SIDER 4122 Martensitic Stainless Steel Mig wire.

SIDER 4122 Martensitic Stainless Steel Mig wire for welding alloys of similar composition and for wear and corro¬sion 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.

Shielding gas : 100% Ar or Argon+2% O2 - 18·20 lit / min

Hardness of the pure weld deposit: 48-52 HRC
