Nominal figures given by Haynes International: Cr 23, Mo 16, Cu 1.6. THE DISTINGUISHING ELEMENT IS COPPER: C-276 and C-22 carry no copper but do carry tungsten; C-2000 carries no tungsten but does carry copper. Trade names: HASTELLOY C-2000 (Haynes International) \u00b7 Alloy C-2000 \/ Alloy 2000 (Virgamet, Elgiloy).<\/div>\n

\n
For what<\/div>\n
A Ni-Cr-Mo-Cu SOLID-SOLUTION alloy. IT IS NOT PRECIPITATION HARDENABLE; it cannot be hardened by heat treatment, strength is raised only by cold work and is removed again by solution annealing.<\/div>\n<\/div>\n

NO VERIFIED AMS SPECIFICATION COULD BE FOUND FOR N06200. No AMS number appears in the specification list of Haynes International, the alloy’s own producer either; that list consists of ASTM\/ASME, AWS and DIN numbers.<\/span><\/div>\n<\/div>\n
\n
Advantage<\/div>\n
Covering two classes of environment with one material. In the same Haynes International table, the CRITICAL CREVICE TEMPERATURE to ASTM G48 (acidified 6 wt% FeCl3, 72 hours) is 80 C for C-2000 and 55 C for C-276: 25 C in favour of C-2000 on crevice attack.<\/div>\n<\/div>\n
\n
Welding<\/div>\n
Welded by GTAW\/TIG, GMAW\/MIG and SMAW\/covered electrode. Filler metal: ERNiCrMo-17 (bare wire, AWS A5.14) and ENiCrMo-17 (covered electrode, AWS A5.11); on the European side SG-NiCr23Mo16Cu (2.4698) and EL-NiCr23Mo16Cu (2.4699). NO PREHEAT IS REQUIRED.<\/div>\n<\/div>\n
\n
Limits<\/div>\n
1) CODE TEMPERATURE CEILING 427 C: the ceiling for ASME Section VIII Div. 1, ASME B31.3 and ASME B16.5 is 427 C (800 F); the VdTUV ceiling is 450 C. THIS IS NOT A HIGH-TEMPERATURE ALLOY; it is not bought for creep service or furnace work.<\/div>\n<\/div>\n
