Inconel686

Inconel 686 is a NI-Cr-Mo solid solution reinforced corrosion resistant nickel-based alloy with jie out corrosion resistance in harsh corrosive environments, mainly used in chemical treatment, pollution control, paper, industrial and municipal waste treatment, such as heat exchangers, reaction vessels, transport pipes, etc.

Inconel686 corrosion resistant alloy application areas. 1. Thermocouple sleeves in aggressive atmosphere 2. Vinyl chloride monomer production: resistance to chlorine gas, hydrogen chloride, oxidation and carbonization corrosion 3. Uranium oxidation conversion to hexafluoride: resistance to hydrogen fluoride corrosion 4. Production and use of corrosive alkali metals, especially in environments using sulfur compounds 5. Titanium dioxide production by chlorine gas 6. Production of organic or inorganic chlorides and fluorides: resistance to corrosion by chlorine and fluorine gas 7. Nuclear reactors 8. Heat treatment furnaces with curved neck bottles and components, especially in carbonizing and nitriding atmospheres 9.Catalytic regenerators in petrochemical production are recommended to use alloy 686 in applications above 700°C to obtain a long service life. Inconel 686 corrosion resistant alloy characteristics. 1. has very good resistance to reduction, oxidation, nitrogenation medium corrosion performance 2. good resistance to stress corrosion cracking at both room temperature and high temperature 3. good resistance to dry chlorine and hydrogen chloride gas corrosion 4. good mechanical properties at sub-zero, room temperature and high temperature 5. very good creep fracture strength, recommended for use above 700°C Inconel686 corrosion resistant alloy physical properties (room temperature).

According to the U.S. Huntington Special Materials Company, Inconel 686 alloy with your different corrosion resistance characteristics has replaced the U.S. Navy ships used K 500 alloy as a connector. Alloy 686 is a solution-reinforced alloy that achieves high strength through cold working. In particular, cold worked 686 alloy shows outstanding resistance to hydrogen embrittlement and corrosion, such as excellent strength, ductility and toughness. Bolts of 1.3 x 33 cm (0.5 x 13 in.) made from cold worked 686 alloy bars with a diameter of 38 in (15 in.) have a standard R1Tr ji tensile strength of 993 MPa, and these machined bolts show good performance in the middle of the machined joint and wedge tension tests. Inconel 686 process properties and requirements. Hot processing 1. Hot processing temperature range 1200 ℃ ~ 900 ℃, cooling method for water quenching or rapid air cooling 2. To get the zui best corrosion resistance and zui suitable crystal structure, heat treatment after hot processing 3. The material can be directly fed into the furnace which has been heated up Cold working 1. cold working material should be annealed or solution heat treated state, the work hardening rate of 686 alloy is close to that of austenitic stainless steel, so you can choose similar processing equipment 2. In the process of cold working volume should be intermediate annealing 3. In the cold working volume is greater than 5%, then the workpiece needs to be solid solution treated 4. To reduce the wear of the material, the tool should be selected from alloy tool steel, carbide or cast steel
