HP10Cb

These consumables are designed for depositing weld metal that precisely matches the composition of similar castings. Derived from 800-type alloys, this alloy features increased chromium and nickel contents, resulting in enhanced resistance to carburization and oxidation. Operating effectively at temperatures up to 1100°C, it also exhibits remarkable resistance to thermal shock and fatigue. The consumables are particularly suitable for welding applications involving centrifugally cast pyrolysis coils, reformer tubes, return bends, and tees in the petrochemical industry. Typically, there is no need for preheating or post-weld heat treatment (PWHT), and it is advisable 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.
