HASTELLOY® C-2000® ALLOYHASTELLOY C-2000 alloy, developed to optimize a material for broad applicability,began with the conceptual idea of adding copper to the well established nickel-chromium-molybdenum (Ni-Cr-Mo) family of alloys. Since its introduction in late1995, it has gained, and continues to gain, dramatic market acceptance owing to its inherent versatility. This technical innovation not only offers increased resistance to aqueous corrosion but has succeeded in expanding the overall applicability for Ni-Cr-Mo family of alloys.

This new material was designed to resist an extensive range of corrosive chemicals, including sulfuric, hydrochloric, and hydrofluoric acids. Unlike previous Ni-Cr-Moalloys, which were optimized for use in either oxidizing or reducing acids, C-2000 alloyextends corrosion resistance in both types of environments. The combination ofmolybdenum and copper (at levels of 16 and 1.6 wt. %, respectively) provide the outstanding resistance to reducing media, while oxidizing acid resistance is providedby a high chromium content (23 wt. %).

From an engineering viewpoint, C-2000 alloy offers significant potential toward production improvement in plant operations. When used in place of the established Ni-Cr-Mo alloys, the enhanced resistance to corrosion in certain media results in longerequipment life (for a given thickness of material), while providing a greater degree ofsafety during an upset condition. This increase in corrosion performance versatilitysupports the industry trend toward multiple uses of equipment (reactors, heat exchangers, valves, pumps, etc.) to gain a greater return on the capitalized expense.For example, a reactor could be handling a hydrochloric acid-based product mixture,then used in another operation which may rely on the use of a nitric acid-basedprocess. Because of its versatility, C-2000 alloy is the best equipped nickel-based alloyto handle this degree of variance in process streams.

HASTELLOY C-2000® alloy brings a new dimension to the well known versatility of Ni-Cr-Mo alloys inresisting corrosion under widely varying conditions, combining outstanding resistance to oxidizing mediawith superior resistance to reducing environments. C-2000 alloy represents a true performance breakthrough for chemical process equipment applications.

Previously, attempts to fully optimize the corrosion resistance of Ni-Cr-Mo alloys have been only partlysuccessful. A high chromium content is required for resistance to oxidizing media, such as when ferricions, cupric ions or dissolved oxygen are present. Reducing environments, however, such as dilutehydrochloric or sulfuric acids, require a high content of molybdenum plus tungsten. Metallurgical stabilitylimitations dictate that you cannot optimize both.

HASTELLOY C-2000 alloy solves this alloy design dilemma. A high chromium content is combined withboth molybdenum and copper contents, sufficient to provide outstanding resistance to reducing environments, with no sacrifice in metallurgical stability.

C-2000 alloy also exhibits pitting resistance and crevice corrosion resistance superior to the industry standard, C-276 alloy. Its forming, welding and machining characteristics are similar to C-276 alloy.

C-2000 alloy is available in most common product forms: plate, sheet, billet, bar, wire, covered electrodes, pipe and tubing. Wrought forms of this alloy are furnished in the solution heat-treated condition unless otherwise specified.

HASTELLOY C-2000 alloy is covered by ASME Section VIII, Division I under Code Case No. 2240, and byASTM specifications B-564, B-574, B-575, B-619, B-622, B-626 and B-366. The DIN specifications are17744 No. 2.4675 (all forms) and NiCr23Mo16Cu (all forms). C-2000 alloy falls within the range of UNSnumber N06200 but has a more restricted composition for improved performance. These improvementsare of such significance that it has been widely patented throughout the world.

Haynes Welding Guidelines 2/7/01 8:06 AM Page 1



• Safe working conditions should be established prior to welding. Welders should be properly protected, confined spaces should be avoided, and adequate ventilation should be provided. The recommendations of ANSI/ASC Z49.1-88, “Safety in Welding and Cutting”, should be followed.

• Surfaces to be welded, and adjacent areas, should be cleaned and degreased thoroughly prior to welding.

• The Ni-Cr-Mo alloys exhibit low penetration characteristics, therefore adequate joint access (weld angle) and minimal land are suggested.

• The interpass temperature should be held below 93˚C (200˚F), and excessive heating should be avoided (especially on thin parts).

• The weld metal is viscous (sluggish), and therefore some torch manipulation is usually necessary; increasing the current (amperage) will not substantially increase the fluidity of the weld puddle.

• Oxy-acetylene and submerged-arc welding are not recommended.

• Covered electrodes from a new (unopened) can require no drying; however, unused electrodes should bestored in an oven held in the temperature range of 121˚C (250˚F) to 204˚C (400˚F).

• A backing gas of 100% argon should be used for the root pass during gas-tungsten arc or gas-metal arc welding; for shielded-metal arc welding, grinding of the back side of the root pass is necessary.

• For gas-tungsten arc welding, a constant-current power supply, equipped with a high frequency start and downslope control, is recommended; torches with gas diffuser lenses provide the optimum gas coverage.

• Post-weld stress relieving, at approximately 650˚C (1202˚F) is inappropriate for the Ni-Cr-Mo alloys; normally a post-weld heat treatment is not necessary, but, if stresses must be relieved, a full solution anneal at 1149˚C (2100˚F) is recommended, followed by water quenching.

• If more than 1% of an oxidizing shielding gas is used during gas-metal arc welding, then grinding of the weld bead between each pass is recommended.

• Water-cooled torches are recommended for gas-metal arc spray transfer and synergic transfer (above 120A).
