Alloy C nickel alloy plate also has good high temperature strength and moderate oxidation resistance although the alloy will eventually form embrittling high temperature precipitates. The alloy tends to work harden but with the proper care, the alloy is readily hot and cold formed. An in-process anneal may be necessary with a high degree of cold working. Since Alloy C nickel alloy plate is prone to work—hardening, only low cutting speeds should be used and the cutting tool should be engaged at all times. The combination of the high molybdenum and chromium content, along with the addition of tungsten, make Alloy C nickel alloy plate highly resistant to chloride stress corrosion cracking, pitting, crevice corrosion and general corrosion. It also performs well in seawater, especially under crevice conditions where other frequently used alloys such as stainless steel, Alloy and Alloy fail. Alloy C nickel alloy plate is used extensively in the recovery and processing of sour natural gas which contains hydrogen sulfide along with carbon dioxide and chlorides.

Other industry applications are pulp and paper digesters and bleach areasscrubbers and ducting for flue gas desulfurization, pharmaceutical and food processing equipment.
The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat affected zones of welding c27. The combination of the high molybdenum and chromium content, along with the addition of tungsten, make Alloy C nickel alloy plate highly resistant to chloride stress corrosion cracking, pitting, crevice corrosion and general corrosion.
Fabrication with Hastelloy C Dry or water-base coolant. Reaming C-2 or C-3 grade: This alloy has excellent resistance to pitting and stress corrosion cracking.
Water-base coolant may cause chipping and rapid failure of carbide tools in interrupted cuts.
Turning or Facing C-2 and C-3 grade: Same as high speed steel. Dry2, oil3, or water-base coolant4. The web must thinned to reduce thrust.
Tipped reamers recommended, solid f276 reamers require vary good setup. Although there are several variations of the Hastelloy nickel alloy, Hastelloy C is by far the most widely used. Cold Forming Alloy C nickel alloy plate should be in the annealed condition for cold working. Carbide not generally successful, C- grade may work. The operating conditions of flue gas desulfurization systems offer a challenging environment for corrosion resistant materials.

cc276 C-2 grade not recommended, but tipped drills may be successful on rigid setup if no great depth. Alloy C nickel alloy plate is one of the premier corrosion resistant materials that performs exceptionally well in both oxidizing and reducing environments. A viscosity at degrees F from 50 to SSU. Alloy C nickel alloy plate is highly resistant to concentrated solutions of oxidizing salts including iron and copper chloride. Physical Properties Density 0. Brushing with a stainless steel wire brush after welding will remove the heat tint and produce a surface area that does not require additional pickling.

HASTELLOY C276 (UNS N10276)
Use positive axial and radial rake, 45 degree corner angle, 10 degree relief angle. C-2 or C-3 grade: Fabrication Data Alloy C nickel alloy plate can be easily welded and processed utilizing standard shop fabrication practices for austenitic stainless steels and nickel based alloys. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.
General plasma cutting recommendations are presented in Table Shop air or any oxygen bearing gases should be avoided when plasma cutting these alloys. Applications Air 2c76 Control — flue gas desulfurization systems — stack liners, absorbers, ducts, dampers, stack gas re-heaters and fans Chemical Processing — heat exchangers, pressure vessels, tanks, evaporators, piping, flanges and fittings, pumps and valves Oil and Gas Production — sour gas service components Pharmaceutical Production — reactor vessels, piping, flanges and fittings, pumps and valves Pulp and Paper — bleaching vessels and digesters Waste Treatment — incinerators for toxic, industrial and municipal waste Ore Processing.
Coolant-feed carbide tipped drills may be economical in some setups. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing c27.
Negative rake angle tools can be considered for intermittent cuts and heavy stock removal.
