Solid wire, high-alloyed, high corrosion resistant

Avesta 253 MA is designed for welding the high temperature steel Outokumpu 253 MA, used for example in furnaces, combustion chambers, burners etc. Both the steel and the consumable provide excellent properties at temperatures 850 – 1100 °C. MIG welding of 253 MA is best performed using spray arc or pulsed arc. 253 MA has a tendency to give a thick oxide layer during welding and hot rolling. Black plates and previous weld beats should be carefully brushed or ground prior to welding.

Structure: Austenite with 3 – 10 % ferrite.
Scaling temperature: Approx. 1150 °C (air).
Corrosion resistance:
Excellence resistance to high temperature corrosion. Not intended for applications exposed to wet corrosion.
