Why choose ABRATIG CrMo1 filler metal?
Choosing ABRATIG CrMo1 as a filler metal is justified in well-defined technical contexts, particularly when working with chromium-molybdenum alloyed steels. Here’s why it’s the right choice:
- Suitable for CrMo steels (e.g. 13CrMo4-5, 16Mo3)
TIG CrMo1 is formulated for welding low-alloy steels containing :
-chromium (Cr) for resistance to oxidation and corrosion,
molybdenum (Mo) for high-temperature creep resistance.
–>It ensures excellent metallurgical compatibility and continuity of mechanical properties in the welded zone.
- Excellent high-temperature resistance
This filler metal is designed for high-temperature applications, such as :
-boilers,
high-pressure steam pipes,
-heat exchangers,
-chemical reactors.
It retains its mechanical strength up to 500-600°C
- Good creep and thermal fatigue resistance
Welds made with TIG CrMo1 resist repeated stresses (heating/cooling cycles), and long-term creep – crucial for installations in continuous service.
- Good suitability for post-weld heat treatment (PWHT)
CrMo steels often require heat treatment after welding. ABRATIG CrMo1 is designed to withstand such annealing without loss of performance or cracking.
