Nickel Alloy Angle Bar Hastelloy C276 UNS N10276 For Bridge And Equipment
Nickle Alloy Angle Bar, or angle iron, is basically manufactured by hot-rolled high strength Nickle Alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree. Structural steel angles have lots of dimensions to comply with your uses. In addition, bespoke sizes are available. I
Many Uses:
Hastelloy C276 (UNS N10276) is a nickel-molybdenum alloy withuniversal corrosion resistance unmatched by any other alloy. C276 is also known as Inconel C276 or Hastelloy C276 and is an improved wrought version of alloy C inthat it usualy doesn't need to be solution heat-treatedafter welding and has vastly improved fabricability. Thisaloy is resistant to the formation of grain boundaryprecipitates, specifically in the weld-heat affected zone.This attribute makes it suitable for use in the as-welded condition. It has excellent resistance to both localizedcorrosion and oxidizing or reducing media. Because of itsversatility, it can be used where corrosive conditions are likely to occur or in multipurpose plants.It's native corrosion resistant properties extendto a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media(organic and inorganic),chlorine,formic and acetic acids, aceticanhydride,and seawater and brine solutions.
Applications
Some typical applications include equipment componentsin chemical and petrochemical organic chloride processesand processes utilizing halide or acid catalysts. therindustry applications are pulp and paper (digesters andbleach areas),scrubbers and ducting for flue gas desufurization,pharmaceutical, and food processingequipment. The sheet 0.044" thick in the heat-treatedcondition at 2050 °F,rapid quenched, has an averageolsen cup depth of 0.48".C-276 can be successfullyfabricated by many methods. The alloy tends to workarden but with the proper care, the alloy is readily hotand cold formed. Digesters and bleach plants in the paper industry. Components exposed to sour gas.Equipment for flue-gas desulphurisation plants. Evaporators, heat exchangers, filters and mixers used in sulphuric acid enyironments. Sulphuric acid reactors. Organic chloride process equipment. Equipment for processes utilising halide or acid catalysts.
Machining:
Nickel based alloys can be difficult tomachinine.However, it should be emphasized that thesealloys can be machined using conventional productionmethods at satisfactory rates. These alloys harden rapidlygenerate high heat during cutting, weld to the cuttingtool surface and offer high resistance to metal removabecause of their high shear strengths. The following arekey points which should be considered during machining operations: capacity/tools/positive cut/lubrication.
