EN ISO CODE:
A Martensitic Stainless Steel OA wire for CC Roll Rebuilding
LoTherme OA-444L deposits a martensitic weld metal with 13%Cr - 4%Ni - 0.5%Mo. It has excellent resistance to cracking and good resistance to corrosion, erosion, abrasion and pitting. It has good resistance to metal-to-metal wear & galling and also heat resistant up to 950°C.
Ideally suited for welding of similar composition alloyed steels and cast steels. Typical applications include repair welding of hydro turbine components, continuous casting rolls, surfacing of highpressure valves, turbine blades, valve seats, repair of runners, pulp and paper plant equipment, etc.
Weld Metal Hardness: 40 - 45 RC
|Current Range (Amps)||200-300||250-350|
