JIS · 2,322 grades # JIS steel grades — 2322 designations — Page 41 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. 16 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2322 designations | Grade | Category | C% by weight | Also in other standards | |---|---|---|---| | [SUS410TK](/materials/jis/sus410tk "SUS410TK") Indicative | Stainless steels | 0.08–0.15 | 26 | | [SUS410TKA](/materials/jis/sus410tka "SUS410TKA") | Stainless steels | ≤ 0.15 | — | | [SUS410TKC](/materials/jis/sus410tkc "SUS410TKC") | Stainless steels | ≤ 0.15 | — | | [SUS416](/materials/jis/sus416 "SUS416") Indicative | Stainless steels | 0.08–0.15 | 14 | | [SUS416TKA](/materials/jis/sus416tka "SUS416TKA") | Stainless steels | ≤ 0.15 | — | | [SUS420F](/materials/jis/sus420f "SUS420F") | — | — | — | | [SUS420F przybliż.](/materials/jis/sus420f-przybliz "SUS420F przybliż.")
