JIS · 2,322 grades # JIS steel grades — 2322 designations — Page 46 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 | C% by weight | Also in other standards | |---|---|---| | [SWRCHB320](/materials/jis/swrchb320 "SWRCHB320") | 0.17–0.23 | 1 | | [SWRCHB323](/materials/jis/swrchb323 "SWRCHB323") | 0.2–0.26 | 1 | | [SWRCHB331](/materials/jis/swrchb331 "SWRCHB331") | 0.28–0.34 | 1 | | [SWRCHB334](/materials/jis/swrchb334 "SWRCHB334") | 0.31–0.37 | 1 | | [SWRCHB420](/materials/jis/swrchb420 "SWRCHB420") | 0.17–0.23 | 1 | | [SWRCHB526](/materials/jis/swrchb526 "SWRCHB526") | 0.23–0.29 | 1 | | [SWRCHB620](/materials/jis/swrchb620 "SWRCHB620") | 0.17–0.23 | 1 | | [SWRCHB620](/materials/jis/swrchb620 "SWRCHB620") Indicative | 0.14–0.2 | 3 | | [SWRCHB623](/materials/jis/swrchb623 "SWRCHB623") | 0.2–0.26 | 1 | | [SWRCHB726](/materials/jis/swrchb726 "SWRCHB726") | 0.23–0.29 | 1 | | [SWRCHB734](/materials/jis/swrchb734 "SWRCHB734") | 0.31–0.37 | 1 | | [SWRH27](/materials/jis/swrh27 "SWRH27") | 0.24–0.31 | — | | [SWRH32](/materials/jis/swrh32 "SWRH32") | 0.29–0.36 | — | | [SWRH37](/materials/jis/swrh37 "SWRH37") | 0.34–0.41 | — | | [SWRH42A](/materials/jis/swrh42a "SWRH42A") | 0.39–0.46 | — | | [SWRH42B](/materials/jis/swrh42b "SWRH42B") | 0.39–0.46 | — | | [SWRH47A](/materials/jis/swrh47a "SWRH47A") | 0.44–0.51 | — | | [SWRH47B](/materials/jis/swrh47b "SWRH47B") | 0.44–0.51 | — | | [SWRH52A](/materials/jis/swrh52a "SWRH52A") | 0.49–0.56 | — | | [SWRH52B](/materials/jis/swrh52b "SWRH52B") | 0.49–0.56 | — | | [SWRH57A](/materials/jis/swrh57a "SWRH57A") | 0.54–0.61 | — | | [SWRH57B](/materials/jis/swrh57b "SWRH57B") | 0.54–0.61 | — | | [SWRH62A](/materials/jis/swrh62a "SWRH62A") | 0.59–0.66 | — | | [SWRH62B](/materials/jis/swrh62b "SWRH62B") | 0.59–0.66 | — | | [SWRH67A](/materials/jis/swrh67a "SWRH67A") | 0.64–0.71 | — | | [SWRH67B](/materials/jis/swrh67b "SWRH67B") | 0.64–0.71 | — | | [SWRH67B](/materials/jis/swrh67b "SWRH67B") Indicative | 0.6–0.7 | 10 | | [SWRH72A](/materials/jis/swrh72a "SWRH72A") | 0.69–0.76 | — | | [SWRH72B](/materials/jis/swrh72b "SWRH72B") | 0.69–0.76 | — | | [SWRH77A](/materials/jis/swrh77a "SWRH77A") | 0.74–0.81 | — | | [SWRH77B](/materials/jis/swrh77b "SWRH77B") | 0.74–0.81 | — | | [SWRH82A](/materials/jis/swrh82a "SWRH82A") | 0.79–0.86 | — | | [SWRH82B](/materials/jis/swrh82b "SWRH82B") | 0.79–0.86 | — | | [SWRM10](/materials/jis/swrm10 "SWRM10") | 0.08–0.13 | 1 | | [SWRM12](/materials/jis/swrm12 "SWRM12") | 0.1–0.15 | 1 | | [SWRM15](/materials/jis/swrm15 "SWRM15") | 0.13–0.18 | 1 | | [SWRM17](/materials/jis/swrm17 "SWRM17") | 0.15–0.2 | 1 | | [SWRM2](/materials/jis/swrm2 "SWRM2") | ≤ 0.04 | 1 | | [SWRM20](/materials/jis/swrm20 "SWRM20") | 0.18–0.23 | 1 | | [SWRM22](/materials/jis/swrm22 "SWRM22") | 0.2–0.25 | 1 | | [SWRM4](/materials/jis/swrm4 "SWRM4") | ≤ 0.06 | 1 | | [SWRM6](/materials/jis/swrm6 "SWRM6") | ≤ 0.08 | 1 | | [SWRM6](/materials/jis/swrm6 "SWRM6") Indicative | ≤ 0.03 | 14 | | [SWRM8](/materials/jis/swrm8 "SWRM8") | ≤ 0.1 | 1 | | [SWRS62A](/materials/jis/swrs62a "SWRS62A") | 0.6–0.65 | — | | [SWRS62B](/materials/jis/swrs62b "SWRS62B") | 0.6–0.65 | — | | [SWRS67A](/materials/jis/swrs67a "SWRS67A") | 0.65–0.7 | — | | [SWRS67B](/materials/jis/swrs67b "SWRS67B") | 0.65–0.7 | — | | [SWRS72A](/materials/jis/swrs72a "SWRS72A") | 0.7–0.75 | — | | [SWRS72B](/materials/jis/swrs72b "SWRS72B") | 0.7–0.75 | — | **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.
