NEN · 12 grades # NEN steel grades — 12 designations Every grade designated under NEN, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is an indicative cross-reference, not an asserted identity: the grades are close, not interchangeable. Check the composition before you substitute. ## Also known as 12 designations | Grade | Material no. | Category | Also in other standards | |---|---|---|---| | [GG15](/materials/din-en/gg-15 "GG15") | [EN-JL1020](/materials/material-no/en-jl1020 "EN-JL1020") | Others | 22 | | [GG20](/materials/din-en/gg-20 "GG20") | [EN-JL1030](/materials/material-no/en-jl1030 "EN-JL1030") | Others | 22 | | [GG25](/materials/din-en/gg-25 "GG25") | [EN-JL1040](/materials/material-no/en-jl1040 "EN-JL1040") | Others | 22 | | [GG30](/materials/din-en/gg-30 "GG30") | [EN-JL1050](/materials/material-no/en-jl1050 "EN-JL1050") | Others | 22 | | [GG35](/materials/din-en/gg-35 "GG35") | [EN-JL1060](/materials/material-no/en-jl1060 "EN-JL1060") | Others | 21 | | [GN50](/materials/nen/gn50 "GN50") | [EN-JS1082](/materials/material-no/en-js1082 "EN-JS1082") | Others | 20 | | [GN50](/materials/nen/gn50 "GN50") | [EN-JS1083](/materials/material-no/en-js1083 "EN-JS1083") | Others | 20 | | [GN60](/materials/nen/gn60 "GN60") | [EN-JS1060](/materials/material-no/en-js1060 "EN-JS1060") | Others | 20 | | [GN60](/materials/nen/gn60 "GN60") | [EN-JS1092](/materials/material-no/en-js1092 "EN-JS1092") | Others | 20 | | [GN60](/materials/nen/gn60 "GN60") | [EN-JS1093](/materials/material-no/en-js1093 "EN-JS1093") | Others | 20 | | [GN70](/materials/nen/gn70 "GN70") | [EN-JS1102](/materials/material-no/en-js1102 "EN-JS1102") | Others | 21 | | [GN70](/materials/nen/gn70 "GN70") | [EN-JS1103](/materials/material-no/en-js1103 "EN-JS1103") | Others | 21 | **This grade’s own name** — recorded in our sources as this grade’s own designation under that standard. **Indicative** — taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. **Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
