JIS · 2,322 grades # JIS steel grades — 2322 designations — Page 43 Every grade designated under JIS, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Unless marked, every name here is an asserted identity — the same grade under this standard’s own designation. 1 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2322 designations | Grade | Category | C% by weight | |---|---|---| | [SUSF630](/materials/jis/susf630 "SUSF630") | Stainless steels | ≤ 0.07 | | [SUSF6B](/materials/jis/susf6b "SUSF6B") | Stainless steels | ≤ 0.15 | | [SUSF6NM](/materials/jis/susf6nm "SUSF6NM") | Stainless steels | ≤ 0.05 | | [SUSXM15J1](/materials/jis/susxm15j1 "SUSXM15J1") | Stainless steels | ≤ 0.08 | | [SUSXM15J1TB](/materials/jis/susxm15j1tb "SUSXM15J1TB") | Stainless steels | ≤ 0.08 | | [SUSXM27](/materials/jis/susxm27 "SUSXM27") | Stainless steels | ≤ 0.01 | | [SUSXM27TB](/materials/jis/susxm27tb "SUSXM27TB") | Stainless steels | ≤ 0.01 | | [SUSXM7](/materials/jis/susxm7 "SUSXM7") Indicative | Stainless steels | ≤ 0.04 | | [SUSXM8TB](/materials/jis/susxm8tb "SUSXM8TB") | Stainless steels | ≤ 0.08 | | [SUSY16-8-2](/materials/jis/susy16-8-2 "SUSY16-8-2") | Stainless steels | ≤ 0.1 | | [SUSY308](/materials/jis/susy308 "SUSY308") | Stainless steels | ≤ 0.08 | | [SUSY308L](/materials/jis/susy308l "SUSY308L") | Stainless steels | ≤ 0.03 | | [SUSY309](/materials/jis/susy309 "SUSY309") | Stainless steels | ≤ 0.12 | | [SUSY309L](/materials/jis/susy309l "SUSY309L") | Stainless steels | ≤ 0.03 | | [SUSY309Mo](/materials/jis/susy309mo "SUSY309Mo") | Stainless steels | ≤ 0.12 | | [SUSY310S](/materials/jis/susy310s "SUSY310S") | Stainless steels | ≤ 0.08 | | [SUSY312](/materials/jis/susy312 "SUSY312") | Stainless steels | ≤ 0.15 | | [SUSY316](/materials/jis/susy316 "SUSY316") | Stainless steels | ≤ 0.08 | | [SUSY316J1L](/materials/jis/susy316j1l "SUSY316J1L") | Stainless steels | ≤ 0.03 | | [SUSY316L](/materials/jis/susy316l "SUSY316L") | Stainless steels | ≤ 0.03 | | [SUSY317](/materials/jis/susy317 "SUSY317") | Stainless steels | ≤ 0.08 | | [SUSY317L](/materials/jis/susy317l "SUSY317L") | Stainless steels | ≤ 0.03 | | [SUSY321](/materials/jis/susy321 "SUSY321") | Stainless steels | ≤ 0.08 | | [SUSY347](/materials/jis/susy347 "SUSY347") | Stainless steels | ≤ 0.08 | | [SUSY347L](/materials/jis/susy347l "SUSY347L") | Stainless steels | ≤ 0.03 | | [SUSY410](/materials/jis/susy410 "SUSY410") | Stainless steels | ≤ 0.12 | | [SUSY430](/materials/jis/susy430 "SUSY430") | Stainless steels | ≤ 0.1 | | [SWCH10A](/materials/jis/swch10a "SWCH10A") | Cold extrusion steels | — | | [SWCH10K](/materials/jis/swch10k "SWCH10K") | Cold extrusion steels | — | | [SWCH10R](/materials/jis/swch10r "SWCH10R") | Cold extrusion steels | — | | [SWCH12A](/materials/jis/swch12a "SWCH12A") | Cold extrusion steels | — | | [SWCH12K](/materials/jis/swch12k "SWCH12K") | Cold extrusion steels | — | | [SWCH12R](/materials/jis/swch12r "SWCH12R") | Cold extrusion steels | — | | [SWCH15A](/materials/jis/swch15a "SWCH15A") | Cold extrusion steels | — | | [SWCH15K](/materials/jis/swch15k "SWCH15K") | Cold extrusion steels | — | | [SWCH15R](/materials/jis/swch15r "SWCH15R") | Cold extrusion steels | — | | [SWCH16A](/materials/jis/swch16a "SWCH16A") | Cold extrusion steels | — | | [SWCH16K](/materials/jis/swch16k "SWCH16K") | Cold extrusion steels | — | | [SWCH17K](/materials/jis/swch17k "SWCH17K") | Cold extrusion steels | — | | [SWCH17R](/materials/jis/swch17r "SWCH17R") | Cold extrusion steels | — | | [SWCH18A](/materials/jis/swch18a "SWCH18A") | Cold extrusion steels | — | | [SWCH18K](/materials/jis/swch18k "SWCH18K") | Cold extrusion steels | — | | [SWCH19A](/materials/jis/swch19a "SWCH19A") | Cold extrusion steels | — | | [SWCH20A](/materials/jis/swch20a "SWCH20A") | Cold extrusion steels | — | | [SWCH20K](/materials/jis/swch20k "SWCH20K") | Cold extrusion steels | — | | [SWCH22A](/materials/jis/swch22a "SWCH22A") | Cold extrusion steels | — | | [SWCH22K](/materials/jis/swch22k "SWCH22K") | Cold extrusion steels | — | | [SWCH24K](/materials/jis/swch24k "SWCH24K") | Cold extrusion steels | — | | [SWCH25A](/materials/jis/swch25a "SWCH25A") | Cold extrusion steels | — | | [SWCH25K](/materials/jis/swch25k "SWCH25K") | Cold extrusion steels | — | **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.
