Tubi di Incoloy 800 Tubi in lega 800 ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 EN 10216-5 1.4558 Seamless Tubing. Incoloy 800 Tubes designed to resist Oxidation and Carburization. The general corrosion resistance is excellent. Incoloy alloy 800 is a widely used material of construction for equipment that must have high strength and oxidation resistance, carburization, and other harmful effects of alta temperatura exposure. (For high temperature applications requiring optimum creep and rupture properties, Incoloy alloys 800H and 800HT are used).

ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 Seamless Tubing is particularly useful for ad alta temperatura equipment in the petrochemical industry because the alloy doesn’t form the embrittling sigma phase after long time exposure at 1200°F (649°C). Excellent resistance to chloride stress-corrosion cracking is another important feature of alloy 800. Alloy 800H is a solution trattato termicamente (2100°F/1150°C), controlled-carbon version of alloy 800 with improved elevated temperatura proprietà. It has improved creep and stress-rupture characteristics in the 1100°F (593°C) to 1800°F (982°C) temperature range.

A Ni-Cr-Fe alloy that resists high temperature oxidation. This alloy is a first choice for an upgrade from the 300 series stainless steel when improved performance or strength at temperatura is required. For higher ASME Boiler and Pressione Code design values, consider Alloy 800HT.

ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 Seamless Tubing Applications

ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 Seamless Tubing is used in a variety of applications involving exposure to corrosive environments and high temperatures. It is used for trattamento termico equipment such as baskets, trays and fixtures. In chemical and petrochemical processing the alloy is used for scambiatore di calore and other piping systems in acido nitrico media especially where resistance to fessurazione da stress-corrosione da cloruro is required. In nuclear power plants, it is used for steam-generator tubing. The alloy is often used in domestic appliances for sheathing of electric heating elements. In the production of paper pulp, digester liquid heaters are often made of alloy 800. In petroleum processing , the alloy is used for heat exchanger that air-cool the process stream.

Typical applications for alloy 800 and 800H are – Heat exchangers and process piping,

• carburizing fixtures and retorts; furnace components,
• electric range heating-element sheathing
• extruded tubing for ethylene and steam methane reforming furnaces
• ammoniaca effluent coolers.
• Radiant syngas coolers in IGCC gasification.
• Chemical and petrochemical processing equipments
• Power generation
• Tubi per surriscaldatori e tubi per surriscaldatori in acciaio inox
• Thermal procession fixtures
• Steel production.

Incoloy 800 Tubing Corrosion Resistance

The chromium in the alloy imparts resistance to oxidation and corrosione. The high percentage of nickel maintains an austenitico structure so that the alloy is ductile. the nickel content also contributes resistance to scaling, general corrosion, and fessurazione da stress-corrosione. The iron content provides resistance to internal ossidazione. Neither Alloy 800 nor Alloy 304 are suggested for acido solforico service except at lower concentrations and temperatures. UNS N08800 is highly resistant, although not totally immune, to stress corrosion cracking.

Incoloy 800 Tubes Oxidation Resistance

The alloys are particularly well suited for high temperature applications such as furnace parts and related heating equipment, for petrochemical reforming units and isocracker tubs, and for handling superheated stem in unclear and conventional power plants. With the specified high levels of chromium and nickel, the alloys offer superior resistance to oxidation and scaling, and to carburization as well.

Incoloy 800 Tubes Cold Working

La formatura a freddo può essere eseguita con utensili standard, anche se gli acciai da utensili a basso tenore di carbonio non sono raccomandati per la formatura in quanto tendono a produrre gallerie. I materiali morbidi per stampi (bronzo, leghe di zinco, ecc.) riducono al minimo la formazione di galla e producono buone finiture, ma la durata degli stampi è piuttosto breve. Per le lunghe produzioni, gli acciai legati per utensili (D-2, D-3) e gli acciai ad alta velocità (T-1, M-2, M-10) danno buoni risultati, soprattutto se cromati duramente per ridurre la formazione di galla. L'utensileria deve essere tale da consentire giochi e raggi liberi. Per ridurre al minimo la formazione di galla in tutte le operazioni di formatura si devono usare lubrificanti per impieghi gravosi. La piegatura di lamiere o lastre a 180 gradi è generalmente limitata a un raggio di curvatura di 1 T per materiali di spessore fino a 1/8″ e di 2 T per materiali di spessore superiore a 1/8″.

Incoloy 800 Seamless Tubing Annealing

Annealing after cold work hardening may be required. If so anneal at 1800 F for 15 minutes at temperature and air cool. Do not heat above 1800 F or grain growth will occur with degradation of strength.
