GB · 1,318 grades # GB steel grades — 1318 designations — Page 2 Every grade designated under GB, 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. 6 of 50 rows differ and carry an “Indicative” mark. ## Also known as 1318 designations | Grade | C% by weight | |---|---| | [022Cr19Ni16Mo5N](/materials/gb/022cr19ni16mo5n "022Cr19Ni16Mo5N") | ≤ 0.03 | | [022Cr19Ni5Mo3Si2N](/materials/gb/022cr19ni5mo3si2n "022Cr19Ni5Mo3Si2N") | ≤ 0.03 | | [022Cr21Mn3Ni3Mo2N](/materials/gb/022cr21mn3ni3mo2n "022Cr21Mn3Ni3Mo2N") | ≤ 0.03 | | [022Cr21Mn5Ni2N](/materials/gb/022cr21mn5ni2n "022Cr21Mn5Ni2N") | ≤ 0.03 | | [022Cr21Ni25Mo7N](/materials/gb/022cr21ni25mo7n "022Cr21Ni25Mo7N") | ≤ 0.03 | | [022Cr21Ni3Mo2N](/materials/gb/022cr21ni3mo2n "022Cr21Ni3Mo2N") | ≤ 0.03 | | [022Cr22Mn3Ni2MoN](/materials/gb/022cr22mn3ni2mon "022Cr22Mn3Ni2MoN") | ≤ 0.03 | | [022Cr22Ni5Mo3N](/materials/gb/022cr22ni5mo3n "022Cr22Ni5Mo3N") | ≤ 0.03 | | [022Cr23Ni4MoCuN](/materials/gb/022cr23ni4mocun "022Cr23Ni4MoCuN") Indicative | ≤ 0.03 | | [022Cr23Ni5Mo3N](/materials/gb/022cr23ni5mo3n "022Cr23Ni5Mo3N") | ≤ 0.03 | | [022Cr24Ni17Mo5Mn6NbN](/materials/gb/022cr24ni17mo5mn6nbn "022Cr24Ni17Mo5Mn6NbN") | ≤ 0.03 | | [022Cr25Ni22Mo2N](/materials/gb/022cr25ni22mo2n "022Cr25Ni22Mo2N") | ≤ 0.02 | | [022Cr25Ni6Mo2N](/materials/gb/022cr25ni6mo2n "022Cr25Ni6Mo2N") | ≤ 0.03 | | [022Cr25Ni7Mo3WCuN](/materials/gb/022cr25ni7mo3wcun "022Cr25Ni7Mo3WCuN") | ≤ 0.03 | | [022Cr25Ni7Mo4N](/materials/gb/022cr25ni7mo4n "022Cr25Ni7Mo4N") | ≤ 0.03 | | [022Cr25Ni7Mo4WCuN](/materials/gb/022cr25ni7mo4wcun "022Cr25Ni7Mo4WCuN") | ≤ 0.03 | | [022Cr29Mo4NbTi](/materials/gb/022cr29mo4nbti "022Cr29Mo4NbTi") | ≤ 0.03 | | [026Cr24](/materials/gb/026cr24 "026Cr24") | ≤ 0.035 | | [03Cr18Ni16Mo5](/materials/gb/03cr18ni16mo5 "03Cr18Ni16Mo5") | ≤ 0.04 | | [03Cr22Mn5Ni2MoCuN](/materials/gb/03cr22mn5ni2mocun "03Cr22Mn5Ni2MoCuN") | ≤ 0.04 | | [03Cr25Ni6Mo3Cu2N](/materials/gb/03cr25ni6mo3cu2n "03Cr25Ni6Mo3Cu2N") | ≤ 0.04 | | [04Cr11Nb](/materials/gb/04cr11nb "04Cr11Nb") | ≤ 0.06 | | [04Cr12Ni8Cu2TiNb](/materials/gb/04cr12ni8cu2tinb "04Cr12Ni8Cu2TiNb") | ≤ 