China vervaardiger spesiale staal hoë kwaliteit nikkellegering Incoloy 800 pypplaatplaatstaaf

The Cr content in incoloy800 alloy is usually 15-25%, nickel content is 30-45%, and contains a small amount of aluminum and titanium. The 800 alloy is in the austenite single zone after high temperature and rapid cooling, therefore, the use state is a single austenite structure. The alloy has a high chromium content and a sufficient nickel content, so it has a high resistance to high temperature corrosion, and is widely used in industry. In chloride, low concentration NaOH aqueous solution and high temperature and high pressure water, it has excellent stress corrosion cracking resistance, so it is used to manufacture stress corrosion cracking resistance equipment.

Incoloy 800 has anti-oxidizing medium corrosion, and has good kang carburizing performance at high temperature. Uses: Heat exchanger, steam generator tube, etc. The temperature resistance can reach 1100°C.

Incoloy 800/800H
ASTM B 409, B 408, B 407, B 564
UNS-nommer N08800
Other common names: Alloy 800, Alloy 800H, Inconel 800, Alloy 800HT

Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has further modifications to the combined titanium and aluminum levels (.85-1.20%) to ensure optimum high temperature properties.The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties.
