Notes:

1. Indicate types of electrodes consist of index e (electrodes for arc welding) and next the numbers and letters. Two digits following the index to indicate the average carbon content in the deposited metal in hundredths of a percent. Chemical elements contained in the deposited metal, indicated by the following letters: A — nitrogen, B — niobium; tungsten; manganese; D — copper; M — molybdenum, N — Nickel; C — silicon, T is titanium; f — vanadium; X — chromium. The figures following the letter symbols of the chemical elements indicate the average content of the element in percent. After the letter designations of the elements, the average content in deposited metal is less than 1.50%, the numbers don’t bear. With the average content in the deposited metal of silicon up to 0.8% and manganese up to 1.6% of the letters C and G is not checked.

2. The mechanical properties of the weld metal and deposited metal for electrodes of types e-12H13, e-10Х17Т, e-12Х11НМФ, e-12Х11ВМФ, e-14Х11НВМФ, e-10Х16Н4Б, e-08Х246ТАФМ given after the heat treatment modes, regulated by the standards or specifications for the electrodes of specific brands, and for electrodes of other types in the as — welded (without heat treatment).
