1. Question: What are the primary applications of these alloys?
Inconel 800 & Incoloy 800HT: Used in chemical processing, petrochemical, nuclear, and heat exchanger components due to excellent high-temperature strength and oxidation resistance.
Inconel 825: Ideal for chemical, marine, and offshore industries because of its outstanding resistance to corrosion from acids and chloride environments.
Nickel Alloy Sheet: Commonly used in aerospace, electronics, chemical processing, and high-temperature applications requiring corrosion resistance.
2. Question: What are the typical mechanical and thermal properties?
Inconel 800: Tensile strength ~515–690 MPa; retains strength up to 700℃; good resistance to oxidation.
Incoloy 800HT: High tensile strength (~620 MPa) and excellent creep-rupture properties up to 850℃.
Inconel 825: Tensile strength ~515–690 MPa; excellent resistance to stress-corrosion cracking.
Nickel Alloy Sheet: Highly ductile, moderate tensile strength (~300–600 MPa), excellent resistance to chemical corrosion.
3. Question: What sizes and forms are available?
Available as sheets, plates, and strips.
Sheet thickness typically ranges from 0.5 mm to 10 mm, and standard sheet sizes are 1000 × 2000 mm or 1500 × 3000 mm, but custom sizes can often be provided.
Can also be supplied cut-to-size per customer requirements.
4. Question: How do these alloys perform in corrosive or high-temperature environments?
Inconel 800 & Incoloy 800HT: Excellent resistance to oxidation and carburization in high-temperature air and steam.
Inconel 825: Resistant to sulfuric, phosphoric, and hydrochloric acids, as well as chloride-induced stress corrosion cracking.
Nickel Alloy Sheet: Highly resistant to alkalis, oxidizing acids, and seawater.
5. Question: Are there any special processing or heat treatment requirements?
Inconel 800: Solution annealing recommended at 1038–1121℃, followed by air cooling to relieve stress.
Incoloy 800HT: Solution annealing at 1120–1175℃, air cooling; optional stress relief for welded components.
Inconel 825: Can be supplied in solution annealed condition; welding may require post-weld stress relief.
Nickel Alloy Sheet: Can be cold rolled or annealed for improved ductility and workability; no special heat treatment required unless specified.
