AISI / SAE · United States · 6 grades # 1025 The designation 1025 is carried by 6 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **6** - [*Category* **Quenched and tempered steels · 133 grades**](/categories/quenched-and-tempered-steels "Category: Quenched and tempered steels · 133 grades") [Search](/search "Steel grade search")[Inquiry](/inquiry "Inquiry") ## Which of the 6 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 | S% | P% | Mn% | C% | Cr% | Ni% | |---|---|---|---|---|---|---|---|---|---| | [C25](/materials/din-en/c25 "C25") | [1.0406](/materials/material-no/1.0406 "1.0406") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 58 | 0,045 | 0,045 | 0,40-0,70 | 0,22-0,29 | ≤0,40 | ≤0,40 | | [C26D](/materials/din-en/c26d "C26D") | [1.0415](/materials/material-no/1.0415 "1.0415") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 8 | 0,03 | 0,03 | 0,50-0,80 | 0,24-0,29 | ≤0,20 | ≤0,25 | | [C26D2](/materials/din-en/c26d2 "C26D2") | [1.1139](/materials/material-no/1.1139 "1.1139") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 7 | 0,025 | 0,02 | 0,50-0,70 | 0,24-0,29 | ≤0,10 | ≤0,10 | | [1.1158](/materials/material-no/1.1158 "1.1158") | [1.1158](/materials/material-no/1.1158 "1.1158") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 19 | 0,035 | 0,035 | 0,40-0,70 | 0,22-0,29 | ≤0,40 | ≤0,40 | | [C25R](/materials/din-en/c25r "C25R") | [1.1163](/materials/material-no/1.1163 "1.1163") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 8 | 0,020-0,040 | 0,035 | 0,40-0,70 | 0,22-0,29 | ≤0,40 | ≤0,40 | | [SAE 1025](/materials/din-en/sae-1025 "SAE 1025") | [1.9415](/materials/material-no/1.9415 "1.9415") 1.9 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 7 | 0,05 | 0,03 | 0,30-0,60 | 0,22-0,28 | — | — | ## Not sure which one your print means?
