UNS · United States · 7 grades # K01802 The designation K01802 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* **Fine-grain structural steels · 50 grades**](/categories/fine-grain-structural-steels "Category: Fine-grain structural steels · 50 grades") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 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 | S% | Mn% | Cu% | C% | N% | P% | |---|---|---|---|---|---|---|---|---|---| | [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 | 0,01 | 0,80-1,50 | ≤0,30 | ≤0,16 | 0,012 | 0,025 | | [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 | 0,015 | 0,80-1,50 | ≤0,30 | ≤0,16 | 0,012 | 0,025 | | [FeE275KTN](/materials/uni/fee275ktn "FeE275KTN") | [1.0491](/materials/material-no/1.0491 "1.0491") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 10 | 0,02 | 0,50-1,50 | ≤0,55 | ≤0,16 | 0,015 | 0,025 | | [S275NH](/materials/din-en/s275nh "S275NH") | [1.0493](/materials/material-no/1.0493 "1.0493") 1.0 | [Others](/categories/others "Others") | 3 | 0,03 | 0,50-1,40 | ≤0,35 | ≤0,20 | 0,015 | 0,035 | | [P315N](/materials/din-en/p315n "P315N") | [1.0505](/materials/material-no/1.0505 "1.0505") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 7 | 0,03 | 0,70-1,50 | ≤0,20 | ≤0,18 | 0,02 | 0,035 | | [P315NH](/materials/din-en/p315nh "P315NH") | [1.0506](/materials/material-no/1.0506 "1.0506") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 7 | 0,03 | 0,70-1,50 | ≤0,20 | ≤0,18 | 0,02 | 0,035 | | [P315NL](/materials/din-en/p315nl "P315NL") | [1.0508](/materials/material-no/1.0508 "1.0508") 1.0 | [Fine-grain structural steels](/categories/fine-grain-structural-steels "Fine-grain structural steels") | 7 | 0,025 | 0,70-1,50 | ≤0,20 | ≤0,16 | 0,02 | 0,03 | ## Not sure which one your print means?
