C2000 flanges have better temperature capabilities in hydrofluoric, sulfuric, and diluted hydrochloric acids due to the addition of copper.

The material is resistant to chlorides and acids so that the primary uses are in the acid processing, chemical, sea water and marine applications.

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid.

Hastelloy X alloy (UNS N06002; W.Nr. 2.4665) is a high temperature, matrix strengthened, NiCrFeMo alloy with excellent oxidation resistance and excellent Strength. Hastelloy X alloy is a nickel-chromium-iron-molybdenum alloy that provides excellent oxidation resistance and high temperature strength while still being easy to manufacture.

According to the flange size, wall thickness and diameters, the pressure classes vary from class 150 through class 2500. There are also different faced flanges such as the ring type joint Alloy B2 RTJ Flange, raised face flange and flat face flange.

Alloy B2 should not be used at temperatures between 1000¡ãF and 1600¡ãF as the alloy forms secondary phases that could decrease the ductility of the material.

UNS N10276 Sheets has excellent resistance to pitting corrosion, pressure corrosion cracking and a far higher resistance to crevice corrosion than steels of alloy.

Alloy C276 is a Ni-Cr-Mo alloy containing W and very low carbon and Si content.

The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Hastelloy G30 Hastelloy alloys exhibit better resistance to commercial phosphoric acid than other nickel or iron based alloys. Its application as an acid evaporator in the fertilizer industry is increasing day by day.
