Table
Fluxes for SAW
[SI (Metric) Units]
FSXXX-ECXXX-HZ
F
Flux (virgin flux if not followed by S)
S
If present, flux is from crushed slag or blend of crushed slag and virgin flux.
X
Minimum tensile strength in units of 10 MPa (1.45 ksi)
43 = 430 MPa (62 ksi)
48 = 480 MPa (70 ksi)
X
Test condition of plates
A = tested as-welded
P = tested after postweld heat treatment
X
Temperature in oC at or above the impact strength meets or exceeds 27 J (20 ft-lbf)
Z = no impact requirements
0 = tested at 0oC ( 32oF)
2 = tested at -20oC ( -4oF)
3 = tested at -30oC (-22oF)
4 = tested at -40oC (-40oF)
5 = tested at -50oC (-58oF)
6 = tested at -60oC (-76oF)

E
Electrode
C
If present, electrode is Composite electrode. Electrode EC1 meets a chemistry
specified in A5.17. ECG does not have a specified chemistry. Either type must be
tested with a specific flux.
X
Manganese (Mn) content, % weight
L = low Mn (0.25 - 0.60)
M = medium Mn (varies by classification, 0.80 low to 1.50 high)
H = high Mn (varies by classification, 1.30 low to 2.20 high)
G = chemistry not specified
X
Number that makes up a part of the electrode classification system, indicating
chemistry in A5.17, Table 1. Generally, indicates nominal carbon content in
hundredths of a percent. Listed classification numbers: 8 (indicating 0.08%
nominal carbon), 11,12, 13, 14, and 15.
X
K indicates that the electrode was made from silicon-killed steel.
