תיאור של Inconel 625


Inconel625 is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strengthening elements. It has excellent corrosion resistance and oxidation performance. It has good tensile properties and fatigue properties from low temperature to 980 ℃, and is salt-resistant Stress corrosion in a foggy atmosphere.

תיאור של Inconel 625. -PTJ מכונות CNC חנות

Therefore, it can be widely used to manufacture aero engine parts, aerospace structural parts and chemical equipment. The alloy has good processing and welding performance, and can supply various plates, bars, pipes, wires, strips and לְטִישָׁהs.

Alloy 625 is a corrosion-resistant, oxidation-resistant nickel-based alloy. The excellent strength and toughness of 625 alloy in the low temperature-1093 ° C temperature range is derived from the solid solution effect of the refractory metal colium and molybdenum in the nickel-chromium matrix. The excellent fatigue strength and resistance to stress corrosion cracking of 625 alloy benefit from the chloride ion in the material.


Inconel 625 application

625 alloy is mostly used for manufacturing heat shields, turbine engine air ducts, internal combustion tubes, fuel injection rods, chemical industry equipment and special seawater applications.


Inconel 625 Corrosion resistance

625 alloy can withstand a variety of corrosive environments. In alkaline solutions, sea water, fresh water, neutral salts and air, the material has little corrosion. Nickel and chromium components provide antioxidant capacity. Nickel and molybdenum provide resistance to corrosion by non-oxidizing gases. Molybdenum can effectively prevent pitting and crevice corrosion. The resistance to chloride stress corrosion cracking is particularly prominent. At high temperatures, 625 alloy is not prone to flaking or oxidation.

טיפול בחום

There are three basic heat treatment methods for 625 alloy:
1. High solution annealing: 1093-1204 ° C, air quenching or faster quenching
2. Low solution annealing: 927-1038 ° C, air quenching or faster quenching
3. Stress relief: 899 ° C, air quenching
 
The heat treatment time depends on the number of materials and the thickness of the cross section. The heat treatment time of methods 1 and 2 is usually 1 / 2-1 hour, and the heat treatment time of method 3 is 1-4 hours.
 
When the working temperature is above 816 ° C and the creep resistance is more important, Method 1 is usually used to process the material. Steel mills will also use high solution annealing to make the material soft and easy to cold-roll or cold-draw.
 
Method 2 is the most commonly used heat treatment method. 1038 ° C can optimize the comprehensive performance of tensile strength and cracking strength. At the same time, the ductility and toughness under low temperature environment are also very good.
 
When the working temperature is below 649 ° C, when the requirements on the fatigue resistance, tensile strength, yield strength and hardness of the material are high, Method 3 is recommended for heat treatment. The treated material has very good ductility and toughness in low temperature environment. If dense grains are required, the material will have good fatigue strength, tensile strength and yield strength in the environment below 816 ° C. Sometimes method 3 can also be used.

The maximum furnace temperature for thermal processing is 1149 ° C. Take care to avoid the accumulation of frictional heat that can cause overheating to exceed 1149 ° C. Alloy 625 will become more rigid below 1010 ° C. If it is below this temperature, the workpiece needs to be reheated. It is recommended to perform uniform forging to avoid mixed crystal structure. The finished forging rate is about 15-20%.


Cold Processing

625 alloy is suitable for a variety of standard cold working methods. After cold working, the workpiece becomes rigid and can be restored to its ductility by annealing.

High-speed steel cutting speed

מה זה Inconel 625 						 							2020-05-16

The angle of the carbide tool is smaller than that of the HSS tool, and the cutting speed is faster.
It is recommended to use sulfur-based cutting fluid. After machining, it is necessary to thoroughly clean the workpiece to avoid bringing surface contaminants into the subsequent heat treatment process.

Gas welding can be used for welding, tungsten electrode or consumable metal electrode. No post-weld heat treatment is required to maintain corrosion resistance. Before welding, pay attention to clean the welding surface and align the welding seam. The thick welding area adopts U-shaped welding method.
