Why choose ABRATIG 28 filler metal?
Choosing ABRATIG 28 as a filler metal is a targeted technical choice for welding super-austenitic stainless steels, like Uranus S28 itself, or other closely related alloys such as 904L, 254 SMO, 1925 hMo, etc.
Here’s why it’s an excellent choice:
- Perfectly compatible with Uranus S28 steel
ABRATIG 28 has a chemical composition similar to that of the base metal: rich in nickel, chromium, molybdenum, copper and nitrogen. This ensures optimum metallurgical continuity, with uniform corrosion resistance.
- Excellent resistance to severe corrosion
Thanks to its alloy elements, it withstands :
-strong acids (sulfuric, phosphoric, etc.),
-chlorinated environments (salt water, acid gases),
-pitting, crevice and intergranular corrosion.
–>Ideal for chemicals, flue gas treatment, offshore industry, etc.
- Good heat resistance and structural stability
It retains its mechanical and chemical properties up to around 400-500°C, without harmful precipitation, which is crucial in critical installations.
