Nickel Alloy Forging Discs Hastelloy C276 Pulp Paper Pharmaceutical Industry
Nickle Alloy disc, a thin, projecting metal stripattached to asemiconductor to dissipateheat. It is widely used incatering and kitchenware,elevators,chemical equipment,machinery manufacturing,architectural decoration, metaproducts, automobiles, pressurevessels and other felds.
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.
