C-276 Stainless Steel Plate General Properties:

Alloy C276 nickel alloy plate (UNS N10276) is an austenitic nickel-molybdenum-chromium alloy with a small addition of tungsten. It is one of the premier corrosion resistant materials available for process industries. Alloy C276 nickel alloy plate has excellent corrosion resistance in both oxidizing and reducing environments.

The combination of the high molybdenum and chromium content, along with the addition of tungsten, make Alloy C276 nickel alloy plate highly resistant to chloride stress corrosion cracking, pitting, crevice corrosion and general corrosion.

Alloy C276 nickel alloy plate can operate in oxidizing atmospheres up to 1900oF (1038oC), however, the alloy lacks sufficient chromium content to operate successfully in the most strongly oxidizing environments like hot, concentrated nitric acid.

The low carbon content of Alloy C276 nickel alloy plate enables the alloy to be utilized in the as-welded condition. It cannot be hardened by heat treatment, but can be hardened by cold working. The alloy has a higher work-hardening rate than the austenitic stainless steels which should be taken into consideration.

Alloy C276 nickel alloy plate can be easily welded and processed utilizing standard shop fabrication practices for austenitic stainless steels and nickel based alloys.

C-276 Stainless Steel Plate Fabrication Data:

Alloy C276 nickel alloy plate can be easily welded and processed utilizing standard shop fabrication practices for austenitic stainless steels and nickel based alloys.

Hot Forming

The hot-working temperature range for Alloy C276 nickel alloy plate is 1600 – 2250°F (870 – 1230°C). The alloy should be water quenched after hot working. Heat treatment is recommended after hot working to ensure maximum corrosion resistance.

Cold Forming

Alloy C276 nickel alloy plate should be in the annealed condition for cold working. The alloy has a higher work-hardening rate than the austenitic stainless steels which should be taken into consideration. An in-process anneal may be necessary with a high degree of cold working. If the alloy undergoes greater than 15% deformation during cold working, a solution anneal may be necessary.

Welding

Alloy C276 nickel alloy plate can be readily welded by most standard processes including GTAW (TIG), PLASMA, GMAW (MIG/MAG) and SMAW (MMA). A post weld heat treatment is not necessary. 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.

Machining

Alloy C276 nickel alloy plate should preferably be machined in the annealed condition. Since Alloy C276 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. Adequate cut depth is necessary to assure avoiding contact with the previously formed work-hardened zone.
