AISI / SAE · United States · 8 grades # 1042 The designation 1042 is carried by 8 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **8** - [*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 8 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% | S% | P% | Cr% | Mn% | Ni% | |---|---|---|---|---|---|---|---|---|---| | [1.0503](/materials/material-no/1.0503 "1.0503") | [1.0503](/materials/material-no/1.0503 "1.0503") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 93 | 0,42-0,50 | 0,045 | 0,045 | ≤0,40 | 0,50-0,80 | ≤0,40 | | [1.0511](/materials/material-no/1.0511 "1.0511") | [1.0511](/materials/material-no/1.0511 "1.0511") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 63 | 0,37-0,44 | 0,045 | 0,045 | ≤0,40 | 0,50-0,80 | ≤0,40 | | [C42D](/materials/din-en/c42d "C42D") | [1.0541](/materials/material-no/1.0541 "1.0541") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 5 | 0,40-045 | 0,03 | 0,03 | ≤0,20 | 0,50-0,80 | ≤0,25 | | [C42D2](/materials/din-en/c42d2 "C42D2") | [1.1154](/materials/material-no/1.1154 "1.1154") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 5 | 0,40-0,44 | 0,025 | 0,02 | ≤0,10 | 0,50-0,70 | ≤0,10 | | [C46D2](/materials/din-en/c46d2 "C46D2") | [1.1162](/materials/material-no/1.1162 "1.1162") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 3 | 0,44-0,48 | 0,025 | 0,02 | ≤0,10 | 0,50-0,70 | ≤0,10 | | [1.1191](/materials/material-no/1.1191 "1.1191") | [1.1191](/materials/material-no/1.1191 "1.1191") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 39 | 0,42-0,50 | 0,035 | 0,03 | ≤0,40 | 0,50-0,80 | ≤0,40 | | [1.1191](/materials/material-no/1.1191 "1.1191") | [1.1191](/materials/material-no/1.1191 "1.1191") 1.1 | [Others](/categories/others "Others") | 32 | 0,42-0,50 | 0,03 | 0,035 | — | 0,50-0,80 | — | | [SAE 1042](/materials/din-en/sae-1042 "SAE 1042") | [1.9503](/materials/material-no/1.9503 "1.9503") 1.9 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 3 | 0,40-0,47 | 0,05 | 0,03 | — | 0,60-0,90 | — | ## Not sure which one your print means?
