AISI / SAE · United States · 9 grades # 1050 The designation 1050 is carried by 9 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **9** - [*Category* **Quenched and tempered steels · 133 grades**](/categories/quenched-and-tempered-steels "Category: Quenched and tempered steels · 133 grades") - [*Category* **Steels for surface hardening · 13 grades**](/categories/steels-for-surface-hardening "Category: Steels for surface hardening · 13 grades") [Search](/search "Steel grade search")[Inquiry](/inquiry "Inquiry") ## Which of the 9 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% | Si% | Mn% | Cr% | |---|---|---|---|---|---|---|---|---|---| | [1.0535](/materials/material-no/1.0535 "1.0535") | [1.0535](/materials/material-no/1.0535 "1.0535") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 101 | 0,52-0,60 | 0,045 | 0,045 | ≤0,40 | 0,60-0,90 | ≤0,40 | | [C50](/materials/din-en/c50 "C50") | [1.0540](/materials/material-no/1.0540 "1.0540") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 25 | 0,47-0,55 | 0,045 | 0,045 | ≤0,40 | 0,60-0,90 | ≤0,40 | | [C50D](/materials/din-en/c50d "C50D") | [1.0586](/materials/material-no/1.0586 "1.0586") 1.0 | [Steels for surface hardening](/categories/steels-for-surface-hardening "Steels for surface hardening") | 8 | 0,48-0,53 | 0,03 | 0,03 | 0,10-0,30 | 0,50-0,80 | ≤0,15 | | [1.0601](/materials/material-no/1.0601 "1.0601") | [1.0601](/materials/material-no/1.0601 "1.0601") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 92 | 0,57-0,65 | 0,045 | 0,045 | ≤0,40 | 0,60-0,90 | ≤0,40 | | [C50E](/materials/din-en/c50e "C50E") | [1.1206](/materials/material-no/1.1206 "1.1206") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 33 | 0,47-0,55 | 0,035 | 0,03 | ≤0,40 | 0,60-0,90 | ≤0,40 | | [C53E](/materials/din-en/c53e "C53E") | [1.1210](/materials/material-no/1.1210 "1.1210") 1.1 | [Steels for surface hardening](/categories/steels-for-surface-hardening "Steels for surface hardening") | 12 | 0,50-0,57 | 0,035 | 0,035 | ≤0,40 | 0,60-0,90 | — | | [1.1213](/materials/material-no/1.1213 "1.1213") | [1.1213](/materials/material-no/1.1213 "1.1213") 1.1 | [Steels for surface hardening](/categories/steels-for-surface-hardening "Steels for surface hardening") | 20 | 0,50-0,57 | 0,035 | 0,025 | 0,15-0,35 | 0,40-0,70 | — | | [C50R](/materials/din-en/c50r "C50R") | [1.1241](/materials/material-no/1.1241 "1.1241") 1.1 | [Steels for surface hardening](/categories/steels-for-surface-hardening "Steels for surface hardening") | 12 | 0,47-0,55 | 0,020-0,040 | 0,03 | ≤0,40 | 0,60-0,90 | ≤0,40 | | [G10500](/materials/uns/g10500 "G10500") | [1.9505](/materials/material-no/1.9505 "1.9505") 1.9 | [Steels for surface hardening](/categories/steels-for-surface-hardening "Steels for surface hardening") | 7 | 0,48-0,55 | 0,05 | 0,03 | — | 0,60-0,90 | — | ## Not sure which one your print means?
