JIS · 2,322 grades # JIS steel grades — 2322 designations — Page 15 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. 3 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2322 designations | Grade | Category | C% by weight | |---|---|---| | [SCS22](/materials/jis/scs22 "SCS22") Indicative | Cast stainless steels | ≤ 0.07 | | [SCS23](/materials/jis/scs23 "SCS23") | Cast stainless steels | ≤ 0.07 | | [SCS24](/materials/jis/scs24 "SCS24") | Cast stainless steels | ≤ 0.07 | | [SCS2A](/materials/jis/scs2a "SCS2A") | Cast stainless steels | 0.25–0.4 | | [SCS3](/materials/jis/scs3 "SCS3") | Cast stainless steels | ≤ 0.15 | | [SCS31](/materials/jis/scs31 "SCS31") | Cast stainless steels | ≤ 0.06 | | [SCS32](/materials/jis/scs32 "SCS32") | Cast stainless steels | ≤ 0.03 | | [SCS33](/materials/jis/scs33 "SCS33") | Cast stainless steels | ≤ 0.03 | | [SCS34](/materials/jis/scs34 "SCS34") | Cast stainless steels | ≤ 0.07 | | [SCS35](/materials/jis/scs35 "SCS35") | Cast stainless steels | ≤ 0.03 | | [SCS35N](/materials/jis/scs35n "SCS35N") | Cast stainless steels | ≤ 0.03 | | [SCS36](/materials/jis/scs36 "SCS36") | Cast stainless steels | ≤ 0.03 | | [SCS36N](/materials/jis/scs36n "SCS36N") | Cast stainless steels | ≤ 0.03 | | [SCS3X](/materials/jis/scs3x "SCS3X") | Cast stainless steels | ≤ 0.1 | | [SCS4](/materials/jis/scs4 "SCS4") | Cast stainless steels | ≤ 0.15 | | [SCS5](/materials/jis/scs5 "SCS5") Indicative | Stainless steels | ≤ 0.05 | | [SCS6](/materials/jis/scs6 "SCS6") | Cast stainless steels | ≤ 0.06 | | [SCS6X](/materials/jis/scs6x "SCS6X") | Cast stainless steels | ≤ 0.06 | | [SCSiMn2](/materials/jis/scsimn2 "SCSiMn2") | Cast steel | 0.25–0.35 | | [SCSiMn2](/materials/jis/scsimn2 "SCSiMn2") Indicative | Quenched and tempered steels | 0.25–0.32 | | [SCW410](/materials/jis/scw410 "SCW410") | Cast steel | ≤ 0.22 | | [SCW410-CF](/materials/jis/scw410-cf "SCW410-CF") | Cast steel | ≤ 0.22 | | [SCW450](/materials/jis/scw450 "SCW450") | Cast steel | ≤ 0.22 | | [SCW480](/materials/jis/scw480 "SCW480") | Cast steel | ≤ 0.22 | | [SCW480-CF](/materials/jis/scw480-cf "SCW480-CF") | Cast steel | ≤ 0.22 | | [SCW490-CF](/materials/jis/scw490-cf "SCW490-CF") | Cast steel | ≤ 0.2 | | [SCW520-CF](/materials/jis/scw520-cf "SCW520-CF") | Cast steel | ≤ 0.2 | | [SCW550](/materials/jis/scw550 "SCW550") | Cast steel | ≤ 0.22 | | [SCW570-CF](/materials/jis/scw570-cf "SCW570-CF") | Cast steel | ≤ 0.2 | | [SCW620](/materials/jis/scw620 "SCW620") | Cast steel | ≤ 0.22 | | [SD295A](/materials/jis/sd295a "SD295A") | Unalloyed structural steels | — | | [SD295B](/materials/jis/sd295b "SD295B") | Unalloyed structural steels | ≤ 0.27 | | [SD345](/materials/jis/sd345 "SD345") | Unalloyed structural steels | ≤ 0.27 | | [SD390](/materials/jis/sd390 "SD390") | Unalloyed structural steels | ≤ 0.29 | | [SD490](/materials/jis/sd490 "SD490") | Unalloyed structural steels | ≤ 0.32 | | [SDP1T](/materials/jis/sdp1t "SDP1T") | — | ≤ 0.25 | | [SDP1TG](/materials/jis/sdp1tg "SDP1TG") | — | ≤ 0.25 | | [SDP2](/materials/jis/sdp2 "SDP2") | — | ≤ 0.25 | | [SDP2G](/materials/jis/sdp2g "SDP2G") | — | ≤ 0.25 | | [SDP3](/materials/jis/sdp3 "SDP3") | — | ≤ 0.12 | | [SDP4](/materials/jis/sdp4 "SDP4") | — | ≤ 0.08 | | [SDP5](/materials/jis/sdp5 "SDP5") | — | ≤ 0.08 | | [SDP6](/materials/jis/sdp6 "SDP6") | — | ≤ 0.08 | | [SDR295](/materials/jis/sdr295 "SDR295") | Unalloyed structural steels | ≤ 0.27 | | [SDR345](/materials/jis/sdr345 "SDR345") | Unalloyed structural steels | ≤ 0.27 | | [SEV245](/materials/jis/sev245 "SEV245") | High-strength steels | ≤ 0.2 | | [SEV295](/materials/jis/sev295 "SEV295") | High-strength steels | ≤ 0.19 | | [SEV345](/materials/jis/sev345 "SEV345") | High-strength steels | ≤ 0.19 | | [SF340A](/materials/jis/sf340a "SF340A") | Unalloyed structural steels | ≤ 0.6 | | [SF390A](/materials/jis/sf390a "SF390A") | Unalloyed structural steels | ≤ 0.6 | **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.
