Inconel 686 square plate
Inconel 686 square plate is a nickel-based superalloy. It is strengthened by adding chromium, molybdenum, tungsten and other elements. It has excellent corrosion resistance and high-temperature stability. The shape of Inconel 686 square plate is regular. The edges are precisely cut. The surface can be provided in hot-rolled, cold-rolled or polished finishes. The thickness and size can be customized. Common thicknesses are from 5 mm to 50 mm. The side length can reach up to 2000 mm.
Inconel 686 square plate is widely used in extreme environments. These include chemical applications like reactors and flue gas desulfurization. In marine engineering, it is used for deep-sea components and submarine equipment. In the energy sector, it is used in gas turbines and nuclear power. It is also used in semiconductor high-purity systems.
Inconel 686 square plate has excellent corrosion resistance, high-temperature resistance and high strength. These make it an ideal choice for high-demand industrial fields. However, it is expensive. It is suitable for key components with long service life.
Features of Inconel 686 square plate
Extreme environment tolerance:
Inconel 686 square plate resists chloride stress corrosion cracking (better than Inconel 625). It withstands acidic media (like sulfuric acid and hydrochloric acid). It also resists combined oxidation-reduction corrosion.
Inconel 686 square plate keeps its strength at high temperatures (up to 1200°C). It has excellent oxidation resistance.
Mechanical properties:
At room temperature, the tensile strength is at least 760 MPa. The elongation is at least 45%. Inconel 686 square plate has both high toughness and work hardening ability.
Process adaptability:
Inconel 686 square plate can be welded (with ERNiCrMo-14 filler wire) and hot-formed. But cold working needs annealing to avoid cracking.
Applications of Inconel 686 square plate
Chemical equipment:
Inconel 686 square plate is used to make hydrometallurgical reactors and the lining plates of flue gas desulfurization systems (FGD). It resists acid slurry erosion.
Marine engineering:
Inconel 686 square plate is used for the sealing surfaces of deep-sea pipeline flanges and submarine pressure-resistant parts. It deals with seawater high pressure and salt spray corrosion.
Energy field:
Inconel 686 square plate is used for the combustion chamber liners of gas turbines and the spent fuel handling devices in nuclear power. It ensures reliability in high-temperature and high-radiation environments.
Special manufacturing:
Inconel 686 square plate is used in the high-purity chemical delivery systems of the semiconductor industry. It avoids metal ion contamination.
