What is Incoloy?
Incoloy is a nickel-iron-chromium alloy that is part of the 800 series. One such advantage is the ease with which it can be manufactured, as it uses the same machinery and methods as stainless steel. While Incoloy in its basic form is widely used, further alloying with enhancing elements provides additional resistance to chemical and environmental corrosion, as well as physical degradation such as surface pitting and cracking.
Characteristics of Incoloy 800H Welded Tubes
• High temperatures are a possibility.
• Very high creep rupture strength.
• Excellent resistance to sulfur-containing chemicals.
• Industrial heaters Components and systems
• Petrochemical Production
• Pressure vessels and heat exchangers are examples of heat-treating equipment.
• Hydrocarbon cracking
Applications Of Incoloy 800H Welded Tubes
• Valves, fittings, and other components corroded by industrial furnaces operating at temperatures ranging from 1100 to 1800° F • Heat-treating systems
• Power station super-heaters and re-heaters
• High-pressure vessels
Alloy 800H Welded Tubes (also known as Incoloy N08800 Welded Pipes) are used in heat-treating equipment such as baskets, trays, and fixtures. These UNS N08810 Welded Tubes are used in chemical and petrochemical processing industries for heat exchangers and other nitric acid piping systems, particularly where resistance to chloride stress-corrosion cracking is required. They are used in power plants for super-heater and re-heater tubing.
Heat treating machinery, chemical and petrochemical processing, nuclear power plants, and the paper pulp industry all use Alloys 800H Welded Tubes in corrosive and high-temperature environments. Heat-treating facilities use baskets, trays, and fixtures made of Incoloy 800H Welded Tubes.
Incoloy is the best material for elevated temperature but less critical applications due to its higher ferrous content and lower cost. Advantageously, it can be manufactured using the same equipment and processes as stainless steel.
This alloy is also available in different grades, with an emphasis on resistance to aggressive corrosion, especially in aqueous environments. While a basic form of Incoloy 800H Welded Tube is sufficient for most applications, further alloying with strengthening components improves resistance to chemical and environmental corrosion, as well as physical deterioration such as surface pitting and cracking.
