JIS · 2,322 grades # JIS steel grades — 2322 designations — Page 42 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. 5 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2322 designations | Grade | Category | C% by weight | |---|---|---| | [SUS440F](/materials/jis/sus440f "SUS440F") | Stainless steels | 0.95–1.2 | | [SUS443J1](/materials/jis/sus443j1 "SUS443J1") | Stainless steels | ≤ 0.025 | | [SUS444](/materials/jis/sus444 "SUS444") Indicative | Stainless steels | ≤ 0.025 | | [SUS444](/materials/jis/sus444 "SUS444") Indicative | Heat resistant steels | ≤ 0.03 | | [SUS444](/materials/jis/sus444 "SUS444") Indicative | Others | ≤ 0.03 | | [SUS444](/materials/jis/sus444 "SUS444") Indicative | Others | ≤ 0.03 | | [SUS444TB](/materials/jis/sus444tb "SUS444TB") | Stainless steels | ≤ 0.025 | | [SUS444TKA](/materials/jis/sus444tka "SUS444TKA") | Stainless steels | ≤ 0.025 | | [SUS444TP](/materials/jis/sus444tp "SUS444TP") | Stainless steels | ≤ 0.025 | | [SUS445J1](/materials/jis/sus445j1 "SUS445J1") | Stainless steels | ≤ 0.025 | | [SUS445J1TKC](/materials/jis/sus445j1tkc "SUS445J1TKC") | Stainless steels | ≤ 0.025 | | [SUS445J2](/materials/jis/sus445j2 "SUS445J2") | Stainless steels | ≤ 0.025 | | [SUS447J1](/materials/jis/sus447j1 "SUS447J1") | Stainless steels | ≤ 0.01 | | [SUS630FB](/materials/jis/sus630fb "SUS630FB") | Stainless steels | ≤ 0.07 | | [SUS630TKA](/materials/jis/sus630tka "SUS630TKA") | Stainless steels | ≤ 0.07 | | [SUS631](/materials/jis/sus631 "SUS631") Indicative | Stainless steels | ≤ 0.09 | | [SUS631-CSP](/materials/jis/sus631-csp "SUS631-CSP") | Stainless steels | ≤ 0.09 | | [SUS631J1](/materials/jis/sus631j1 "SUS631J1") | Stainless steels | ≤ 0.09 | | [SUS631J1-CSP](/materials/jis/sus631j1-csp "SUS631J1-CSP") | Stainless steels | ≤ 0.09 | | [SUS631TKA](/materials/jis/sus631tka "SUS631TKA") | Stainless steels | ≤ 0.09 | | [SUS821L1TKA](/materials/jis/sus821l1tka "SUS821L1TKA") | Stainless steels | ≤ 0.03 | | [SUS821L1TP](/materials/jis/sus821l1tp "SUS821L1TP") | Stainless steels | ≤ 0.03 | | [SUS821L1TPY](/materials/jis/sus821l1tpy "SUS821L1TPY") | Stainless steels | ≤ 0.03 | | [SUS836L](/materials/jis/sus836l "SUS836L") | Stainless steels | ≤ 0.03 | | [SUS836LTB](/materials/jis/sus836ltb "SUS836LTB") | Stainless steels | ≤ 0.03 | | [SUS836LTP](/materials/jis/sus836ltp "SUS836LTP") | Stainless steels | ≤ 0.03 | | [SUS890L](/materials/jis/sus890l "SUS890L") | Stainless steels | ≤ 0.02 | | [SUS890LTB](/materials/jis/sus890ltb "SUS890LTB") | Stainless steels | ≤ 0.02 | | [SUS890LTP](/materials/jis/sus890ltp "SUS890LTP") | Stainless steels | ≤ 0.02 | | [SUSF304](/materials/jis/susf304 "SUSF304") | Stainless steels | ≤ 0.08 | | [SUSF304H](/materials/jis/susf304h "SUSF304H") | Stainless steels | 0.04–0.1 | | [SUSF304L](/materials/jis/susf304l "SUSF304L") | Stainless steels | ≤ 0.03 | | [SUSF304LN](/materials/jis/susf304ln "SUSF304LN") | Stainless steels | ≤ 0.03 | | [SUSF304N](/materials/jis/susf304n "SUSF304N") | Stainless steels | ≤ 0.08 | | [SUSF310](/materials/jis/susf310 "SUSF310") | Stainless steels | ≤ 0.15 | | [SUSF316](/materials/jis/susf316 "SUSF316") | Stainless steels | ≤ 0.08 | | [SUSF316H](/materials/jis/susf316h "SUSF316H") | Stainless steels | 0.04–0.1 | | [SUSF316L](/materials/jis/susf316l "SUSF316L") | Stainless steels | ≤ 0.03 | | [SUSF316LN](/materials/jis/susf316ln "SUSF316LN") | Stainless steels | ≤ 0.03 | | [SUSF316N](/materials/jis/susf316n "SUSF316N") | Stainless steels | ≤ 0.08 | | [SUSF317](/materials/jis/susf317 "SUSF317") | Stainless steels | ≤ 0.08 | | [SUSF317L](/materials/jis/susf317l "SUSF317L") | Stainless steels | ≤ 0.03 | | [SUSF321](/materials/jis/susf321 "SUSF321") | Stainless steels | ≤ 0.08 | | [SUSF321H](/materials/jis/susf321h "SUSF321H") | Stainless steels | 0.04–0.1 | | [SUSF347](/materials/jis/susf347 "SUSF347") | Stainless steels | ≤ 0.08 | | [SUSF347H](/materials/jis/susf347h "SUSF347H") | Stainless steels | 0.04–0.1 | | [SUSF410-A](/materials/jis/susf410-a "SUSF410-A") | Stainless steels | ≤ 0.15 | | [SUSF410-B](/materials/jis/susf410-b "SUSF410-B") | Stainless steels | ≤ 0.15 | | [SUSF410-C](/materials/jis/susf410-c "SUSF410-C") | Stainless steels | ≤ 0.15 | | [SUSF410-D](/materials/jis/susf410-d "SUSF410-D") | Stainless steels | ≤ 0.15 | **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.
