Description

Description

Nickel Alloy Inconel 718 Pipes And Fittings is a precipitation-enhanced nickel-based high temperature and high strength alloy

Nickel Alloy Inconel 718 Pipes And Fittings has good comprehensive properties in the temperature range of -253 ~ 700 ℃, the yield strength of 650 ℃ or less is the first in the deformation superalloy, and has good anti-fatigue, anti-radiation, anti-oxidation, corrosion resistance, and good Processing performance, welding performance and long-term organizational stability, to create a variety of complex parts of the shape, in the aerospace, nuclear energy, oil industry, in the temperature range has been a very wide range of applications.
Another feature of the alloy is that the microstructure of the alloy is particularly sensitive to the hot processing technology, master the alloy phase precipitation and dissolution of the law and the organization and process, the relationship between the performance can be used for different requirements to develop a reasonable and feasible process, You can get to meet the different levels of strength and the use of various requirements of the parts.

Nickel Alloy Inconel 718 Pipes And Fittings has the following features:

1. Easy processing
2. High tensile strength, fatigue strength, creep resistance and breaking strength at 700 ℃
3. High oxidation resistance at 1000 ° C
4. Stable chemical properties at low temperatures
5. Good welding performance

Nickel Alloy Inconel 718 Pipes And Fittings metallographic structure:

718 alloy is austenitic structure, and the γ-phase formed by precipitation hardening has excellent mechanical properties, and the δ phase generated at the grain boundary during the heat treatment has the best plasticity.
Nickel Alloy Inconel 718 Pipes And Fittings corrosion resistance:
Whether in high temperature or low temperature environment, 718 alloy has excellent resistance to stress cracking and pitting ability. 718 alloy in the high temperature oxidation resistance is particularly good.

Nickel Alloy Inconel 718 Pipes And Fittings process performance and requirements:

Thermal processing
The appropriate hot working temperature is 1120-900 ℃, the cooling method can be water quenching or other rapid cooling method, after hot processing should be promptly annealed to ensure the best performance. Heat treatment materials should be heated to the upper limit of processing temperature, in order to ensure the plastic processing, deformation of 20% of the final processing temperature should not be less than 960 ℃.
Cold working
The cold working should be carried out after the solution treatment, the work hardening rate is greater than the austenitic stainless steel, so the processing equipment should be adjusted accordingly, and in the cold process should be intermediate annealing process
Nickel Alloy Inconel 718 Pipes And Fittings welding process
Alloy with a satisfactory welding performance, available argon arc welding, electron beam welding, seam welding, spot welding and other methods of welding.
Inconel718 parts heat treatment process
Heat treatment of aerospace parts is usually carried out according to the standard heat treatment system and the direct aging heat treatment system.
