Material Notes:
General DescriptionCarlson Alloy C 800 is a nickel-iron-chromium alloy, combining high strength with excellent resistance to oxidation and carburization at elevated temperatures. This alloy resists sulfur attack, internal oxidation, scaling and corrosion in a wide variety of industrial atmospheres.The high chromium content of C 800 assures good resistance to oxidation, while the nickel content imparts a fair degree of resistance to stress corrosion cracking.Carlson Alloy C 800H is essentially the same alloy as C 800 except the carbon content is restricted to the upper portion of the specified range. C 800H also receives a solution-anneal which produces a coarser grain structure. This assures higher creep and rupture strengths, enabling C 800H to be used in applications that require prolonged exposure at elevated temperatures and/or in corrosive environments.ApplicationsChemical Processing – heat exchangers for nitric acid production; calciners, dryers and recuperators in soda ash plants; process equipment in fiberglass and ore processing plants.Petroleum and Petrochemical – tubing for hydrotreaters and effluent coolers; tubing, manifolds, pigtails and quench lines in hydrogen reformers; flare tips for incinerating waste gasses in refineries; reformer tubing, catalyst grid supports and converters for ammonia production; ethylene furnaces; tubing, bends and flanges for vinyl chloride production; steam superheaters for styrene production.Power Generation – boiler superheaters and reheater tubes and shields; gas turbine combustion cans, transition liners and diffusers.Thermal Processing – baskets and boxes, fixtures and radiant tubes for heat treat furnaces.Steel Production – coke plat quench-car liners and process piping; steam methane reformers and recuperators for direct reduction of iron ore.Information provided by Carlson
