2. In order to obtain the best performance and creep resistance, solid solution treatment should be carried out after hot working.

3. The material can be directly sent into the furnace which has been heated to 12℃, and then it can be quickly taken out of the furnace after holding the temperature for enough time, and then it can be hot-worked within the specified temperature range. When the material temperature drops below the hot working temperature, it needs to be reheated.

cold working

1. The work hardening rate is higher than that of austenitic stainless steel, so it is necessary to select the processing equipment. Cold working materials should be in solution heat treatment state, and intermediate annealing should be carried out when the cold working amount is large.

2. If the cold working amount is more than 1%, the workpiece needs secondary solution treatment.

Incoloy8 welding process

is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding and metal inertia gas, among which pulse arc welding is the first choice. If manual arc welding is used, (Ar+He+H2+CO2) is recommended as the shielding gas.
