High strength Incoloy800H nickel-based alloy round bar N08810 black bar 10-100mm anti-stress corrosion cracking.
Incoloy 800H is a nickel-based high-temperature alloy with good high-temperature strength, oxidation resistance and corrosion resistance. It is widely used in chemical, petrochemical, energy and nuclear energy industries. Its chemical composition is mainly based on nickel, iron and chromium, and also contains a small amount of molybdenum, copper, silicon and other elements. This alloy is usually used in high temperature environments and corrosive media, especially those applications that require good high temperature stability and oxidation resistance.
Incoloy 800H is a nickel-iron-chromium alloy, which is an improved version of 800 alloy and has a series of excellent physical and chemical properties. The following is a detailed description of Incoloy 800H material:
The main chemical components of Incoloy 800H include nickel (Ni), iron (Fe), chromium (Cr), aluminum (Al) and titanium (Ti), among which:
The nickel (Ni) content is between 30.0% and 35.0%.
The iron (Fe) content is at least 39.5%.
The chromium (Cr) content is between 19.0% and 23.0%.
The aluminum (Al) content is between 0.15% and 0.60%.
The carbon (C) content is between 0.15% and 0.60%.
| Ni | Fe | Cr | Al | C |
| 30.0%- 35.0%. | ≥39.5% | 19.0%- 23.0%. | 0.15% -0.60%. | 0.15% - 0.60%. |
In addition, the alloy also contains a small amount of manganese (Mn), sulfur (S) and phosphorus (P), among which the maximum manganese (Mn) content is 1.50%, and the sulfur (S) and phosphorus (P) contents do not exceed 0.015%. The reasonable combination of these elements gives Incoloy 800H alloy excellent oxidation resistance and corrosion resistance.
