IS · 111 grades # IS steel grades — 111 designations — Page 2 Every grade designated under IS, 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 111 designations | Grade | C% by weight | |---|---| | [E250BR](/materials/is/e250br "E250BR") | ≤ 0.22 | | [E250C](/materials/is/e250c "E250C") | ≤ 0.2 | | [E250S](/materials/is/e250s "E250S") | ≤ 0.2 | | [E275A](/materials/is/e275-a "E275A") | ≤ 0.23 | | [E275B0](/materials/is/e275b0 "E275B0") | ≤ 0.22 | | [E275BR](/materials/is/e275br "E275BR") | ≤ 0.22 | | [E275C](/materials/is/e275c "E275C") | ≤ 0.2 | | [E300A](/materials/is/e300a "E300A") | ≤ 0.2 | | [E300B0](/materials/is/e300b0 "E300B0") | ≤ 0.2 | | [E300BR](/materials/is/e300br "E300BR") | ≤ 0.2 | | [E300C](/materials/is/e300c "E300C") | ≤ 0.2 | | [E300S](/materials/is/e300s "E300S") | ≤ 0.2 | | [E350A](/materials/is/e350a "E350A") | ≤ 0.2 | | [E350B0](/materials/is/e350b0 "E350B0") | ≤ 0.2 | | [E350BR](/materials/is/e350br "E350BR") | ≤ 0.2 | | [E350C](/materials/is/e350c "E350C") | ≤ 0.2 | | [E350S](/materials/is/e350s "E350S") | ≤ 0.2 | | [E410A](/materials/is/e410a "E410A") | ≤ 0.2 | | [E410B0](/materials/is/e410b0 "E410B0") | ≤ 0.2 | | [E410BR](/materials/is/e410br "E410BR") | ≤ 0.2 | | [E410C](/materials/is/e410c "E410C") | ≤ 0.2 | | [E450A](/materials/is/e450a "E450A") | ≤ 0.22 | | [E450BR](/materials/is/e450br "E450BR") | ≤ 0.22 | | [E450S](/materials/is/e450s "E450S") | ≤ 0.22 | | [E550A](/materials/is/e550a "E550A") | ≤ 0.22 | | [E550BR](/materials/is/e550br "E550BR") | ≤ 0.22 | | [E600A](/materials/is/e600a "E600A") | ≤ 0.22 | | [E600BR](/materials/is/e600br "E600BR") | ≤ 0.22 | | [E650A](/materials/is/e650a "E650A") | ≤ 0.22 | | [E650BR](/materials/is/e650br "E650BR") | ≤ 0.22 | | [H235](/materials/is/h235 "H235") | — | | [H265](/materials/is/h265 "H265") | — | | [H295](/materials/is/h295 "H295") | — | | [H355](/materials/is/h355 "H355") | — | | [HR0](/materials/is/hr0 "HR0") | — | | [HR1](/materials/is/hr1 "HR1") | — | | [HR2](/materials/is/hr2 "HR2") | — | | [HR3](/materials/is/hr3 "HR3") | — | | [HR4](/materials/is/hr4 "HR4") | — | | [HR5](/materials/is/hr5 "HR5") | — | | [R220](/materials/is/r220 "R220") | — | | [R260](/materials/is/r260 "R260") | — | | [R275](/materials/is/r275 "R275") | — | | [R355](/materials/is/r355 "R355") | — | | [X02Cr17Ni12Mo2](/materials/is/x02cr17ni12mo2 "X02Cr17Ni12Mo2") | ≤ 0.03 | | [X02Cr19Ni10](/materials/is/x02cr19ni10 "X02Cr19Ni10") | ≤ 0.03 | | [X04Cr12](/materials/is/x04cr12 "X04Cr12") | ≤ 0.08 | | [X04Cr17Ni12Mo2](/materials/is/x04cr17ni12mo2 "X04Cr17Ni12Mo2") | ≤ 0.08 | | [X04Cr17Ni12Mo2Ti](/materials/is/x04cr17ni12mo2ti "X04Cr17Ni12Mo2Ti") | ≤ 0.08 | | [X04Cr18Ni10Nb](/materials/is/x04cr18ni10nb "X04Cr18Ni10Nb") | ≤ 0.08 | **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.
