UNS · United States · 7 grades # K02100 The designation K02100 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* **Aging resistant steels · 2 grades**](/categories/aging-resistant-steels "Category: Aging resistant steels · 2 grades") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - [*Category* **Fine-grain structural steels · 50 grades**](/categories/fine-grain-structural-steels "Category: Fine-grain structural steels · 50 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 | Mn% | C% | Si% | P% | S% | Nb% | |---|---|---|---|---|---|---|---|---|---| | [P280GH](/materials/din-en/p280gh "P280GH") | [1.0426](/materials/material-no/1.0426 "1.0426") 1.0 | [Aging resistant steels](/categories/aging-resistant-steels "Aging resistant steels") | 56 | 0,90-1,50 | 0,08-0,20 | ≤0,40 | 0,025 | 0,015 | ≤0,01 | | [1.0437](/materials/material-no/1.0437 "1.0437") | [1.0437](/materials/material-no/1.0437 "1.0437") 1.0 | [Others](/categories/others "Others") | 21 | ≥0,70 | ≤0,20 | ≤0,50 | 0,025 | 0,015 | ≤0,050 | | [1.0486](/materials/material-no/1.0486 "1.0486") | [1.0486](/materials/material-no/1.0486 "1.0486") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 18 | 0,80-1,50 | ≤0,16 | ≤0,40 | 0,025 | 0,01 | ≤0,05 | | [P275NH](/materials/din-en/p275nh "P275NH") | [1.0487](/materials/material-no/1.0487 "1.0487") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 10 | 0,80-1,50 | ≤0,16 | ≤0,40 | 0,025 | 0,015 | ≤0,05 | | [A662Gr.A](/materials/din-en/a662gr-a "A662Gr.A") | [1.0488](/materials/material-no/1.0488 "1.0488") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 18 | 0,60-1,50 | ≤0,16 | ≤0,40 | 0,025 | 0,015 | ≤0,05 | | [EStE 285](/materials/din-en/este-285 "EStE 285") | [1.1104](/materials/material-no/1.1104 "1.1104") 1.1 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 5 | 0,60-1,50 | ≤0,16 | ≤0,40 | 0,02 | 0,01 | ≤0,05 | | [A 516 Grade 60](/materials/din-en/a-516-grade-60 "A 516 Grade 60") | [1.9417](/materials/material-no/1.9417 "1.9417") 1.9 | [Aging resistant steels](/categories/aging-resistant-steels "Aging resistant steels") | 2 | 0,60-1,20 | ≤0,21 | 0,15-0,40 | 0,035 | 0,035 | — | ## Not sure which one your print means?
