This name is carried by several grades. The elements shown are the ones whose values actually differ across the set — the ones that decide the question. Values are the source text verbatim; an em dash means no value on file for that element on that grade, not zero. | Grade | Material no. | Category | Designations | Fe% | Ni% | Cr% | C% | Mo% | Cu% | |---|---|---|---|---|---|---|---|---|---| | [Ni 99,6](/materials/din-en/ni-99-6 "Ni 99,6") | [2.4060](/materials/material-no/2.4060 "2.4060") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 17 | ≤0,25 | ≥99,6 | — | ≤0,08 | — | ≤0,15 | | [Ni 99,2](/materials/din-en/ni-99-2 "Ni 99,2") | [2.4066](/materials/material-no/2.4066 "2.4066") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 43 | ≤0,40 | ≥99,2 | — | ≤0,10 | — | ≤0,25 | | [NiCr21Mo14W](/materials/din-en/nicr21mo14w "NiCr21Mo14W") | [2.4602](/materials/material-no/2.4602 "2.4602") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 19 | 2,00-6,00 | Rest/Bal. | 20,0-22,5 | ≤0,010 | 12,5-14,5 | — | | [NiCr30FeMo](/materials/din-en/nicr30femo "NiCr30FeMo") | [2.4603](/materials/material-no/2.4603 "2.4603") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 16 | 13,0-17,0 | Rest/Bal. | 28,0-31,5 | ≤0,03 | 4,00-6,00 | 1,00-2,40 | | [SG-NiCr21Fe18Mo](/materials/din-en/sg-nicr21fe18mo "SG-NiCr21Fe18Mo") | [2.4613](/materials/material-no/2.4613 "2.4613") 2.4 | [Others](/categories/others "Others") | 16 | 17,0-20,0 | Rest/Bal. | 20,0-23,0 | ≤0,10 | 8,00-10,0 | — | | [NiMo28](/materials/din-en/nimo28 "NiMo28") | [2.4617](/materials/material-no/2.4617 "2.4617") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 16 | ≤2,00 | Rest/Bal. | ≤1,00 | ≤0,010 | 26,0-30,0 | ≤0,50 | | [NiCr20CuMo](/materials/din-en/nicr20cumo "NiCr20CuMo") | [2.4660](/materials/material-no/2.4660 "2.4660") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 15 | Rest/Bal. | 32,0-38,0 | 19,0-21,0 | ≤0,07 | 2,00-3,00 | 3,00-4,00 | | [NiCr22Fe18Mo](/materials/din-en/nicr22fe18mo "NiCr22Fe18Mo") | [2.4665](/materials/material-no/2.4665 "2.4665") 2.4 | [High-temperature steels](/categories/high-temperature-steels "High-temperature steels") | 26 | 17,0-20,0 | Rest/Bal. | 20,5-23,0 | 0,05-0,15 | 8,00-10,0 | ≤0,50 | | [NiCr15Fe](/materials/din-en/nicr15fe "NiCr15Fe") | [2.4816](/materials/material-no/2.4816 "2.4816") 2.4 | [High-temperature steels](/categories/high-temperature-steels "High-temperature steels") | 20 | 6,00-10,0 | ≥72,0 | 14,0-17,0 | 0,05-0,10 | — | ≤0,50 | | [NiMo16Cr15W](/materials/din-en/nimo16cr15w "NiMo16Cr15W") | [2.4819](/materials/material-no/2.4819 "2.4819") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 13 | 4,00-7,00 | Rest/Bal. | 14,5-16,5 | ≤0,010 | 15,0-17,0 | ≤0,50 | | [NiCr23Fe](/materials/din-en/nicr23fe "NiCr23Fe") | [2.4851](/materials/material-no/2.4851 "2.4851") 2.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 21 | ≤18,0 | 58,0-63,0 | 21,0-25,0 | 0,03-0,10 | — | ≤0,50 | | [NiCr22Mo9Nb](/materials/din-en/nicr22mo9nb "NiCr22Mo9Nb") | [2.4856](/materials/material-no/2.4856 "2.4856") 2.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 24 | ≤5,00 | ≥58,0 | 20,0-23,0 | 0,03-0,10 | 8,00-10,0 | ≤0,50 | | [NiCr21Mo](/materials/din-en/nicr21mo "NiCr21Mo") | [2.4858](/materials/material-no/2.4858 "2.4858") 2.4 | [Nickel and cobalt alloys](/categories/nickel-and-cobalt-alloys "Nickel and cobalt alloys") | 18 | Rest/Bal. | 38,0-46,0 | 19,5-23,5 | ≤0,025 | 2,50-3,50 | 1,50-3,00 | | [NiCr22Fe18Mo](/materials/din-en/nicr22fe18mo "NiCr22Fe18Mo") | [Ni 6002](/materials/material-no/ni-6002 "Ni 6002") | [Others](/categories/others "Others") | 16 | 17,0-20,0 | ≥45,0 | 20,0-23,0 | 0,05-0,15 | 8,00-10,0 | ≤0,50 | | [NiCr21Fe18Mo9](/materials/din-en/nicr21fe18mo9 "NiCr21Fe18Mo9") | [Ni 6002](/materials/material-no/ni-6002 "Ni 6002") | [Others](/categories/others "Others") | 16 | 17,0-20,0 | ≥44,0 | 20,5-23,0 | 0,05-0,15 | 8,00-10,0 | ≤0,50 | ## Not sure which one your print means?
