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 | Ni% | Cr% | C% | S% | Mo% | P% | |---|---|---|---|---|---|---|---|---|---| | [1.4301](/materials/material-no/1.4301 "1.4301") | [1.4301](/materials/material-no/1.4301 "1.4301") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 170 | 8,00-10,5 | 17,5-19,5 | ≤0,07 | 0,015 | — | 0,045 | | [1.4306](/materials/material-no/1.4306 "1.4306") | [1.4306](/materials/material-no/1.4306 "1.4306") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 137 | 10,0-12,0 | 18,0-20,0 | ≤0,030 | 0,015 | — | 0,045 | | [1.4307](/materials/material-no/1.4307 "1.4307") | [1.4307](/materials/material-no/1.4307 "1.4307") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 88 | 8,00-10,5 | 17,5-19,5 | ≤0,030 | 0,015 | — | 0,045 | | [S30400](/materials/uns/s30400 "S30400") | [1.4314](/materials/material-no/1.4314 "1.4314") 1.4 | [Special steels for aviation and aerospace](/categories/special-steels-for-aviation-and-aerospace "Special steels for aviation and aerospace") | 86 | 8,50-10,5 | 17,0-19,0 | ≤0,07 | 0,03 | — | 0,045 | | [1.4404](/materials/material-no/1.4404 "1.4404") | [1.4404](/materials/material-no/1.4404 "1.4404") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 147 | 10,0-13,0 | 16,5-18,2 | ≤0,030 | 0,015 | 2,00-2,50 | 0,045 | | [X2CrNiMo17-12-3](/materials/din-en/x2crnimo17-12-3 "X2CrNiMo17-12-3") | [1.4432](/materials/material-no/1.4432 "1.4432") 1.4 | [Others](/categories/others "Others") | 66 | 10,5-13,0 | 16,5-18,5 | ≤0,030 | 0,015 | 2,50-3,00 | 0,045 | | [1.4435](/materials/material-no/1.4435 "1.4435") | [1.4435](/materials/material-no/1.4435 "1.4435") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 99 | 12,5-15,0 | 17,0-19,0 | ≤0,030 | 0,015 | 2,50-3,00 | 0,045 | | [1.4438](/materials/material-no/1.4438 "1.4438") | [1.4438](/materials/material-no/1.4438 "1.4438") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 49 | 13,0-16,0 | 17,5-19,5 | ≤0,030 | 0,015 | 3,00-4,00 | 0,045 | | [1.4541](/materials/material-no/1.4541 "1.4541") | [1.4541](/materials/material-no/1.4541 "1.4541") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 175 | 9,00-12,0 | 17,0-19,0 | ≤0,08 | 0,015 | — | 0,045 | | [S30347](/materials/uns/s30347 "S30347") | [1.4544](/materials/material-no/1.4544 "1.4544") 1.4 | [Special steels for aviation and aerospace](/categories/special-steels-for-aviation-and-aerospace "Special steels for aviation and aerospace") | 69 | 9,00-11,5 | 17,0-19,0 | ≤0,08 | 0,025 | — | 0,035 | | [X5CrNiNb18-10](/materials/din-en/x5crninb18-10 "X5CrNiNb18-10") | [1.4546](/materials/material-no/1.4546 "1.4546") 1.4 | [Special steels for aviation and aerospace](/categories/special-steels-for-aviation-and-aerospace "Special steels for aviation and aerospace") | 70 | 9,00-11,5 | 17,0-19,0 | ≤0,08 | 0,03 | — | 0,045 | | [1.4550](/materials/material-no/1.4550 "1.4550") | [1.4550](/materials/material-no/1.4550 "1.4550") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 107 | 9,00-12,0 | 17,0-19,0 | ≤0,08 | 0,015 | — | 0,045 | ## Not sure which one your print means?
