Why choose ABRATIG Mo filler metal?
Choosing ABRATIG Mo as a filler metal is an excellent solution for welding certain low-alloy steels, especially those used in mechanically or thermally demanding environments. Here’s why we prefer it:
- Ideal for manganese-molybdenum (Mn-Mo) steels
The ER80S-D2 mainly contains :
-manganese (Mn) to improve mechanical strength and toughness,
-molybdenum (Mo) to enhance creep and hot fracture resistance.
–> Recommended for low-alloy steels such as AISI 4130, 4140, or steels used in boiler making, piping and mechanical engineering.
- Excellent mechanical strength
It produces welds with tensile strengths in the 550-700 MPa range, superior to conventional carbon steels.
- Good heat resistance
Thanks to its molybdenum content, ER80S-D2 welds hold up well at high temperatures, making it suitable for workpieces up to 500-600°C.
- Good heat treatment performance
Welds made with this filler metal accept post-weld heat treatment (PWHT), enabling mechanical properties to be adjusted as required.
