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% | N% | |---|---|---|---|---|---|---|---|---|---| | [RSt 42-2](/materials/din-en/rst42-2 "RSt 42-2") | [1.0042](/materials/material-no/1.0042 "1.0042") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 6 | 0,20-0,50 | ≤0,23 | 0,03-0,30 | 0,05 | 0,05 | 0,007 | | [S235J2G3](/materials/din-en/s235j2g3 "S235J2G3") | [1.0116](/materials/material-no/1.0116 "1.0116") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 66 | ≤1,40 | ≤0,17 | — | 0,035 | 0,035 | — | | [1.0144](/materials/material-no/1.0144 "1.0144") | [1.0144](/materials/material-no/1.0144 "1.0144") 1.0 | [Unalloyed structural steels](/categories/unalloyed-structural-steels "Unalloyed structural steels") | 64 | ≤1,50 | ≤0,18 | — | 0,035 | 0,035 | — | | [1.0345](/materials/material-no/1.0345 "1.0345") | [1.0345](/materials/material-no/1.0345 "1.0345") 1.0 | [Heat-resistant structural steels](/categories/heat-resistant-structural-steels "Heat-resistant structural steels") | 62 | 0,60-1,20 | ≤0,16 | ≤0,35 | 0,025 | 0,01 | 0,012 | | [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 | 0,70-1,50 | ≤0,18 | ≤0,45 | 0,035 | 0,03 | 0,02 | | [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 | 0,70-1,50 | ≤0,18 | ≤0,45 | 0,035 | 0,03 | 0,02 | | [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 | 0,70-1,50 | ≤0,16 | ≤0,45 | 0,03 | 0,025 | 0,02 | | [Fe510D1KI](/materials/din-en/fe510d1ki "Fe510D1KI") | [1.8946](/materials/material-no/1.8946 "1.8946") 1.8 | [Weathering steels](/categories/weathering-steels "Weathering steels") | 7 | ≤1,00 | ≤0,12 | ≤0,75 | 0,06-0,15 | 0,03 | — | | [A709-50W](/materials/din-en/a709-50w "A709-50W") | [1.8959](/materials/material-no/1.8959 "1.8959") 1.8 | [Weathering steels](/categories/weathering-steels "Weathering steels") | 23 | 0,50-1,50 | ≤0,16 | ≤0,50 | 0,035 | 0,035 | 0,009 | ## Not sure which one your print means?
