HP10Cb

This electrode is specifically designed for depositing filler metal intended for castings with similar composition. The alloy, developed based on type 800 with increased chrome and nickel content, offers superior resistance to both carburization and oxidation. It is suitable for use at temperatures up to 1100 °C and ensures excellent resistance to thermal shock and fatigue. The main applications include welding of centrifugally cast pyrolysis coils, reformer tubes, return bends, and tee connections in the petrochemical sector. Generally, neither preheating nor post-weld heat treatment (PWHT) is required, while it is recommended to maintain interpass temperatures below 150 °C.

0.1%C-25%Cr-35%Ni-0.6%Nb (HP10Cb) austenitic cast alloy for heat resisting service.

In the as-welded condition the weld metal microstructure consists of austenite with some grain boundary carbides.
