inconel600 (n06600) nickel-based alloy overview
Inconel600 is an early developed Ni-Cr-Fe-based solid solution reinforced alloy. It has good resistance to high temperature corrosion and oxidation resistance, and excellent hot and cold processing and welding process performance. It has good thermal strength and high plasticity below 700°C. The alloy can be strengthened by cold processing or connected by resistance welding, solution welding or brazing. It can be used for cold-rolled thin plates, hot-rolled thick plates, strips, wires, rods, round cakes, ring blanks, ring forgings, etc. Suitable for the manufacture of oxidation-resistant parts with low loads below 1100°C.

① The plates in the supply state should undergo room temperature bending test. The diameter of the mandrel is equal to the product thickness multiplied by the bending coefficient in Table 3-2. The bending shaft should be parallel to the rolling direction. After bending 180°, zoom in 20 times to check the bending axis and no cracks are allowed.
