ASTM · United States · 11 grades # A924 The designation A924 is carried by 11 different grades. Compare them on the elements that actually differ, then open the one your print means. - *Matching grades* **11** - [*Category* **Stainless steels · 468 grades**](/categories/stainless-steels "Category: Stainless steels · 468 grades") - [*Category* **Heat resistant steels · 64 grades**](/categories/heat-resistant-steels "Category: Heat resistant steels · 64 grades") - [*Category* **Low-temperature steels · 4 grades**](/categories/low-temperature-steels "Category: Low-temperature steels · 4 grades") [Search](/search "Steel grade search")[Inquiry](/inquiry "Inquiry") ## Which of the 11 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 | Ni% | C% | Cr% | N% | Si% | 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 | ≤0,07 | 17,5-19,5 | 0,11 | ≤1,00 | 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 | ≤0,030 | 18,0-20,0 | 0,11 | ≤1,00 | 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 | ≤0,030 | 17,5-19,5 | 0,11 | ≤1,00 | 0,045 | | [1.4311](/materials/material-no/1.4311 "1.4311") | [1.4311](/materials/material-no/1.4311 "1.4311") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 55 | 8,50-11,50 | ≤0,030 | 17,5-19,5 | 0,12-0,22 | ≤1,00 | 0,045 | | [X5CrNiN19-9](/materials/din-en/x5crnin19-9 "X5CrNiN19-9") | [1.4315](/materials/material-no/1.4315 "1.4315") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 26 | 8,00-11,0 | ≤0,06 | 18,0-20,0 | 0,12-0,22 | ≤1,00 | 0,045 | | [X1CrNi25-21](/materials/din-en/x1crni25-21 "X1CrNi25-21") | [1.4335](/materials/material-no/1.4335 "1.4335") 1.4 | [Stainless steels](/categories/stainless-steels "Stainless steels") | 36 | 20,0-22,0 | ≤0,020 | 24,0-26,0 | 0,11 | ≤0,25 | 0,025 | | [X 7 CrNi 23 14](/materials/din-en/x-7-crni-23-14 "X 7 CrNi 23 14") | [1.4833](/materials/material-no/1.4833 "1.4833") 1.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 69 | 12,0-14,0 | ≤0,15 | 22,0-24,0 | 0,11 | ≤1,00 | 0,045 | | [1.4845](/materials/material-no/1.4845 "1.4845") | [1.4845](/materials/material-no/1.4845 "1.4845") 1.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 91 | 19,0-22,0 | ≤0,10 | 24,0-26,0 | 0,11 | ≤1,50 | 0,045 | | [X6CrNi23-13](/materials/din-en/x6crni23-13 "X6CrNi23-13") | [1.4950](/materials/material-no/1.4950 "1.4950") 1.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 32 | 12,0-15,0 | 0,04-0,08 | 22,0-24,0 | 0,11 | ≤0,70 | 0,035 | | [X6CrNi25-20](/materials/din-en/x6crni25-20 "X6CrNi25-20") | [1.4951](/materials/material-no/1.4951 "1.4951") 1.4 | [Heat resistant steels](/categories/heat-resistant-steels "Heat resistant steels") | 34 | 19,0-22,0 | 0,04-0,08 | 24,0-26,0 | 0,1 | ≤0,70 | 0,035 | | [X3CrNiN18-10](/materials/din-en/x3crnin18-10 "X3CrNiN18-10") | [1.6907](/materials/material-no/1.6907 "1.6907") 1.6 | [Low-temperature steels](/categories/low-temperature-steels "Low-temperature steels") | 26 | 9,00-11,5 | ≤0,04 | 17,0-19,0 | 0,10-0,18 | ≤1,00 | 0,045 | ## Not sure which one your print means?
