Inconel600 metallographic organization structure:

The alloy 2 h at 1120 ℃ treatment, only TiN, nitride and carbide Cr7C3 type, in the 870 ℃, 870 ℃ after aging for a long time, in the organization is still a Cr7C3 and TiN, show that the alloy tissue is stable.

Inconel600 process performance and requirements:

The alloy has good thermal performance, ingot forging heating temperature 1110 ℃ ~ 1140 ℃. 2, the grain size of alloy, average size and the degree of the deformation of the forging, finish forging temperature are closely related. 3, alloy has good welding performance, can the original electric arc welding, argon arc welding, resistance welding and brazing of various methods, such as connection, large or complex welding structure in the solution should be 1 h at 870 ℃ annealing after welding, in order to eliminate the welding stress. 4, alloy would take machining after heat treatment, due to the strain hardening material, so appropriate USES than processing low alloy
