Inconel 800, 800H, and 800HT are nickel-iron-chromium alloys known for their excellent strength and resistance to oxidation and carburization at elevated temperatures. These alloys are commonly used in the production of seamless steel tubes for heat exchangers, where they provide superior performance in high-temperature environments.
ASTM B407 is the standard specification for seamless, cold-worked, and hot-finished nickel-iron-chromium alloy pipes and tubes. This specification covers the requirements for the chemical composition, mechanical properties, and dimensions of the tubes, ensuring they meet the necessary standards for industrial applications.
The chemical composition of Inconel 800, 800H, and 800HT is crucial for their performance. Below is a table presenting the typical composition:
| Element | Inconel 800 | Inconel 800H | Inconel 800HT |
|---|---|---|---|
| Nickel (Ni) | 30-35% | 30-35% | 30-35% |
| Chromium (Cr) | 19-23% | 19-23% | 19-23% |
| Iron (Fe) | 39.5% min | 39.5% min | 39.5% min |
| Carbon (C) | 0.10% max | 0.05-0.10% | 0.06-0.10% |
| Aluminum (Al) | 0.15-0.60% | 0.15-0.60% | 0.25-0.60% |
| Titanium (Ti) | 0.15-0.60% | 0.15-0.60% | 0.25-0.60% |
The mechanical properties of these alloys are essential for their application in heat exchangers. The table below outlines the typical properties:
| Property | Inconel 800 | Inconel 800H | Inconel 800HT |
|---|---|---|---|
| Tensile Strength (MPa) | 450 min | 450 min | 450 min |
| Yield Strength (MPa) | 170 min | 170 min | 170 min |
| Elongation (%) | 30 min | 30 min | 30 min |
The Inconel 800 series is classified under the nickel-iron-chromium alloy category, specifically designed to withstand high temperatures and corrosive environments. The grades 800, 800H, and 800HT differ mainly in their carbon content and annealing treatment, which affect their mechanical properties and suitability for different applications.
Inconel 800 series alloys are widely used in various industries due to their high-temperature capabilities and corrosion resistance. Common applications include:
While Inconel 800 series alloys are highly effective, alternative materials may be considered depending on specific requirements:
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
