW / CEV:0.2967–0.4700Known-element contribution; incomplete value; missing Mo, 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):0.2183–0.3200Known-element contribution; incomplete value; missing 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:0.2500–0.3600Known-element contribution; incomplete value; missing Mo 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

Wire-rod grade SWRCH22K; SWCH wire uses raw material complying with G3507-1, under G3507-2:2005 clause 3 note 1 and clause 4. This is not inferred from a similar grade. The website does not state the edition; the edition of this record’s source is shown, without establishing contractual applicability.

Applicability and limitations

JIS G 3507-2:2005, row 25 of the complete table; cast-analysis mass fraction %. SWRCH wire rod and SWCH wire are recorded separately. The chemistry of wire in Part 2 is based on the corresponding same-period raw wire rod in Part 1; D/DA wire mechanical properties cannot be inferred from it. Japanese original, Part 1, Table 2: Cr≤0.20%, residual Cu≤0.30%, Ni≤0.20%; dashes are not filled with zero. The Chinese translation incorrectly gives the carbon maximum for SWRCH15K as 0.15 and omits ≤ in the R-category sulphur column; the corresponding Japanese-original values 0.18 and ≤0.040 are retained here. Sources for the 2005 and 2021 editions are kept separate; identical grade names do not establish the contractual edition or supply by our company.

Verification notes

All 38 rows of Table 2 were compared value by value with the 2021 edition of the Japanese original; two layout errors in the Chinese translation were corrected against the Japanese original.
