Description:
Cromatig LDX is designated for MIG welding of all lean duplex materials, i.e. molybdenum free duplex
grades such as 4062, 4162 and 4362.
The product ensures a weld metal with a high strength and medium corrosion resistance, compatible
with the base material.
Applications:
For applications with EN 1.4062, EN 1.4162 (ASTM S32101) or EN 1.4362 (ASTM S32304) base
materials. The steels are mainly used in civil engineering, storage tanks, containers etc.

Corrosion resistance
General corrosion
Thanks to its high Cr content (> 23%) the
Cromatig LDX allows welds with a general
corrosion resistance at least equal to the one of
the plates on which it is used for welding, in
particular the 4062 grade with 22% Cr and the
4162 grade with 21% Cr.
Pitting corrosion
For the 6%FeCl3 medium (ASTM G48A
standardised test), the critical pitting temperature
of the above-described welded joint is determined,
by calculation, to 16°C, i.e. 10°C above the level
measured for a base metal of the 304L/1.4307
type and at the same level as that of a base metal
of the 1.4362 type.
Intergranular corrosion
As all the low C Duplex grades, in the as-solidified
condition, the Cromatig LDX does not exhibit, on
duplex welded joint, any intergranular precipitation
likely to cause intergranular corrosion phenomena.
