Inconel600 alloy is a nickel-chromium-iron-based solid solution strengthened alloy.
Overview of characteristics and application areas: The alloy is a nickel-chromium-iron-based solid solution strengthened alloy with good high temperature corrosion and oxidation resistance, excellent cold and hot processing and welding properties, and satisfactory thermal strength below 700°C And high plasticity. The alloy can be strengthened by cold working, and it can also be connected by resistance welding, melt welding or brazing. It is suitable for making anti-oxidation parts with low load under 1100ºC

Inconel600 metallographic organization structure:
The alloy was treated at 1120°C for 2h, only TiN nitride and Cr7C3 type carbides, after long-term aging at 870°C at 1500°C, the structure is still Cr7C3 and TiN, indicating that the structure of the alloy is stable.
Inconel600 process performance and requirements:
1. The alloy has good hot workability, and the heating temperature for ingot forging is 1110ºC~1140ºC.
2. The average grain size of the alloy is closely related to the degree of deformation of the forging and the final forging temperature.
3. The alloy has good welding performance. It can be connected by various methods such as original arc welding, argon arc welding, resistance welding and brazing. Large or complex welded structural parts should be annealed at 870ºC for 1h after melting to eliminate welding. stress.
4. The alloy must be machined after heat treatment. Due to the work hardening of the material, it is advisable to use a lower alloy than the machined
5. The standard austenitic stainless steel has low cutting speed and re-entry tool for processing, so that it can be machined under the surface that has been cold-worked and hardened.
