Inconel718 Inconel alloy wire mesh characteristics, technical parameters, features, applications

Inconel718 Inconel alloy wire mesh is also known as Inconel718 Inconel alloy wire woven mesh, Inconel718 Inconel alloy wire screen, Inconel718 Inconel alloy wire filter, Inconel718 Inconel alloy wire screen. Inconel718 Inconel alloy wire
mesh is a kind of nickel-based high-temperature alloy. Nickel-based high-temperature alloy is a high-temperature alloy with nickel as the matrix (the content is generally greater than 50%) in the range of 650-1000℃ with high strength and good oxidation resistance and gas corrosion resistance.

Inconel718 Inconel alloy wire metallographic structure
Alloy 718 is an austenite structure, and the γ" phase generated after precipitation hardening gives it excellent mechanical properties. The δ phase generated at the grain boundary during heat treatment gives it excellent plasticity.
Inconel718 Inconel Alloy Wire Corrosion Resistance
Whether in high or low temperature environments, alloy 718 has excellent resistance to stress corrosion cracking and pitting. The oxidation resistance of alloy 718 at high temperatures is particularly outstanding.
Processing performance and requirements
Hot working
1. The hot working temperature range is 1200℃～900℃, and the cooling method is water quenching or rapid air cooling.
2. To obtain the best corrosion resistance and the most suitable crystal structure, heat treatment must be performed after hot working.
3. The material can be directly sent to the heated furnace.
Cold working
1. The cold working material should be annealed or solution heat treated. The work hardening rate of alloy 600 is close to that of austenitic stainless steel, so similar processing equipment can be selected.
2. Intermediate annealing should be performed during the cold working process.
3. When the cold working amount is greater than 5%, the workpiece needs to be solution treated.
4. To reduce material wear, the mold should be made of alloy tool steel, cemented carbide or cast steel.
Welding process
The alloy has good welding performance and can be connected by various methods such as arc welding, argon arc welding, resistance welding and brazing. Large or complex welded structures should be annealed at 870℃ for 1h after fusion welding to eliminate welding stress.
Parts heat treatment process
The heat treatment process of parts should be carried out according to the heat treatment system of the corresponding material standard. Annealing of thin plate and strip parts should be carried out in a protective atmosphere.
Application range
Due to its high temperature strength, excellent corrosion resistance and easy processing at 700℃, 718 can be widely used in various high-demand occasions.
A. Steam turbine
B. Liquid fuel rocket
C. Cryogenic engineering
D. Acidic environment
E. Nuclear engineering
