AISI / SAE · United States · 11 grades # 1020 The designation 1020 is carried by 11 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **11** - [*Category* **Unalloyed structural steels · 452 grades**](/categories/unalloyed-structural-steels "Category: Unalloyed structural steels · 452 grades") - [*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 11 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 | Mn% | C% | P% | S% | Si% | Cr% | |---|---|---|---|---|---|---|---|---|---| | [Ust 42-2](/materials/din-en/ust-42-2 "Ust 42-2") | [1.0040](/materials/material-no/1.0040 "1.0040") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 19 | 0,20-0,50 | ≤0,25 | 0,05 | 0,05 | Spuren/Traces | — | | [Fe430B](/materials/iso/fe430b "Fe430B") | [1.0044](/materials/material-no/1.0044 "1.0044") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 130 | ≤1,50 | ≤0,21 | 0,035 | 0,035 | — | — | | [1.0254](/materials/material-no/1.0254 "1.0254") | [1.0254](/materials/material-no/1.0254 "1.0254") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 11 | ≤1,20 | ≤0,16 | 0,025 | 0,02 | ≤0,35 | ≤0,30 | | [E235](/materials/din-en/e235 "E235") | [1.0308](/materials/material-no/1.0308 "1.0308") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 69 | ≤1,20 | ≤0,17 | 0,025 | 0,025 | ≤0,35 | — | | [1.0402](/materials/material-no/1.0402 "1.0402") | [1.0402](/materials/material-no/1.0402 "1.0402") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 94 | 0,40-0,70 | 0,17-0,24 | 0,045 | 0,045 | ≤0,40 | ≤0,40 | | [E255](/materials/din-en/e255 "E255") | [1.0408](/materials/material-no/1.0408 "1.0408") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 10 | 0,40-1,10 | ≤0,21 | 0,025 | 0,025 | ≤0,35 | — | | [C20D](/materials/din-en/c20d "C20D") | [1.0414](/materials/material-no/1.0414 "1.0414") 1.0 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 4 | 0,30-0,60 | 0,18-0,23 | 0,035 | 0,035 | ≤0,30 | ≤0,20 | | [C20D2](/materials/din-en/c20d2 "C20D2") | [1.1137](/materials/material-no/1.1137 "1.1137") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 3 | 0,30-0,50 | 0,18-0,23 | 0,02 | 0,025 | ≤0,30 | ≤0,10 | | [C22R](/materials/din-en/c22r "C22R") | [1.1149](/materials/material-no/1.1149 "1.1149") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 11 | 0,40-0,70 | 0,17-0,24 | 0,035 | 0,020-0,040 | ≤0,40 | ≤0,40 | | [C22E](/materials/din-en/c22e "C22E") | [1.1151](/materials/material-no/1.1151 "1.1151") 1.1 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 27 | 0,40-0,70 | 0,17-0,24 | 0,035 | 0,035 | ≤0,40 | ≤0,40 | | [SAE 1020](/materials/din-en/sae1020 "SAE 1020") | [1.9402](/materials/material-no/1.9402 "1.9402") 1.9 | [Quenched and tempered steels](/categories/quenched-and-tempered-steels "Quenched and tempered steels") | 3 | 0,30-0,60 | 0,18-0,23 | 0,03 | 0,05 | — | — | ## Not sure which one your print means?
