\n
Nickel 201<\/div>\n
UNS N02201 \u00b7 W.Nr. 2.4068 (Special Metals and VDM also list 2.4061 for the same alloy) \u00b7 EN\/DIN designation LC-Ni99 (low-carbon nickel); producer designation Nickel LC 99.2 \u00b7 Ni(+Co) 99.0% min \u2013 C 0.02% max \u2013 Cu 0.25% max \u2013 Fe 0.40% max \u2013 Mn 0.35% max \u2013 Si 0.35% max \u2013 S 0.010% max (ASTM B160 and ASTM B162 Table 1). It is commercially pure nickel; no strengthening alloying element is added. The ONLY compositional difference from Nickel 200 is the carbon ceiling.<\/div>\n
\n
Not to be confused with<\/div>\n

Nickel 200<\/a><\/div>\n<\/div>\n

\n
\n
For what<\/div>\n
The low-carbon version of commercially pure nickel. It is NOT PRECIPITATION HARDENABLE; it takes its strength from cold work only and cannot be hardened by ageing. Because the carbon ceiling is lowered to 0.02%, graphite does not precipitate at the grain boundaries above 315 \u00b0C;<\/div>\n<\/div>\n
\n
Forms<\/div>\n
Round bar \u00b7 flat bar \u00b7 plate \u00b7 sheet \u00b7 strip \u00b7 tube and pipe (seamless and welded) \u00b7 wire \u00b7 forging. All forms are supplied to order.<\/div>\n<\/div>\n
\n
Standards<\/div>\n
AMS 5553<\/b> \u2014 sheet and strip; the SAE title is ‘Nickel, Sheet and Strip Low (0.02 max) Carbon Annealed’. Because the carbon ceiling is 0.02%, this specification belongs to Nickel 201. \u00b7 ASTM B160 \/ ASME SB-160 \u2014 rod and bar. \u00b7 ASTM B161 \/ ASME SB-161 \u2014 seamless pipe and tube. \u00b7 ASTM B162 \/ ASME SB-162 \u2014 plate, sheet and strip. \u00b7 ASTM B163 \/ ASME SB-163 \u2014 condenser and heat-exchanger tube. \u00b7 ASTM B725 \/ ASME SB-725 \u2014 welded pipe. \u00b7 ASTM B730 \/ ASME SB-730 \u2014 welded tube. \u00b7 ASTM B751, B775, B829 \u2014 general requirements for tubular products. \u00b7 ASTM B366 \/ ASME SB-366 \u2014 welded fittings. \u00b7 DIN 17740, 17750, 17751, 17752, 17753, 17754 \u00b7 ISO 6207, 6208, 9723, 9724, 9725 \u00b7 BS 3072, 3073, 3074, 3076 (NA12) \u00b7 VdTUV 345.
ASTM B564 TRAP: the scope list of ASTM B564 (nickel alloy forgings) DOES include N02200 but DOES NOT include N02201. Many sales pages list Nickel 201 forgings under B564; that is wrong.<\/span><\/div>\n<\/div>\n
\n
Advantage<\/div>\n
Lowering the carbon ceiling from 0.15% to 0.02% removes graphite precipitation at the grain boundaries above 315 \u00b0C and the embrittlement that follows from it.<\/div>\n<\/div>\n
\n
Welding<\/div>\n
Filler metal: Special Metals Nickel Filler Metal 61 (gas tungsten arc and gas metal arc) and Nickel Welding Electrode 141 (shielded metal arc) \u2014 the same consumables as Nickel 200. The oxyacetylene process is NOT applicable to Nickel 201 (Special Metals). Preheat is not normally required;<\/div>\n<\/div>\n
\n
Limits<\/div>\n
NOT PRECIPITATION HARDENABLE: there is no solution treatment plus ageing step (nothing like H900 or H1025); strength rises only with cold work. \u00b7 SPECIFICATION MINIMUMS ARE LOWER THAN NICKEL 200: in ASTM B162, annealed plate, sheet and strip requires 345 MPa tensile and 80 MPa yield for N02201 against 380 MPa and 100 MPa for N02200.<\/div>\n<\/div>\n
