SIDER 4122 Hardfacing SAW wire.

SIDER 4122 Hardfacing martensitic SAW wire for wear and corrosion resistant hardfacings.
Application field
SIDER 4122 is suitable for high-grade buildups on non-and low alloyed base steels / kinds of steel and tool steels.
Application fields are sealing faces on fittings, plungers and claddings on rotors.
The martensitic welding deposit has a high wear resistance also at elevated temperatures as well as a good resistance against water, steam and diluted organic acids. Scale resistant up to 900° C.
Welding instruction:
Clean welding area to metallic bright.
Preheating temperature 150 - 400° C, depending on the size of the work piece and the base material. Slow cooling and, if necessary, tempering.

Hardness of the pure weld deposit: 48-52 HRC
Average Wire Analysis in %:
