KS · 823 grades # KS steel grades — 823 designations — Page 16 Every grade designated under KS, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is recorded in our sources as this standard’s own designation for the grade. ## Also known as 823 designations | Grade | Category | C% by weight | Also in other standards | |---|---|---|---| | [SWRCH10A](/materials/jis/swrch10a "SWRCH10A") | Cold extrusion steels | 0.08–0.13 | 1 | | [SWRCH10K](/materials/jis/swrch10k "SWRCH10K") | Cold extrusion steels | 0.08–0.13 | 1 | | [SWRCH10R](/materials/jis/swrch10r "SWRCH10R") | Cold extrusion steels | 0.08–0.13 | 1 | | [SWRCH12A](/materials/jis/swrch12a "SWRCH12A") | Cold extrusion steels | 0.1–0.15 | 1 | | [SWRCH12K](/materials/jis/swrch12k "SWRCH12K") | Cold extrusion steels | 0.1–0.15 | 1 | | [SWRCH12R](/materials/jis/swrch12r "SWRCH12R") | Cold extrusion steels | 0.1–0.15 | 1 | | [SWRCH15A](/materials/ks/swrch15a "SWRCH15A") | Unalloyed structural steels | 0.13–0.17 | 7 | | [SWRCH15K](/materials/jis/swrch15k "SWRCH15K") | Cold extrusion steels | 0.13–0.18 | 1 | | [SWRCH15R](/materials/jis/swrch15r "SWRCH15R") | Cold extrusion steels | 0.13–0.18 | 1 | | [SWRCH16A](/materials/jis/swrch16a "SWRCH16A") | Cold extrusion steels | 0.13–0.18 | 1 | | [SWRCH16K](/materials/jis/swrch16k "SWRCH16K") | Cold extrusion steels | 0.13–0.18 | 1 | | [SWRCH17K](/materials/jis/swrch17k "SWRCH17K") | Cold extrusion steels | 0.15–0.2 | 1 | | [SWRCH17R](/materials/jis/swrch17r "SWRCH17R") | Cold extrusion steels | 0.15–0.2 | 1 | | [SWRCH18A](/materials/jis/swrch18a "SWRCH18A") | Cold extrusion steels | 0.15–0.2 | 1 | | [SWRCH18K](/materials/jis/swrch18k "SWRCH18K") | Cold extrusion steels | 0.15–0.2 | 1 | | [SWRCH19A](/materials/jis/swrch19a "SWRCH19A") | Cold extrusion steels | 0.15–0.2 | 1 | | [SWRCH20A](/materials/jis/swrch20a "SWRCH20A") | Cold extrusion steels | 0.18–0.23 | 1 | | [SWRCH20K](/materials/jis/swrch20k "SWRCH20K") | Cold extrusion steels | 0.18–0.23 | 1 | | [SWRCH22A](/materials/jis/swrch22a "SWRCH22A") | Cold extrusion steels | 0.18–0.23 | 1 | | [SWRCH22K](/materials/jis/swrch22k "SWRCH22K") | Cold extrusion steels | 0.18–0.23 | 1 | | [SWRCH24K](/materials/jis/swrch24k "SWRCH24K") | Cold extrusion steels | 0.19–0.25 | 1 | | [SWRCH25A](/materials/jis/swrch25a "SWRCH25A") | Cold extrusion steels | 0.22–0.28 | 1 | | [SWRCH25K](/materials/jis/swrch25k "SWRCH25K") | Cold extrusion steels | 0.22–0.28 | 1 | | [SWRCH27K](/materials/jis/swrch27k "SWRCH27K") | Cold extrusion steels | 0.22–0.29 | 1 | | [SWRCH30K](/materials/jis/swrch30k "SWRCH30K") | Cold extrusion steels | 0.27–0.33 | 1 | | [SWRCH33K](/materials/jis/swrch33k "SWRCH33K") | Cold extrusion steels | 0.3–0.36 | 1 | | [SWRCH35K](/materials/jis/swrch35k "SWRCH35K") | Cold extrusion steels | 0.32–0.38 | 1 | | [SWRCH38K](/materials/jis/swrch38k "SWRCH38K") | Cold extrusion steels | 0.35–0.41 | 1 | | [SWRCH40K](/materials/jis/swrch40k "SWRCH40K") | Cold extrusion steels | 0.37–0.43 | 1 | | [SWRCH41K](/materials/jis/swrch41k "SWRCH41K") | Cold extrusion steels | 0.36–0.44 | 1 | | [SWRCH43K](/materials/jis/swrch43k "SWRCH43K") | Cold extrusion steels | 0.4–0.46 | 1 | | [SWRCH45K](/materials/jis/swrch45k "SWRCH45K") | Cold extrusion steels | 0.42–0.48 | 1 | | [SWRCH48K](/materials/jis/swrch48k "SWRCH48K") | Cold extrusion steels | 0.45–0.51 | 1 | | [SWRCH50K](/materials/jis/swrch50k "SWRCH50K") | Cold extrusion steels | 0.47–0.53 | 1 | | [SWRCH6A](/materials/jis/swrch6a "SWRCH6A") | Cold extrusion steels | ≤ 0.08 | 1 | | [SWRCH6R](/materials/jis/swrch6r "SWRCH6R") | Cold extrusion steels | ≤ 0.08 | 1 | | [SWRCH8A](/materials/jis/swrch8a "SWRCH8A") | Cold extrusion steels | ≤ 0.1 | 1 | | [SWRCH8R](/materials/jis/swrch8r "SWRCH8R") | Cold extrusion steels | ≤ 0.1 | 1 | | [SWRCHB220](/materials/ks/swrchb220 "SWRCHB220") | — | 0.17–0.23 | — | | [SWRCHB223](/materials/jis/swrchb223 "SWRCHB223") | Cold extrusion steels | 0.2–0.26 | 1 | | [SWRCHB226](/materials/ks/swrchb226 "SWRCHB226") | — | 0.23–0.29 | — | | [SWRCHB231](/materials/ks/swrchb231 "SWRCHB231") | — | 0.28–0.34 | — | | [SWRCHB234](/materials/ks/swrchb234 "SWRCHB234") | — | 0.31–0.37 | — | | [SWRCHB237](/materials/jis/swrchb237 "SWRCHB237") | Cold extrusion steels | 0.34–0.4 | 1 | | [SWRCHB320](/materials/jis/swrchb320 "SWRCHB320") | Cold extrusion steels | 0.17–0.23 | 1 | | [SWRCHB323](/materials/jis/swrchb323 "SWRCHB323") | Cold extrusion steels | 0.2–0.26 | 1 | | [SWRCHB331](/materials/jis/swrchb331 "SWRCHB331") | Cold extrusion steels | 0.28–0.34 | 1 | | [SWRCHB334](/materials/jis/swrchb334 "SWRCHB334") | Cold extrusion steels | 0.31–0.37 | 1 | | [SWRCHB420](/materials/jis/swrchb420 "SWRCHB420") | Cold extrusion steels | 0.17–0.23 | 1 | | [SWRCHB423](/materials/ks/swrchb423 "SWRCHB423") | — | 0.2–0.26 | — | **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.
