Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Incoloy Alloy 20 Pipe Fittings, which is more stable in melts between 1000 Degree C and 1190 Degree C. In mixtures of nitric and hydrofluoric acids such as those used in pickling of stainless steels and reprocessing of nuclear fuel elements, Alloy 20 Compression Pipe Fittings has displayed excellent corrosion resistance. At boiling temperatures, Alloy 20 Compression Fittings is resistant to lower acid concentrations. Alloy 20 Accessories can be machined using conventional machining methods which are used for iron – based alloys. Machining operations of Alloy 20 Ferrule Fittings are performed using commercial coolants.