0.05 | | [04Cr13Ni5Mo](/materials/gb/04cr13ni5mo "04Cr13Ni5Mo") | ≤ 0.05 | | [04Cr13Ni8Mo2Al](/materials/gb/04cr13ni8mo2al "04Cr13Ni8Mo2Al") | ≤ 0.05 | | [05Cr15Ni5Cu4Nb](/materials/gb/05cr15ni5cu4nb "05Cr15Ni5Cu4Nb") | ≤ 0.07 | | [05Cr17Ni4Cu4Nb](/materials/gb/05cr17ni4cu4nb "05Cr17Ni4Cu4Nb") | ≤ 0.07 | | [05Cr19Ni10Si2CeN](/materials/gb/05cr19ni10si2cen "05Cr19Ni10Si2CeN") | 0.04–0.06 | | [06Cr11Ti](/materials/gb/06cr11ti "06Cr11Ti") | ≤ 0.08 | | [06Cr13](/materials/gb/06cr13 "06Cr13") | ≤ 0.08 | | [06Cr13Al](/materials/gb/06cr13al "06Cr13Al") | ≤ 0.08 | | [06Cr15Ni25Ti2MoAlVB](/materials/gb/06cr15ni25ti2moalvb "06Cr15Ni25Ti2MoAlVB") Indicative | 0.03–0.08 | | [06Cr15Ni25Ti2MoAlVB](/materials/gb/06cr15ni25ti2moalvb "06Cr15Ni25Ti2MoAlVB") Indicative | ≤ 0.08 | | [06Cr16Ni18](/materials/gb/06cr16ni18 "06Cr16Ni18") | ≤ 0.08 | | [06Cr17Ni12Mo2](/materials/gb/06cr17ni12mo2 "06Cr17Ni12Mo2") | ≤ 0.08 | | [06Cr17Ni12Mo2N](/materials/gb/06cr17ni12mo2n "06Cr17Ni12Mo2N") | ≤ 0.08 | | [06Cr17Ni12Mo2Nb](/materials/gb/06cr17ni12mo2nb "06Cr17Ni12Mo2Nb") Indicative | ≤ 0.08 | | [06Cr17Ni12Mo2Nb](/materials/gb/06cr17ni12mo2nb "06Cr17Ni12Mo2Nb") Indicative | ≤ 0.08 | | [06Cr17Ni12Mo2Nb](/materials/gb/06cr17ni12mo2nb "06Cr17Ni12Mo2Nb") Indicative | ≤ 0.035 | | [06Cr17Ni12Mo2Ti](/materials/gb/06cr17ni12mo2ti "06Cr17Ni12Mo2Ti") | ≤ 0.08 | | [06Cr17Ni7AlTi](/materials/gb/06cr17ni7alti "06Cr17Ni7AlTi") | ≤ 0.08 | | [06Cr18Ni11Nb](/materials/gb/06cr18ni11nb "06Cr18Ni11Nb") | ≤ 0.08 | | [06Cr18Ni11Ti](/materials/gb/06cr18ni11ti "06Cr18Ni11Ti") | ≤ 0.08 | | [06Cr18Ni12](/materials/gb/06cr18ni12 "06Cr18Ni12") | ≤ 0.08 | | [06Cr18Ni12Mo2Cu2](/materials/gb/06cr18ni12mo2cu2 "06Cr18Ni12Mo2Cu2") | ≤ 0.08 | | [06Cr18Ni13Si4](/materials/gb/06cr18ni13si4 "06Cr18Ni13Si4") | ≤ 0.08 | | [06Cr18Ni9Cu2](/materials/gb/06cr18ni9cu2 "06Cr18Ni9Cu2") | ≤ 0.08 | | [06Cr19Ni10](/materials/gb/06cr19ni10 "06Cr19Ni10") | ≤ 0.08 | | [06Cr19Ni10N](/materials/gb/06cr19ni10n "06Cr19Ni10N") | ≤ 0.08 | | [06Cr19Ni13Mo3](/materials/gb/06cr19ni13mo3 "06Cr19Ni13Mo3") | ≤ 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.
