Weldability and chemical composition reinforcing steel bars according to Β500C ΕΛΟΤ ΕΝ 10080

Weldability is determined by two characteristics:
- carbon equivalent
- limitations on the content of certain elements.

The maximum values of individual elements and the carbon equivalent must not exceed the values given in Table 2.

The carbon equivalent value Ceq is calculated using the following formula:
Ceq = C+ Mn/6 + (Cr+Mo+V)/5 + (Ni+Cv)/15
where the symbols of the chemical elements indicate their content in % by mass.

Mn: Manganese
Cr: Chromium
Mo: Molybdenum
V: Vanadium
Ni: Nikel
Cu: Copper
