GOST · Russia / CIS · 7 grades # 40KHN2MА The designation 40KHN2MА is carried by 7 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **7** - [*Category* **Quenched and tempered steels · 133 grades**](/categories/quenched-and-tempered-steels "Category: Quenched and tempered steels · 133 grades") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") [Search](/search "Steel grade search")[Inquiry](/inquiry "Inquiry") ## Which of the 7 do you want? 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 | C% | Cr% | Ni% | Mo% | Si% | P% | |---|---|---|---|---|---|---|---|---|---| | [1.6511](/materials/material-no/1.6511 "1.6511") | [1.6511](/materials/material-no/1.6511 "1.6511") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 91 | 0,32-0,40 | 0,90-1,20 | 0,90-1,20 | 0,15-,30 | ≤0,40 | 0,035 | | [1.6511](/materials/material-no/1.6511 "1.6511") | [1.6511](/materials/material-no/1.6511 "1.6511") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 91 | 0,32-0,40 | 0,90-1,20 | 0,90-1,20 | 0,15-,30 | ≤0,40 | 0,035 | | [1.6511](/materials/material-no/1.6511 "1.6511") | [1.6511](/materials/material-no/1.6511 "1.6511") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 91 | 0,32-0,40 | 0,90-1,20 | 0,90-1,20 | 0,15-,30 | ≤0,40 | 0,035 | | [40 NiCrMo 8 4](/materials/din-en/40nicrmo8-4 "40 NiCrMo 8 4") | [1.6562](/materials/material-no/1.6562 "1.6562") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 33 | 0,37-0,44 | 0,70-0,95 | 1,65-2,00 | 0,30-0,40 | 0,20-0,35 | 0,02 | | [40NiCrMo6](/materials/din-en/40nicrmo6 "40NiCrMo6") | [1.6565](/materials/material-no/1.6565 "1.6565") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 56 | 0,35-0,45 | 0,90-1,40 | 1,40-1,70 | 0,20-0,30 | 0,15-0,35 | 0,035 | | [1.6582](/materials/material-no/1.6582 "1.6582") | [1.6582](/materials/material-no/1.6582 "1.6582") 1.6 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 84 | 0,30-0,38 | 1,30-1,70 | 1,30-1,70 | 0,15-0,30 | ≤0,40 | 0,025 | | [40NiMoCr10-5](/materials/din-en/40nimocr10-5 "40NiMoCr10-5") | [1.6745](/materials/material-no/1.6745 "1.6745") 1.6 | [Others](/categories/others "Others") | 7 | 0,37-0,43 | 0,60-0,80 | 2,40-2,70 | 0,40-0,60 | 0,15-0,35 | 0,035 | ## Not sure which one your print means?
