Spot Goods Nr. 1.4958 Alloy Tube For Heat Treatment Equipment Incoloy 800ht Pipe

Incoloy 800HT (UNS N08811 / W.Nr. 1.4959) nickel-iron-chromium alloys that have the same basic composition as INCOLOY alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum and titanium contents in conjunction with a high temperature anneal. Used in chemical and petrochemical processing, power plants for super-heater and reheater tubing, industrial furnaces and heat-treating equipment.

Product Introduction

Features

▪ Resistance to prolonged exposure to elevated temperatures
▪ Excellent resistance to oxidation, sulfidation, and carburization
▪ Added Carbon and annealing treatment allows for higher creep and rupture properties above 600ºC
▪ Resistant to high temperature corrosion
▪ Readily machined by standard methods
▪ Best joined/welded using products for high temperature situations
▪ Resistance to aqueous corrosion at moderate temperatures

Incoloy 800ht Application

▪ Chemical and Petrochemical Processing-process equipment for the production of ethylene, ethylene dichloride, acetic anhydride, ketene and oxy-alcohol
▪ Petroleum Refining-steam/hydrocarbon reformers and hydrodealkylation units
▪ Power Generation-steam super-heaters and high temperature heat exchangers in gas-cooled nuclear reactors, heat exchangers and piping systems in coal-fired power plants
▪ Thermal Processing Fixtures-radiant tubes, muffles, retorts and fixtures for heat-treating furnaces

Incoloy 800ht Key Features:

Corrosion Resistance: The addition of nickel & chromium to 800HT ensures excellent carburization, oxidation, & sulfidation.

Organic Media Resistance: This alloy also flaunts great resistance to widely found organic media components such as acetic, formic, as well as propionic acids.

High Heat Fabrication: Alloy 800HT is known to fabricate easily in high heat between 1200°F & 1600°F. However, anything below this leads to improper fabrication.

High Resistance to Creep Rupture: Incoloy 800HT has better creep-rupture resistance strength as compared to Alloy 800 given the close control for Al, Ti, & C.
